How To Get Rid Of Woolly Bear Caterpillar

Why Are Woolly Bear Caterpillars Pests?

Wooly bears are mostly harmless to humans as they don’t bite and are non-toxic. However, the bristles in their bodies can cause severe irritation to the human skin.

Adding to that, they actively eat the leaves of flowering plants, leaving big holes in them. This affects the aesthetic value of your flowering garden and can also be dangerous for the plants.

They also infest other useful leafy vegetables like spinach and cabbage.

Due to these reasons, wooly bears are considered as pests, no matter how cute they look from afar or how well they predict the weather!

How To Get Rid of Them Naturally?

As mentioned above, these fuzzy caterpillars can be a big problem for your garden. Therefore you need to take proper measures to eliminate them.

It is good to use natural ways to get rid of them, as chemicals and insecticides can affect the fertility of the soil and also kill other beneficial insects.

Here are a few tricks that you can use to get rid of caterpillar infestations naturally.

Woolly Bear

Use a mixture of pepper and garlic

A mixture of pepper and garlic can be used in a homemade spray to remove the woolly bears. Dissolve the pepper-garlic mixture in some water and put it in a sprayer.

Once that is done, sprinkle it directly into the worms, and as the liquid gets absorbed in their bodies, it will slowly kill them.

You can also spray it on plants and trees to keep these pests away.

Use Vinegar

Most caterpillars don’t like the smell of vinegar. Therefore you can sprinkle a few drops of it in areas where you notice regular caterpillar activity.

This will drive them away from those spots, and they might look for other nearby plants to infest. You can also keep some decoy plants that are non-flowering so that they can move to those instead.

Remove logs and debris

During the winter, these caterpillars come to your yard in search of a warm spot to hibernate.

Unattended logs and debris are the perfect spots for them to live. This is why you must keep your yard clean and don’t leave debris unattended.

Invite birds to your yard

Birds are one of the topmost predators of wooly bear caterpillars; therefore, having regular visits from them will be beneficial for you.

To attract these birds to your garden, you just need to find the right feeding seeds and sprinkle them in the yard, and they will finish the majority of caterpillars from the spot.

Use a worm barrier

Worm barriers are tough piece of cloth that is wrapped entirely around a plant to keep it safe from pests.

These are ideal for keeping flying insects like moths away from plants. Since wooly bears the larval form of tiger moths, the barrier will restrict the adult moths from laying eggs in the plant.

This will keep it safe.

Other Methods to Remove Them

Before using any insecticides to get rid of woolly bear caterpillars, make sure that they are not harmful to other beneficial insects.

Mentioned below are two safe chemical methods that you can use to get rid of wooly bear caterpillars from your garden:

Pheromone traps

As the name suggests, these traps use pheromones to lure insects. Here, once the insects fly to the trap, they get stuck on a sticky surface.

Put it in areas where tiger moths usually show up to lay eggs, and if you kill the tiger moths, they won’t be able to lay the eggs.

Bacillus Thuringiensis Berliner

The Bacillus Thuringiensis Berliner is a bacteria that is highly effective in killing wooly bears.

The good news is that this bacteria doesn’t cause any harm to plants and is environmentally safe to use.

It is also an active ingredient in many of the insecticides that help to control pests from damaging useful plants.

How To Prevent Them From Infesting Your Plants?

Here are a few useful ways to them these species of caterpillars away from plants:

  1. Make a homemade pepper spray using peppers, onion, garlic, and water. Dissolve it properly and spray it on the plants to keep these pests away.
  2. Catch the caterpillar crawling in your garden with a glove and put them in a bucket full of lukewarm soapy water; this will kill these pests instantly. Throw away the dead caterpillars from the solution and repeat the process.
  3. Have plants like cilantro, aster, basil, yarrow, and more in your garden. The aromatic smell of these plants will drive the pests away.

Frequently Asked Questions

Are woolly bear caterpillars destructive?

