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).”

Hi, we have swarms of these bugs in the snow around our house. My kids and I have scoured the internet, but we can’t find any information to identify them. My kids were so excited to have of our pictures featured on your site years ago when they were little of a cicada killer. Please help us again!! Thank you!

Snowfly

Dear Lundy Family,
We are thrilled to post your image of a Snowfly or Small Winter Stonefly in the family Capniidae, the first of the season, though we did just create our Snow Bugs tag for creatures active in winter months.  According to BugGuide:  “adults often seen on snow, or resting on concrete bridges over streams.”  We suspect you are not in an industrial part of Michigan because Stonefly larvae are aquatic and they are generally only found in moving water like streams that are not polluted.

Cool, we are in the country, and have a large creek flowing through our property.  Thanks!
