snow insect
Location: mt rainier national park, washington state

we saw this 6 legged, spiny insect on a snowshoe in mt. rainier national park (washington) late feb 2012. from limited, ignorant research– it looks similar to firefly and lacewing larvae but not exact. wished we would have put something down there to show size-but didn’t- was at least 2 inches long. thanks

Hellgrammite in the Snow

Dear Jen,
This sure looks to us like a Hellgrammite, the larva of the Dobsonfly.  Interestingly, BugGuide has a photo, also from Washington, that was posted two years ago in February.  That individual is also in the snow and there was speculation about why it was in the snow.

Thank you so much-  very nice to get an answer so quickly.  we were right next to a spring fed beaver pond with numerous geothermal springs/vents.  if that makes any difference with the strange location (snow) of a typical aquatic  bug.
Again- thanks again-
Jen

Hi Jen,
Those details might be significant, but it is still interesting that there was another Hellgrammite sighting in Washington in the snow.

We were at the Mojave River and saw this bug in the water. It kinda looks like a larva of some sort, but in all honesty i have no idea what it is and was hoping you would be able to identify it for us.
Thanks for your time

Hellgrammite

Dear Green Family,
This is the larva of a Dobsonfly, commonly called a Hellgrammite.  Most of our specimens are of the Eastern Dobsonfly, though several species are known to range in California, however they are not well documented.  This is one of the Western Dobsonflies.  See BugGuide for additional information.

Tattooed Bug?
Location: South Texas Hill country

My husband found this creature on the underside of a rock in the Guadalupe River this summer. We had never seen anything quite like it and our kids think it looks like it has been tattooed. It is about 3 inches long.

Unfortunate circumstances in need of creature identification
June 5, 2011 8:49 pm
Dear Bugman,
I found this creature alongside the winooski river in winooski, Vermont a few days ago. I found him out of water but moving very little. I attempted to instigate a fight between this behemoth we dearly call “Petunia” and a wolf spider. To my dismay there was no battle. Petunia retreated to a small pool of water and became more active.
Perplexed by this creature I have adopted Petunia and am attempting to find out what to feed her. It may appear that she eats ants as she destroyed one when introduced to her pool.
However due to her gills, which are on both sides of her below her legs, I am unsure if she is even an insect.  Bugman I hope you can solve this mystery as Petunia must be getting hungry by now.
After writing you this letter I have realized I cannot attach images to your website from my iPhone and unfortunately it as all the internet access we have at my residence. If you respond I will send you the picture as an attachment with due haste.

found this while camping
Location: North eastern PA in woods

Hi, we found this bug at Promised Land State Park in PA. It was a moist morning and our neighbor found it on the cabin porch. He took a stick and was going to move it when it crawled on the stick but the darn thing started to fight with the stick!!
It was about 3-4” long and later when I tried to move it, it backed straight back like an inch worm goes forward.
Can you identify this critter?? thank you very much

puzzled in Pa?
Location: western Pa
May 22, 2011 10:00 pm
My boyfriend and I were out walking along the shore of the Ligonier Creek in western Pa, we spotted a nice location to sit and talk on a couple of larger rocks. My boyfriend picked up a smaller rock to skip across the creek when we came accross this insect. We both love being outdoors but we never saw a bug like this before. So we picked it up put it in a container and brought it home with us for further analysis. WE ARE STUMPED!! Can you help? We would like to release it back into the wild tomorrow. Thanks alot!