Wooly bear caterpillars do not destroy anything in your home, but they can destroy the precious plants in your gardens.
Being herbivorous in nature, they need a lot of food which they obtain from eating leaves of herbaceous plants, trees, and leafy vegetables.

How long do Wooly bears stay caterpillars?

It usually takes a few weeks for the wooly bears to start the pupating process, but there are some species of wooly bears that take much longer than this.
For example, the arctic moth can take up to 14 years to become a complete adult.

What does a lot of woolly bear caterpillars mean?

If you find a bunch of wooly bears in your yard, it is probably because there is a lot of food available for them in your yard.
Moreover, it might have nice warm spots where they can hibernate throughout the winter before emerging as big healthy tiger moths.

Will vinegar stop caterpillars?

Yes, vinegar is an effective substance to get rid of caterpillars. Usually, the caterpillars do not like the smell of vinegar.
Thus, spraying a few drops of it in worm-infested areas can really help to drive them away from the area.

Wrap Up

Wooly bears might be harmless to humans, but they are bad news for your garden. These insects will chow down on the leaves of your favorite plants, making them look hideous.

On top of that, once they grow up to become moths, it is gross to have them flying around your garden.

Therefore use the tips and tricks given in the article to get rid of them, and always remember that it is wise to use natural remedies instead of using chemicals that affect the plants and the soil.

Thank you for reading the article.

Reader Emails

Wooly bear caterpillars have many cultural connotations, but at the end of the day, a pest is a pest. Many of our readers have reported how these caterpillars have destroyed leaves on their ornamental plants. 

Moreover, their hair can also cause itching and allergies in humans, which is another problem when these bugs are present in large numbers in the garden.

Do read about the experiences of our readers with regard to them.

Hi Elaine,
This is actually a Tiger Moth in the family Arctiidae, most likely from the genus Grammia. There are many similar looking moths in this genus and we do not feel confident trying to identify your specimen to the species level, but a glance at the images on BugGuide will show you some possibilities.

Hi Emma,
Though this is a Tiger Moth, it is not a Mexican Tiger Moth which is only reported on BugGuide from the southwest.  BugGuide has a nice representation of Tiger Moths and there are several genera that look very similar, including
Apantesis, Grammia and Notarctia which is where the Mexican Tiger Moth is classified.  Exact species identification might not be possible without an examination of the specimen, but we would guess that this is most likely a Tiger Moth in the genus Grammia, If you are interested in learning more about your local moths, you should see if there is a National Moth Week event in your vicinity.

My kids and I love bugs. We found an egg sac in our yard that we have not seen before. We have been keeping an eye on it for a about a month (although I don’t know for sure how long it had been there before we found it). It hatched this morning and we found a beautiful moth (which we also have not seen before). I’m hoping you can give us some more info about what kind of moth it is exactly. Thanks so much.

Tiger Moth:  Grammia ornata

Hi Christie,
This is a beautiful moth.  It is a Tiger Moth in the subfamily Arctiinae, and it looks like a member of the genus
Grammia, however we are having difficulty finding a visual match on BugGuide because of the black base on the underwings and the intricate pattern on the forewings. We also find the cocoon to be unusual in that no caterpillar hairs have been incorporated in its construction.  We have decided to contact our friend and Arctiid expert Julian Donahue for his opinion.

Tiger Moth
Tiger Moth:  Grammia ornata

Hi again Christie,
We emailed Julian and then telephoned, but he is running errands.  We now believe this is
Grammia ornata, and you can see a selection of images on BugGuide including this image on BugGuide which shows the black base to the underwings.  The species is found in California.  We are awaiting confirmation from Julian.  We could not locate an online image of the cocoon of Grammia ornata for comparison. 

