CORRECTION: NOT Imperial Moth Lays Eggs

Imperial moths
HI
I love your site and have used it often finding out the names of insects for my small Daycare. I found an Imperial moth this morning and put her into a butterfly cage we have and after some hours let her go so she wouldnt die. On a leaf in the cage are tiny yellow eggs so I guess she was doing more then we thought in there. I kept the eggs and would like to know some information on them. How long does it take for them to hatch? After hatching what do the little ones eat? How long before they will start to make cacoons? Thanks so much,
Karen Maier

NOT Imperial Moth Eggs with Caterpillars showing
(08/12/2007) Imperial moth eggs, me again w. photo
Hello,
Have a great photo of the eggs I wrote you about acouple days ago. I couldnt believe I could actually see the little guys in there. Isnt it great. LOL I will take other pics as they grow but at this rate it probably wont be long before we have little ones running around.
Karen Maier

Hi Karen,
Feed them leaves from a wide variety of trees including Bald Cypress, basswood, birch, cedar, elm, hickory, Honeylocust, maple, oak, pine, Sassafras (Sassafras albidum), Sweetgum (Liquidambar styraciflua), sycamore, walnut. Visit BugGuide links for more info.

Hi Karen,
Thanks for sending in your photos of developing Imperial Moth Eggs. We eagerly await updates on the caterpillars progress.

NOT Imperial Moth Eggs Hatch
(08/14/2007)
Well its only been about 4 hours since I took a photo of them and sent it. But checking on them at lunch time gave us a surprise, they were hatching. So I grabbed 4 or 5 different types of tree leaves to put in the cage. Do they need water?? or is the leaves enough. I really want the little guys to have a chance or turning into those beautiful Imperial moths.
Karen Maier
PS let me know if u want any more photos as they grow or if you have enough of that type. dont want to send any you cant use.

Hi Karen,
These are not Imperial Moth caterpillars. We fear you misidentified your original moth. BugGuide has an image of a newly hatched Imperial Moth, and it does not look at all like your caterpillars. We cannot identify your specimen from this hatchling image. We suspect this is still one of the Giant Silk Moths. If you describe the moth, we may be able to identify it. It would be great if you could take a photo at each stage of development, known as instars. Each time a caterpillar molts, there is a new instar. There are five instars before pupation. You caterpillars will fulfull their water needs through the leaves they eat. Thank you for noting in your photo title that the eggs hatched after four days.

Callosamia species laying eggs: Promethia Moth or Tulip Tree Silkmoth????

tulip tree silk moth?
Hello! I thought this picture was unique and wasn’t sure if it was a tulip tree silk moth- thanks for your help!

Hi Catherine,
This is definitely a moth in the genus Callosamia, but we are unsure if it is a female Promethia Moth, Callosamia promethea, or a female Tulip Tree Silkmoth, Callosamia angulifera. Our inclination is that it is a Promethia Moth, but we want to try to contact a true expert, Bill Oehlke.

Female Dobsonfly eats Blueberries and lays Eggs

Blueberries for Bailey
Hi, and thanks for such a wonderful website! Thanks to your site we were able to identify our dobsonfly. My boys named her Bailey. We’d also like to confirm that adult females do eat. I read they liked blackberries but having none I substitued blueberries and she does indeed like them. I have video of her mouthparts working the blueberry. She lives in this cage but freely comes and goes at will as the top of the cage is open. Our question is has she laid eggs? There is a frothy looking white patch in the third picture. Thanks a billion bugs!
Mary, Cal, and Cade
P.S. If these pics are too big I can resize them. I wasn’t sure what works best for you.

Hi Mary, Cal and Cade,
This is an exciting submission for us. We have always believed that adult Dobsonflies do not eat. We will see what Eric Eaton has to say about the blueberry diet. Additionally, we do believe Bailey has laid eggs. The Featured Creatures website states: “Eggs : Dobsonfly eggs are gray, cylindrical and a little less than 1.5 mm in length and 0.5 mm in width. They are laid in clusters (about 2 cm in diameter) with an average of approximately 1,000 eggs/cluster (Baker and Neunzig 1968, Mangan 1992.). The eggs are arranged in three layers, and the egg mass is covered with a clear fluid by a brushing motion of the tip of the female’s abdomen. The clear fluid dries to a white color. Superficially, the egg masses resemble large bird droppings. ” That seems like an accurate description of what your photo depicts.

