Hi. When I was walking i found this what i believe to be a type of stonefly but couldn’t identify it. Could you please tell me what it is? The insect was with what i guess was it’s mate foraging for food. They were beside an estuary where they occasionally were flying off then returning. The insects averagely were about 7 cm within length. The Picture Should have sent with this e-mail, The Geographical location is estimated but i hope the location should help Thanks.

Stonefly

Stonefly

We agree that this is a Stonefly in the order Plecoptera.  We have determined that your global coordinates are in the UK.  This appears to be a flightless species as the wings do not look long enough to allow flying.  Alas, we have been unable to locate any matching Stoneflies online.

My friend took pictures of these bugs and we cannot figure out what they are.

Stonefly Exuvia

Stonefly Exuvia

Dear Emil,
These are the Exuviae or cast off exoskeletons of aquatic nymphs of Stoneflies, known as a naiads, so we are guessing these images were taken close to a stream or river.  Of the Stonefly family, BugGuide notes:  ”
nymphs occur primarily under stones in cool unpolluted streams; some species occur along rocky shores of cold lakes, in cracks of submerged logs, and debris that accumulates around stones, branches, and water diversion grills.  spring and summer adults may be found resting on stones and logs in the water, or on leaves and trunks of trees and shrubs near water; winter stoneflies are often attracted to concrete bridges over streams, and some species are commonly found on snow or resting on fence posts during the warmer days of late winter.”  Though we cannot be certain of the species, your images resemble the Exuviae of the Beautiful Stone, 
Paragnetina immarginata, which is pictured on BugGuide.  Since one of your images appears to be up-side-down, we are guessing they may have been taken on a bridge overhang.

Thank you so much and yes they were under a bridge by water.  :)  Have a great weekend.

Dear Taylor,
This is a Giant Stonefly or Salmonfly in the genus
Pteronarcys, an insect generally found close to water as the nymphs are aquatic.

This is a Giant Stonefly in the genus Pteronarcys, and there are several possible species that are found along the eastern seaboard.  You can browse through the images on BugGuide for comparison.

Hi Bugman,
I found about ten of these clinging to the outside of my house at the end of February (unseasonably warm day). Can you help identify?
Thanks!

Stonefly

Stonefly

Dear jkayman,
This is a harmless Stonefly.  They are generally found not far from a stream or river.  Additionally, according to BugGuide:  “nymphs of most spp. develop in cool, well-oxygenated water and do not tolerate pollution; therefore, their presence is an indicator of good water quality, and their absence in areas where they previously occurred may indicate pollution.”

Thank you very much Daniel.  I do indeed live by a river.
Appreciate it.

I was working outside at a mill and we are situated along side the Fraser River. I always see strange bugs like the one pictured.
I’m trying to figure out what this insect is called.
I found it March 26th 2016( today)
The bug barely moved.I picked the bug up with a stick because the underside of his body was yellow. and I wanted to get a picture of it. The bug had a good grip.
I assumed it was just getting out of hibernation, as spring is upon us now.
I tried google image search, the result was dobsonfly, alderfly or fishfly.
Is this bug any of those three?

Dear Corinne,
Though it resembles a Dobsonfly, Alderfly or a Fishfly in the Order Megaloptera, your insect is actually a Giant Stonefly in the genus
Pteronarcys, commonly called a Salmonfly.  A comment posted to this BugGuide image indicates it is possibly the Ebony Salmonfly, Pteronarcys princeps, and the coloring matches your individual, but as the commentor indicates “two species here in CA and you need to see the naughty bits to tell them apart”, we cannot be certain of the species.  BugGuide lists British Columbia as a sighting location for the Ebony Salmonfly.