Unidentified “Cocoon”

Julian Donahue Confirms Identification:  Grammia ornata
You’re right on, Daniel. Grammia ornata is a western North America species, occuring from Ventura Co., California north through the Pacific Northwest to southern British Columbia, Canada, east to northern Utah, and western Wyoming and Montana. (South of Ventura Co., California, it is replaced by the similar G. hewletti, described from San Diego Co., California).
Attached is a copy of Chris Schmidt’s revision of Grammia, which has color plates illustrating all the species. Both species are illustrated on p. 578, figs. 36 & 37.  Schmidt_2009_Grammia

Thank you so much for your reply. I was wondering about the cocoon/egg sac as well. It looked like thousands of tiny oval eggs inside a silk web, but in the shape of a caterpillar. This one was on our deck under a planter, but we found two more on the underside of leaves  on a  nearby plant with the web curling the leaf around it. We have not seen any actual caterpillars in the garden, so now I’m wondering the sac and the moth were coincidental occurrences?? I would love to know more about the cocoon/sac if possible.
Thanks again!

Hi Christie,
In your original email, you implied that you were certain the moth emerged from the cocoon.  Now you don’t seem certain.  In our opinion, the moth and the cocoon are not related. 

Julian Donahue confirms our suspicions about the “Cocoon”
The “cocoon” doesn’t look like anything I’ve ever seen; almost 100% positive it’s not arctiid in origin (sorta looks like a sawfly larva to me, but that’s a wild guess and I have nothing to back it up).

This little bit of loveliness is a Tiger Moth commonly called the Virginian Tiger Moth
, Spilosoma virginica.  Though the yellow abdomen is quite distinctive on this dazzlingly white moth, very few of the images on BugGuide showcase that feature, except this image on BugGuide with the wing being held by fingers.  In that sense, your image displaying the abdomen is an internet rarity.  Despite the misleading name, the Virginian Tiger Moth is found across the country from the Atlantic Ocean to the Pacific Ocean.  I hope you are well Bettina.

We saw a rather striking moth (by its antennae) in Delta, Utah (around 19 August) during daylight on the stucco wall outside our motel room. The moth was then blown off the wall by wind and fluttered to a nearby shrub, where I captured it and took the attached photo. I released the moth in a sheltered place (inside the foliage of another shrub) out of the high wind and where birds would not see it. The moth had geometric black triangles on white wings… it almost looked like an African batik fabric pattern. I haven’t seen another moth like it during our travels since then. When I rediscovered a photo, I thought I’d ask if you have any idea what it is? Thanks! Buggy Best Wishes,

Hi Mitzi,
In order to streamline our posting, we will try to identify your creatures one at a time. BugGuide identifies this moth as one ot the Tiger Moths in the genus Apantesis and says: “Identification of species is difficult, and the taxonomy may still be rather confused. ” Our Insects of the Los Angeles Basin by Charles Hogue shows a nearly identical moth, Hewletts Tiger Moth, Notarctia hewletti, but we suspect the taxonomy is outdated.

Unknown Mexican Moth

Hi David,
Thanks for writing back and providing a location.  Though it resembles the Giant Leopard Moth of the U.S., this is a distinct species.  Its legs are quite distinctive.  Though we believe it is a Tiger Moth, we aren’t certain.  We will contact Arctiid expert Julian Donahue to see if he can identify your moth.

Update from Julian Donahue
Mistaking this moth for a tiger moth is a common one–it has even fooled professional collectors from whom I used to purchase Mexican tiger moths for the Museum (consequently, we have a lot of them in the collection!). (ed. Note:  Los Angeles County Museum of Natural History)
The moth is in the Noctuidae (to which the tiger moths have been recently relegated as a subfamily: Arctiinae), in the subfamily Pantheinae. It is in the genus Lichnoptera, and its crisp black markings on a white ground make it very similar to Lichnoptera decora, the only member of the genus that occurs in the United States. Poole’s catalog of the world Noctuidae has 15 species of Lichnoptera, all but decora described from Mexico and various countries in Central and South America–and most of these are not as boldly marked as decora (I’m fairly certain that decora also occurs in Mexico). The larvae of L. decora have been reported feeding on apricot.
Julian P. Donahue

Another Correction
I believe this is an Owlet Moth (Noctuidae); subfamily Pantheinae.  It looks very similar to Lichnoptera decora, a species that also occurs in the southwestern USA, but it is virtually identical to photos of L. cavillator in my copy of “Butterflies and Moths of Costa Rica” (Chacon and Montero). Anyway, I believe Lichnoptera is the genus. Regards.

