Earwig sighting accompanied by maternal hysteria and book bashing!!!

A long bug called a Pricker bug, by the locals, has invaded my propert and even entered my home. I worry for my child’s safety.
August 22, 2009
The bug is long, about 2 inches in length, and very narrow body. It has a curved tail like a scorpion, but no pincher claws in the front like the scorpion. The pincher is on the end of the tail. Looked more like a stinger to me at first. It moves quickly, and when squished with a book, I had to push down HARD to kill it. It freaked me out because I thought it might be a scorpion of some sort, or at least a relative to the scorpion. My neighbor looked at the one I killed (I saved it in a baggy), and he called it a “Pincher” bug. But, I KNOW that’s not the correct name for this bug. He also told me they sting or pinch and it’s VERY painful. I have a child (who is allergic to almost all bugs, and has a severe reaction to even a tick or mosquito bite. A tick bi te swelled her entire face in the eye area and it looked red and puffy for days. People thought I beat my child because her eye was so swelled too.) in my home, and I am afraid she will unknowingly come across one and step on it or something, getting hurt. Are they poisonous? Are they dangerous? What are they?? I live in central Florida. I tend to seem them in the rainy times. They are dark colored, maybe black or dark brown. long and thin, tail curved up on end. Their shells are very strong, it was difficult to break it when I squished it with the book, took a couple times and alot of pressure before I heard the crunch. I hate bugs, and don’t usually go out of my way to kill them, just stay away from them. If I knew what this was, I could figure out how to get them gone from my yard, and when they come in the house. Please help me???? My main concern to find out about these bugs is to protect my daughter. Please help me to figure this out?? I will search for pics, and hopef ully I find one to send with this. If I don’t, I hope you have an image in mind already.

10038 euro earwigs 300x203 Earwig sighting accompanied by maternal hysteria and book bashing!!!

Dear Alexis,
Your inquiry has us totally baffled because you attached a photo lifted from the University of Nebraska Department of Entomology that clearly identifies your Pricker Bug as an European Earwig.  Armed with that information, the first website that pops up in an internet search is the Featured Creatures website that had quite detailed information on the European Earwig.  Earwigs are not poisonous, and though the forceps at the tip of the male’s abdomen can cause a slight pinch, your neighbor was exaggerating when he said it is “VERY painful.”  Comparing the pinch of an Earwig to the bite of a Tick or Mosquito, both of which can spread diseases, is irrational.  According to the CDC, a partial list of Tickborne Diseases includes Babesiosis (Babesia Infection), Crimean-Congo Hemorrhagic Fever, Lyme Disease, Southern Tick-Associated Rash Illness, and Tick Born Relapsing Fever.  Mosquitoes are an even more serious concern.  According to the AMCA website:  “Mosquitoes cause more human suffering than any other organism — over one million people die from mosquito-borne diseases every year. Not only can mosquitoes carry diseases that afflict humans, they also transmit several diseases and parasites that dogs and horses are very susceptible to.”  The National Center for Infectious Diseases website has the following partial list of Mosquito Borne Diseases:  Eastern Equine Encephalitis, Japanese Encephalitis, La Crosse Encephalitis, St. Louis Encephalitis, West Nile Virus, Western Equine Encephalitis, Dengue Fever and Dengue Hemorrhagic Fever, Malaria, Rift Valley Fever, and Yellow Fever.  Climate Change, Global Warming, and traveling around the world could cause some of these typically tropical diseases to surface in the U.S.  In our opinion, your squishing of an Earwig with a book constitutes Unnecessary Carnage.  You do not need to concern yourself with your daughter’s safety when it comes to Earwigs.

Butternut WoollyWorm

White cottony caterpillar
August 22, 2009
What is this?? My husband and I found several in our garden. We believe they are feeding on young sumac or lilac trees. We have studied caterpillars and moths/butterflies for some time and have never seen this before. Thank you for any assistance.

Butternut WoollyWorm

Hi Donna,
Though the Butternut WoollyWorm, Eriocampa juglandis, resembles a caterpillar and is often mistaken for a caterpillar, it is really the larva of a Sawfly.  Sawflies are classified with Ants, Bees and Wasps.  According to BugGuide:  “Larvae feed on leaves of Black Walnut (Juglans nigra) and Butternut (Juglans cinerea). Also reported on Carya spp. (Hickory).
“  The potential host trees you mention are not listed in any sources we used.  According to the Auburn University website:  “Fully grown larva are densely covered with white, cottony or woolly filamentous flocculence.

Oleander Hawkmoth Hornworm from India

Dear Roy,
This is a Sphinx Moth Caterpillar or Hawkmoth Caterpillar in the family Sphingidae.  These caterpillars are often called Hornworms for obvious reasons, and they are harmless.  The coloration of your specimen indicates that it was probably getting ready to pupate, which they do underground.  We will put in a quick inquiry with Bill Oehlke to see if he recognizes the species, and perhaps one of our readers will write in with a species identification.

