Hi there.
My friend saw this bug while out walking and was wondering what exactly it is. I think it looks like some sort of earwig or mantis but I honestly have no idea. It has six legs, medium-long antenna at the back and short ones at the front, black and white with stripes on its back and it doesn’t appear to have wings. It’s currently Summer and I believe it was around the Bracklinn Falls area in Callander.

Stonefly Exuvia

Dear Lauren,
We are surmising that Bracklinn Falls means a waterfall on a stream or river.  This is the exuvia or cast-off exoskeleton of a Stonefly, an aquatic nymph that eventually develops into a winged adult.  Here is a FlickR image of a Scottish Stonefly nymph and here is an image of an adult Stonefly from Encyclopedia of Life.

This bug was on my pillow on Wednesday the 5th of May….a bit after a biblical 3 days straight downpour in Fredericksburg Virginia…It was on my pillow above my ear ……………………..
I think it was bigger than an an inch but smaller than an inch and a half.
I’d really like to know what it was…………

Stonefly

Dear Susan,
This is some species of Stonefly in the order Plectoptera.  We wish you had been able to attach an in focus image of the entire insect as that would help us with identification.  This BugGuide image of a member of the genus
Isoperia, and this BugGuide image of Taenionema atlanticum both look similar to your individual.  Do you live near a stream or river?  The larvae of Stoneflies are aquatic, and they are f0und in fresh water.

Stonefly

the photo in BugGuide looks exactly like the fellow on my pillow….thanx.  I live near the Rappahanock River hence a freshwater source.  I have hand tremors and now have real trouble getting a well focused photograph…. but now it’s hard to get an in focus shot. Curses!

Found these crawling all over my house today. I live just south of Boston. There were tons of them, about a half inch long excluding antennae.

Small Winter Stonefly

Dear Hoping it’s harmless,
It is.  This is a Small Winter Stonefly in the family Capniidae.  According to BugGuide:  “adults emerge from November to June (most common in winter and early spring).”  Do you live near a stream?  According to BugGuide:  “nymphs beneath rocks and gravel on the bottom of streams and rivers; adults often seen on snow, or resting on concrete bridges over streams.”  Since they are only found near very clean, well oxygenated water, their presence is a sign that the local water is not polluted.

American Salmonfly

Dear Ken,
This is a Giant Stonefly in the genus
Pteronarcys, and based on your location and this image on BugGuide, we believe it is the American Salmonfly, Pteronarcys dorsata.

Hello,
I moved to northeastern PA in December. Our snow finally melted and I decided to go out to explore today. I found a shell of a bug that I can’t seem to find an identity for. It looks like it had a stinger on the end. I haven’t successfully found what this bug may have been.
Please help!
Thank you!

Naiad Exuvia

Please provide additional information.  What size and what type of habitat?

Thank you for your reply.  This was found on a bridge above a creek.  It is about 1.5 inches from eyes to the end of it’s tail.
Thank you,
Laura
Thanks for the additional information Laura.
This is the exuvia or cast-off exoskeleton of an aquatic nymph or naiad, but we are not certain of its exact identity.  Because of the look of the antennae, our hunch is that it might be the Exuvia of a Stonefly Naiad in the order Plecoptera, perhaps something similar to the naiad in this BugGuide image.

Winter Stonefly

Dear Kitty,
Congratulations on having a population of Winter Stoneflies at your house because it is our understanding that the aquatic nymphs can only survive in clean, unpolluted water.  According to BugGuide:  “adults emerge from November to June (most common in winter and early spring).”