Wingless Female Tussock Moth Laying Eggs

Egg Laying??
Hi Bugman…this one really has me stumped. Found it in my backyard this morning. Hopefully you can help me out on this one. Thanks

Hi Tom,
This is an exciting photo for us since we get so many requests to identify White Marked Tussock Moth Caterpillars, Orgyia leucostigma. The female Tussock Moth is flightless and lays a foamy mass of eggs. This image agrees with one posted on BugGuide.

Cecropia Moth and resulting Caterpillar Hatchlings

Cecropia Moth Hatchlings
Hi Bugman…I photographed this cecropia moth on June 8/07 after it laid eggs and the eggs hatched on June 19/07. I really enjoy your site and appreciate how much work goes into keeping it going. I noticed you don’t have these eggs on your site so thought they might be a good addition.

Hi Tom,
Thanks for sending us your Cecropia Hatchling image. We linked back to your excellent stock photography site and we hope that doesn’t crash your server.

Heteropteran Eggs and Hatchlings: Probably Coreid Bugs

Some sort of treehopper?
… noticed the eggs on Tuesday, found the hatchlings on Wednesday … cheers,
Rich Parker (Alexandria, VA)

Hi Rich,
In a very general identification, these are Hemipterans. The Hoppers used to be considered a separate Order, Homoptera, but now Hemiptera and Homoptera are viewed as the same order, Hemiptera, and Heteroptera comprises the old classification and is termed the True Bugs. These are probably in the Family Coreidae, the Big Legged Bugs or Leaf Footed Bugs but newly hatched specimens are often very difficult to properly identify and we do not recognize the eggs. Perhaps you will be able to provide us with photos of adult specimens in the future which will assist in correct identification. BugGuide has a photo of your eggs, but with the same general identification we have provided.

Chalcid Wasp emerges from Parasitized Eggs

Hey bug guru
I cant tell you how much I appreciate your dedication to one of my geeky passions. Your time and work does not go unappreciated. Please evaluate the attached photos. I hope they meet your guidelines for size. I found a few small eggs on a leaf in a ficus tree in the front yard. Lucky me, I just purchased a new microscope.

The egg pictures were taken at 100x and the hatch was taken at 50x. I live in Mesa AZ. I found the eggs on 4-21-07 and they started hatching on 4-27-07. The little bugger started to warm up and moving subjects at 50x are hard to capture. When he, sorry, or she was fully stretched out it looked like a miniature wasp. Im thinking some kind of boring wood wasp, but Im sure you will set me straight. The attached photos are composite images of over 60 taken on each final photo. The 5mp camera and the Image-Pro Express software are impressing the you know what out of me. The eggs are about half the size of a pin head. In some of the photos you can see small particles of dirt on the side of the eggs. Thanks to you and yours for all your work Thanks
Danny
Empire Fluids Lab

Hi Danny,
These are pretty awesome images, though hearing that they are composite has us a bit troubled. We hope the integrity of the actual even is faithful. We suspect that this is some species of Chalcid Wasp. Chalcid Wasps parasitize other insects, and according to the USDA: “All chalcidids are parasitic. Most attack pupae of Lepidoptera and Diptera, but some parasitize other Hymenoptera or beetles. Parasites of Lepidoptera usually attack young pupae, while those of Diptera attack mature larvae (Clausen 1940).” often Bugguide doesn’t have any documentation quite like this, and as the wasp and host are quite specific, we will see if Eric Eaton can assist us in identifying the eggs and wasps. We will also try to contact Bill Oehlke who operates an awesome Sphingidae page since these eggs look like they might be Lepidoptera eggs, and the Ficus Sphinx is a moth that feeds on Ficus. Thankfully, you not only provided us with awesome images, but with enough background information to continue sleuthing until we exhaust our means in the identification.

