hi bugman!
This colourful flying insect had a collision with my brother’s mower. I think it’s a Stonefly. The closest match I’ve been able to find is Utaperla gaspesiana.
The eggbundle was attached to the insects abdomen.

Giant Stonefly with Eggs

Dear Storm,
While we agree that this is a Stonefly, we disagree with your species identification.  While the markings on
Utaperla gaspesiana as pictured on BugGuide look similar to the markings on your individual, we believe you have a Giant Stonefly in the genus Pteronarcys.  We were most curious about the egg bundle, so we did some research.  We located a similar photo on FlickR with the comment:  “Found this on a screen door, perhaps 100 yards from a brook. Large (2″?) egg-laden female. I think it may be Pteronarcys dorsata. May 28, 2011.”  The photographers, Jerry Schoen took the image in White Oaks, Williamstown, Massachusetts.  That same photo can be found duplicated on numerous other websites including The River’s Calendar.  The Elk River Guiding Company website also has a photo of a Stonefly with Eggs.  You can read more about Giant Stoneflies on BugGuide.

Hello!
My dad found this fellow in Virginia. He was unable to identify it and I’m stumped as well. We thought you all might have better luck.

Several of these were walking on top of a snowdrift in central-western Massachusetts after the blizzard 02/10/2013. They were about an eighth of an inch long at most. I didn’t realize that bugs could live outside in the winter. Maybe their nest was disturbed by the snow breaking off dead tree limbs or something like that.
Thank you!
PS: They look a lot like the bug drawing on your website here!

Small Winter Stoneflies

Hi Kandy,
Not many insects are found in the snow, but these Small Winter Stoneflies which are also known as Snowflies are frequently found on the surface of the snow.  The drawing you refer to is actually an Earwig.

Hey bugman :) today my husband nd i decided to take our four year old or a walk around the reservoir. Its early February in were in central Pennsylvania. We came across this bug just walking around in the snow. We would love to know what it is! Can you help?

Small Winter Stonefly

Dear S*C*A*M*,
There are a few insects found in the winter on the snow that are commonly called Snowflies, and this is one of them.  This is a Small Winter Stonefly in the family Capniidae.  Their presence near your reservoir is an indication that the water quality is quite pure as they cannot survive in polluted waters.

Thank you so much! We’re happy to have these little guys around if it means we have clean water! Its interesting how they survive in such cold conditions!

I took photos of several of these exoskeletons (at least I am assuming that is what they are) on rocks by the Clearwater River near Kamiah Idaho last week (mid-Oct.). When I opened up your website I was so excited, because there was a drawing of this creature. But it doesn’t tell me what it is. I’ve searched your lists (not all, but many) and can’t find it either. Can you help me scratch the buggy itch in my brain? Thanks!

Stonefly Exuvia

Hi Salli,
The bug in the drawing is an Earwig, but this is the exuvia of a Stonefly naiad.

Good day Bugman.
I found this little guy in the bottom of a bucket at our camp on the weekend. Could you tell me what he is? It looks alien :)
Thanks

Stonefly Naiad

Dear C.A. Brown,
This is the Naiad of a Stonefly.  A Naiad is an aquatic larva that eventually becomes a winged adult.  We cannot tell you the exact family, but this Naiad somewhat resembles this Common Stonefly Naiad from BugGuide.

hi there. I live in Labrador Canada and every summer we get this bug and no one knows what they are. I was hoping you could help identify it.
Thanks

Giant Stonefly

Dear n/a,
This is a Giant Stonefly in the genus Pteronarcys and you can compare your individual to this photo from BugGuide.  Stoneflies have aquatic nymphs or naiads, so they are generally found near a source of water.  Having a healthy Stonefly population is an indication that the nearby water is relative pure and pollution free as they cannot tolerate contaminated water.

This crawled/flew in my daughter’s drink cup in our kitchen. We’ve not seen anything like it before. It doesn’t look like any termite photos we’ve found, but we’d like to be sure and know what it really is. It’s dying in these photos so the legs are bending. It was about 5/8” long.

Common Stonefly

Hi Rik,
While we are not certain of the species, this Common Stonefly looks very much like the photo of
Perlesta nelsoni that is posted on BugGuide.  According to BugGuide, they are also called Golden Stoneflies.  Stoneflies are benign creatures and you have nothing to fear from them.