Hi Rossana,
Common names can create some confusion as often the same name is given to more than one species, and sometimes one species can have more than one common name.  The scientific binomial system is much more accurate, and it eliminates confusion when one species has a range that extends across countries that speak different languages.  We suspect the Leopard Moth you mentioned is
Zeuzera pyrinaYour moth is a Tiger Moth in the subfamily Arctiinae, and we believe it might be Chelis maculosa which is pictured on Hants Moths.  Additional images can be found on Moths and Butterflies of Europe and North Africa.  Another possibility is Cymbalophora pudica which can also be viewed on the Moths and Butterflies of Europe and North Africa.

Tiger Moth: Haploa species

We cannot currently access BugGuide, our favorite site for identifications of North American species, but we did locate images of the Reversed Haploa on Cirrus Images which states:  “They are clumsy fliers, their principle tactic being flying a short distance and hiding in the grass or low foliage (there are perhaps thousands of species that employ this tactic). Their camouflage does not appear effective in a foliage-green environment. They are hyper-alert and difficult to approach, perhaps as a result of their high visibility.”  Your Tiger Moth might be the Reversed Haploa, or it may be a different species in the genus.

We are especially happy we wrote back to you to notify you there were no images.  Though we immediately recognized this as a Tiger Moth, we needed to identify the species and we found the Northern Giant Flag Moth,
Dysschema howardi, pictured on the Moth Photographers Group, and we verified its identity on BugGuide were we learned that only females have orange underwings, meaning your individual is a female.  We also learned on BugGuide that this is the only member of the genus found north of Mexico:  “1 sp. n. of Mex. (a second sp. may have strayed once from Mexico).   There are some 90(!) species of Dysschema, mostly in South America.”  The species is also pictured on the Butterflies and Moths of North America site.  Though we have a single posting of the caterpillar of the Northern Giant Flag Moth, your submission is the only image we have in our archives of an adult.

Ed. Note:  This is one of the most beautiful North American moths that has ever been submitted to our site.  It is so incredibly delicate in pattern that we could not resist making it the Bug of the Month for August 2017.  According to BugGuide:  “‘Flag Moth’ is a common name coined for the subfamily Pericopinae by Hogue (1993).”  So, in a feeble attempt on the part of our editorial staff to explain the common name, this would be the northernmost ranging species in a genus in the Flag Moth subfamily Pericopinae recognized by Charles L. Hogue.

OMG! How exciting!!! I felt like there was something special about this moth. It’s funny, I seem to have interesting bug experiences when I travel here.

I found a map of historical sitings, and the closest one was well over a 100 miles south. It seems they live mostly south of San Francisco, and in the southwest. (I live in Siskiyou County, about 40 miles from the Oregon border.) So can you help me know which moth it is? It was so striking. Maybe climate change is bringing them further north?

Arachnis picta, and it is a relatively common species in Southern California.  Each year in the late fall and early winter, numerous individuals are attracted to the porch light at our Mt Washington, Los Angeles offices.  We frequently see and photograph mating pairs and females laying eggs.  The eggs hatch in about 10 days and after a first meal of the egg shell, the minuscule caterpillars disperse, becoming general feeders of the Woolly Bear type.  We are happy to hear that you are enjoying and learning from both the website and Daniel’s book.

Thank you so much for replying me so soon.
All the best,

Letter 27 – Painted Tiger Moth

This moth got into my house a few nights ago(10/17/2011) in Ramona, CA. I came inside and found it on my lamp shade. Took a picture and let him go. Could you tell me what it is? I’ve been looking for something like it online and haven’t had any luck. It’s a very beautiful creature!