Hi Daniel and Roy:
This looks like the caterpillar of the Oleander Hawkmoth (Daphnis nerii). It is native to southern Europe, Africa and Asia but is popping up worldwide as its host plant (Oleander) is spread as a popular ornamental. They are apparently well established in Hawaii for instance. The mature larvae are usually green but it does come in a variety of color variations; this is a brown form. The adults are very well represented on WTB and there has been at least one posting of a brown form caterpillar.  Regards.

Black Swallowtail

More Black Swallowtail on Long Island, NY
August 22, 2009
Your site was very helpful in identifying a butterfly that has been flying around Bayville NY this summer. I took two more pictures which feel free to add to that section of the site.
This is a female Black Swallowtail flying near a tomato plant, southern exposure. The pictures may not show the yellow spots at the bottom of the tail.

Thanks Barry,
The feeling of movement in your photo is a nice departure from the static images we generally post.

Hi Sirs
Just happened to be on here when your reply came in.
You are very polite about the “feeling of movement”- sorry if it’s a little blurred, but if you are able to use it, feel free. In the past, I have seen Monarch butterflies and sometimes Tiger Swallowtails, but I can’t remember seeing these Black Swallowtails in previous summers. Usually I see them at the dunes on the beach. Our house is about 100 feet from the beach, so some similarities. I can add that we had torrential rain last night so the plants are very moist. This particular butterfly was exploring (sniffing?) a tomato plant, getting very fragrant about now.
I took the picture to send to my daughter, who is in Southern Florida visiting relatives, possibly going to “Butterfly World” near Fort Lauderdale, hence I came on your site (via Google image search for “butterfly” and “Long Island”) to identify the pix before sending to her. She is a teenager now, but used to go there when she was much younger, did a project in school re rain forest in first grade, etc so maybe all this will rekindle her interest in butterflies.

House Centipede Comment

Thank You
August 22, 2009
Your website is the greatest! I am pretty phobic about bugs, but am trying to overcome it (and avoid Needless Carnage). I awoke earlier tonight to the sight of a extremely large specimen of house centipede on the ceiling directly over my bed. I had seen this guy once before in my bedroom, and really didn’t want to have to deal with disposing of him–yuck. Thanks to your website, I’ve learned that he is actually beneficial, so I’m going to stop freaking out and just leave him be for the time being (unless he ends up in bed with me!). I also wanted to share this entomology link on house centipedes with you: http://ento.psu.edu/extension/factsheets/house-centipedes. I particularly enjoyed the quote from a 1902 source, which is both amusing and still accurate today!

Luna Moth: Dead of Old Age

Beautiful green moth
August 21, 2009
I found this unusually large moth in July. It was 4 inches from tip to tip with green wings and gold antenna. Unfortunately, it was barely alive and died shortly after.

Luna Moth: Dead of Natural Causes

Hi Peter,
This is a Luna Moth, what most people consider to be the most beautiful North American moth.  At any rate, it is the most distinctive North American moth, and is not likely to be confused with any other native species by even the least observant individual.  Luna Moths do not feed as adults and only live a few days, long enough to mate and lay eggs.  Thanks for providing us with a view of the underside of the moth, a vantage we rarely receive.

Ailanthus Webworm Moth

I found this beauty on a table on my side porch. I live in the woods next to a reservoir in northern NJ. Any idea what this is?

Ailanthis Webworm Moth

Hi Kerri,
The caterpillar of the Ailanthus Webworm Moth, Atteva punctella
eats the leaves of the dreaded Tree of Heaven, Ailanthus altissima.  This noxious weed tree, a native of China, is invading native forest land from coast to coast.  It has long been a fixture in cities especially in areas of urban blight where it thrives.  It is the tree from  A Tree Grows in Brooklyn, the novel by Betty Smith.  Sadly the Ailanthus Webworm only eats the leaves of the tree and this does no lasting damage.  We would live to find an insect that bores into the trunks or roots and destroys the plant.  We believe the Ailanthus Tree might be the most dangerous invasive exotic plant to the native North American ecosystem.  Once it becomes established, it takes over, crowding out all other species.  You photo is quite beautiful.

Argid Sawfly, but what species???

Hi WTB, I found these creepy caterpillars chomping on my contorted hazelnut. Finally determined that they are sawfly larvae but can’t find an exact match on your site. They look like they are made of green jello – yuk! Any idea what species they might be? Thanks for all your help and for maintaining such a great site!!!

Sawfly Larvae on Hazelnut

Hi Laura,
We agree that this is an Argid Sawfly in the family Argidae.  According to BugGuide, the Birch Sawfly, Arge pectoralis, feeds on Hazelnut as well as birch and other trees, but the larvae have orange heads and the heads on your individuals are black.  We are pretty confident the genus is Arge, but we will have to postpone exact species identification.