Daniel,
Thank you so much for you work on this. I want assure you that my integrity is of the highest. I have sent you picture’s in the past. This Leica will not let me take a clear single image and to appreciate the details of the egg I spent a bit of time stacking multiple images. Im dedicated to the appreciation of mother natures gifts. … Thanks again for all your time dedicated to informing the world on BUGS. It is nice seeing others around the world send pictures and how the site is growing. Thanks
Danny

Hi Danny,
Consider us chastised. There has been much publicity in the world of photo journalism due to photographers combining images digitally that, while they convey the truth of the experience, are still considered tampering. Your photos are quite gorgeous and the effort you have expended to assure detail in every portion of the image is obvious. We hope that both Bill Oehlke and Eric Eaton respond to our queries. Though we do not know the exact species here, we are still confident that your images are of a Chalcid Wasp. Thanks again for writing.

Update: (05/09/2007)
Daniel:
Chalcids are out of my league, sorry! There are a few critters that just aren’t easily grasped in terms of ID, and those are among them.
Eric

Update: (05/10/2007)
Daniel,
I have never seen Pachylia ficus eggs so have nothing to compare these with. All of the Sphingid eggs that I have seen have been green, very smooth and without the upper ring, but I have not seen any under such high magnification. I am not an expert on wasps but I do know that some wasps parasitize eggs. Sorry I cannot be of more help. I suspect caterpillars of many species from many different families feed on Ficus.

Possibly Bryozoans

eggs in a lake?
Fantastic site guys…Thanks for the hard work. OK Here’s the scene: We live in Nothern NJ on a freshwater lake. In late September, I pulled this mystery cluster out of the water. It was attached to a rope that had been hanging off our dock, about 18" deep. I was with a friend who is an avid outdoorsman, and he’d never seen anything like it. .It was gelatinous and semi translucent inside with a coarser exterior. I’ve seen these clusters before on drfitwood, but remain baffled. Any ideas?
Jim

Hi Jim,
Both Amphibians and Snails lay eggs in a gelatinous mass, but we dont believe this to be either. We think it is a Bryozoan Colony of the animal phylum Ectoprocta. This marks a brand new page for our site.

Unknown Eggs

Unknown
Hi,
These are apparently very ornate eggs of an insect. I’m told they’re not from butterfly or moth.They are magnified in the image (probably 15x). They were attached to a sedge, Carex hormathodes, high among rocks along the coast of Narragansett Bay in RI. I have never been able to figure out what they might be from.
Thanks
Francis Underwood

Hi Frances,
We don’t recognize your eggs, but suspect they might be from some Hemipteran or True Bug. We are posting in the hopes that one of our readers might be able to assist you. We are also posting the date you printed on the photo, August 12, 2004, as that might be significant.

Newly Hatched Imperial Moth Caterpillars

Really cute caterpillars
Hello Bugman!
Last Summer, in my yard, I found a large yellow and brown moth. It was being bullied (stung) over and over by a yellowjacket. I killed the bee and scooped up the moth and brought it onto my back porch. I put “her” into my butterfly keeper from pre-school and left her on my back porch with a mixture of sugarwater for butterflies, lots of leaves, some dirt and a shallow bit of water. Much to my surprise she began to lay tiny little yellow eggs. She died soon after. I felt so sad for her. Not knowing any better, I thought the little eggs would stay eggs till the next season. Boy was I excited and covered up in tiny little caterpillars one day! I put them outside in hopes they would find whatever they needed. These are the pictures I took of them. I could see each tiny life inside each tiny egg! It was so beautiful! Thank you for such a wonderful web site!

Hi Rene,
BugGuide has an excellent example of the life cycle of the Imperial Moth. We are happy to get your images of newly hatched Imperial Moth Caterpillars. .

Katydid Eggs

Another Katydid egg photo
You’re site is fantastic! I was able to identify these eggs that I found on a hanger in my basement. We live on a farm in an old farmhouse (in Iowa). Our basement plays host to numeours treefrogs, toads, & salamanders so there was no telling what these things were. Any additional information you have on hatching them would be appreciated. There is no better learning tool than to experience real life science. I’m very fortunate in that my daughter (7 years) loves bugs, snakes and nature as much as I do! We’ve used your site to identify several caterpillars and moths that share our corner of the world. Thanks so much for all your efforts!
Sandy & Miya McAntire

Hi Sandy and Miya,
Keep the eggs cool or they will hatch too early. They will hatch on their own. The young Katydids will eat most green leaves, but tender spring foilage will be best.