Just an update to the previous posting.  We believe the first Tiger Moth to arrive, the one on the lower left, is a female and we believe she released pheromones to attract a mate. Which will she choose??? In the past Painted Tiger Moths have laid eggs on the siding.  It seems we get several Painted Tiger Moths visiting each year, but we are still thrilled when we spot the first of the season.

Letter 30 – St. Lawrence Tiger Moth


what’s this moth?
Hi, I found your site useful, and already identified a Cerisy’s sphinx moth based on one of the photos someone else sent in. Can you tell me what this moth is? I photographed it in Chetwynd, British Columbia, in early Jun. It was just sitting on the sidewalk early in the morning.

Hi Melanie,
Based on an image we found on BugGuide, we are relatively certain this is a St. Lawrence Tiger Moth, Platarctia parthenos. It is a new species for our website.

Letter 31 – Ranchman's Tiger Moth


What kind of Moth is this?
I have looked through your archives and can’t find any pics of the moth my daughter hatched? Any ideas what it is? We have another due to hatch in a week or so. Thanks for your time,

Hi Lisa,
The reason you couldn’t locate this Ranchman’s Tiger Moth, Platyprepia virginalis, on our site is because your images are the first of this species we have received. The Ranchman’s Tiger Moths on BugGuide were found in Montana and Oregon.

Five Spotted Hawkmoth and Nevada Tiger Moth, we believe

Hi Mike,
This photo of a Sphinx Moth and a Tiger Moth getting along is priceless.  The Tiger Moth is probably the Nevada Tiger Moth, Grammia nevadensis, and you may read about it on BugGuide.  Because of the angle of the photograph, the Sphinx may be difficult to get an exact ID from us and will probably require an expert, but it appears to be in the genus Manduca, probably the Five Spotted Hawkmoth, Manduca quinquemaculatus.  That may be researched on Bill Oehlke’s awesome website.

Yes, I positively ID’d the hawk moth as a five spot.  We have lot’s of them around here.

Ranchman's Tiger Moth

Hi Dee,
We are so happy you have a lovely creature you would like identified as we have been fielding so many recent identification requests from folks who believe the Stink Bugs, Carpet Beetles and other creatures they have found in their homes might be Bed Bugs.  We identified your Ranchman’s Tiger Moth,
Platyprepia virginalis, by first going through the Arctiid Plates on the Moth PHotographers Group website.  Then we searched BugGuide where we found a nice posting that includes the eggs,  the caterpillars and the adults of this lovely allegedly diurnal Tiger Moth.  Your letter did not indicate the month of the year for the sighting.

I shot the photo in  mid-June of 2009, I was on Gold Cap Mountain, in Priest River, Idaho.

Letter 34 – Possibly Williams' Tiger Moth


Williams Tiger Moth?
Location: Roxborough, CO
July 16, 2011 8:02 pm
Hi WTB! You have many beautiful Tiger Moths on your website, but I didn’t see the Williams Tiger Moth – Grammia williamsii. My sister found this one on her porch today, in the prairie foothills southwest of Denver. At least I THINK it’s a Williams Tiger Moth… am I right? 🙂
Signature: Katie

Williams' Tiger Moth, we believe

Dear Katie,
The markings on your Tiger Moth look very similar to the markings on the photographs of the Williams’ Tiger Moth,
Grammia williamsii, that are posted on BugGuide, and BugGuide has data indicating that there have been sightings in Colorado, however, according to BugGuide, there are 38 species in the genus Grammia in North America as well as numerous subspecies.  Since many of the Tiger Moths in the genus Grammia look quite similar, this may be a near relative of the Williams’ Tiger Moth.

Hi mr bugman
I’ve been scouring your website and google looking for an identification of a moth i found on a wall of a house near Addo elephant park in south africa. It looks a lot like a salt marsh moth, yet is different. hasn’t managed to identify it, but its a exact match to my picture. hope you can help.

Tri-Colored Tiger Moth, we believe

Dear Frank,
Your unidentified moth does resemble a Tiger Moth and it is laying eggs that are consistent with the manner of laying eggs incorporated by many Tiger Moths, including a Southern California species called the Painted Tiger Moth.  We will contact our friend Julian Donahue who is an expert on the former family, which has been demoted to a subfamily, to see if he can provide an identification.

On Oct 18, 2013, at 3:58 PM, Julian Donahue wrote:
Nope. Don’t have any good African references here at home.
Appears to be a Creatonotus or Estigmene, sensu Hampson. But without seeing the complete wing pattern, abdomen, and venation, I can’t go any further.

At least you agree it is a Tiger Moth.  That means I got the subfamily correct.

Update:  December 29, 2013
Thanks to a comment, we are posting a link to a Tri-Colored Tiger Moth,
Rhodogastria amasis, from African Moths.

Possibly Diurnal Arctiid Moth

Dear Linda,
We believe this might be a Diurnal Moth in the subfamily Arctiinae.  Many members of this group, especially those in the subtribe Euchromiina (see BugGuide), are diurnal and they mimic wasps.  As you indicated, the quality, and more importantly the size of your image, is not ideal for identification purposes.  We will contact our friend Julian Donahue who is an expert on Arctiids and who has spent much time in nearby Costa Rica, because he may be able to help with a more definite identification.

Thank you for your help. After looking at images of Arctiids on the internet I do see that it is what I have. I’ll keep trying to get a better photo. Hopefully he doesn’t spend all of his time way up in trees.

Hi Daniel,
Yep, it’s an arctiid: Symphlebia hyalina (Rothschild), most likely subspecies amaculata (Rothschild), whose type locality is Colombia.

Letter 37 – Lesser Puss Moth from France


Subject: Moth ?
Location: Clisson, France
April 23, 2015 9:18 am
I spotted this beauty last summer, during Hellfest Open Air Festival (06 / 20-21-22 / 2014) in Clisson, France.
It landed on our tente on the first day, and almost not move for 3 days, despite the sun and the rain.
When we folded the tente, it flew away and landed on the top of a tree.
It was about 5-6 cm long, without antennae, it had hairy and soft paws.
I live in Nantes, near Clisson, and I’ve never seen that kind of bug before.
Does anyone ever seen the same beauty ? What is its species ?
Thank you so much for your help.

Tiger Moth we believe
Lesser Puss Moth

Dear Fleur,
WE believe that this is a Tiger Moth in the subfamily Arctiinae, but we cannot be certain.  We have attempted to search the UK Moths site because we don’t know of a French resource, and we have not had any luck with the identification.

Update:  April 25, 2015
Thanks to a comment from Cesar Crash of Insetologia, we now know that this is Cerura ermine, a Prominent Moth in the family Notodontidae, and that it is called a Lesser Puss Moth according to the Lepidoptera Breeders Association.

Letter 38 – Probably Tiger Moth Eggs, hatching in Germany


Subject: caterpillars
Location: Marburg, Germany
October 16, 2016 1:24 am
Hi! I am living in central Europe (Germany), at the edge of a mixed forest. I have built up a container garden last year which attracts many different insects. In September this year I found many eggs fixed to a leaf of gladiola Acidanthera bicolor. Some time later very small caterpillars hatched which started to rope down on very thin threads. I could not find out what that is and wanted to ask for your help. Thank you very much.

Probably Arctiid Eggs
Probably Tiger Moth Eggs

Dear Sabine,
We suspect that these are Tiger Moth Eggs from the subfamily Arctiinae.  We are reluctant to provide an actually species identification.  Many Tiger Moths are generalist feeders with caterpillars that eat plants often classified as weeds.  Tiger Moths also lay eggs on surfaces where there is no food, like the outdoor wall of a home near a light.  When the Caterpillars hatch, they begin feeding on the egg shell and then they disperse to hunt for edible plants.  Tiger Moth Caterpillars are often called Woolly Bears.

Sycamore Tussock Moth

Dear Ecuaprof,
This delicate beauty is a Sycamore Tussock Moth which we verified by comparing your image to this BugGuide image.  According to BugGuide:  “Overwinter as cocoons, adults emerge in May and June and lay eggs on the underside of leaves or bark of sycamore. Young larvae feed in groups, they scatter later.”

My son found a caterpillar in our back yard, we let him put it in a jar with lots of leaves and the next day it was in a I guess cocoon. I remember it had a few furry spots on the back, I think it was orange & black and it had two horns.
If you have any idea please let me know.
Thanks, Corissa

Tiger Moth Cocoon

Hi Corissa,
This is definitely a moth cocoon.  WE believe this is a Tiger Moth Cocoon.  The construction incorporating the hairs of the Wooley Bear Caterpillars is consistent with the cocoon of a Tiger Moth.

This is the cocoon of a Tiger Moth in the subfamily Arctiinae, but we cannot provide you with an actual species.  Caterpillars of Tiger Moths, commonly called Woolly Bears, incorporate shed hairs with silk when constructing cocoons.

Dear Aaron,
We are pretty certain this is not an egg case.  It looks to us like a moth cocoon, possibly the cocoon of a Tiger Moth from the subfamily Arctiinae.  See this Isabella Tiger Moth Cocoon from BugGuide for comparison.

  1. I’d be more inclined to ID this as Estigmene acrea, based on looks and collection data on for the time and location provided.

  2. Hello there David, and thank you for your prompt reply.
    Yet I see you’re making a mistake with your first option, which may be due to some flikr pictures portraying this same moth, while giving it the wrong name. When I found them, too, to test the name I run a cross-search using Zeuzera Pyrina , and I found a totally different moth from the one I photographed! I suppose the mistake may be due to the fact this is a European/Northafrican Moth, not so known by anglosaxons 🙂
    In any case, yesterday I found the answer via the site of the Italian Entomologists. The right name is the one you mention, too,
    Cymbalophora pudica (Esper [1785]) – used to be classified as Arctiidae, now Aerebidae.
    I am glad we’ve found her name!
    Here’s the Italian site I’ve mentioned

  4. i wish that cocoon egg sac thingy was identified as I have just found that exact thing on a geranium leaf in my “Happy Hut” (my greenhouse -the infamous & no longer made “Thinking Outdoors” greenhouse which looks like a large shed made by Rubbermaid-, which is more of a grow room due to our using various lighting sources for both light & heat as we live in New Jersey, but I totally digress….) & came upon this site doing a Google image search. Another site had found something similar & let the eggs hatch & they turned out to be tiny wasps! YIKES!!! Kill it w/ fire; NOW! Soooo not a fan of wasps as I was once stung over 75x & spent a week in the hospital. I don’t know what a sawfly looks like so I’ll have to do some searching to see what they are. I do have an adult female & a young male Praying Mantis in my Happy Hut. The male was living on the plants I have in a large urn from my garden that I keep thriving until next Spring & I caught the female hanging out on the vinyl siding of our house on Halloween evening & brought her in to keep warm. She rewarded my kindness by laying an egg sac last Tuesday , 3 November, 2015. Besides them I know there are the menagerie of usual suspects from pill bugs & aphids, house & blue bottle flies, little golden moths & ants, the occasional carpenter bee & yellow jacket wasps find their way in too so the mantises can feed on them instead of each other but I don’t know where this wormy looking cocoon thingy chock full o’ teeny tiny eggs came from! I now see that someone else commented before me about the possibility of wasps & I’m not going to douse the thing with alcohol & set it on fire to ensure death!!! I’m sure wasps (& spiders too) serve some sort of good purpose but having dealt w/ those horrid things & enduring hellacious agony from their stings & venom; I’ll not risk it. Maybe I’ll first offer it to the mantises (if I can find either of them) to see if they’ll eat it but no matter what; I’m not going to allow the eggs to hatch. Yeccccccch!

  5. By the way you described it I’m not so sure it was a wooly bear.they normally have one orange stripe across their back and the rest of them are black, they don’t have spots or horns. Not sure what it could be.
