I personally have not seen this bug, but I just recently had a friend describe how his family and himself found a ton of these hanging out by their parents house in Clayton Washington. He described it to me, saying that he was actually quite a bit scared about it. While I thought his mysterious bug was interesting, I more or less brushed it off. Then this afternoon, I had several friends talk about some weird bug they saw and one actually posted a picture of it (picture I included). I know absolutely nothing about the bug other than it’s in eastern Washington, was chilling outside, and that it’s freakier than a Parlomont bassline. Help would be much appreciated.

What's That Exuvia

Stonefly Exuvia

Hi Eric,
This is the exuvia or cast off exoskeleton of an insect that has undergone metamorphosis.  We believe it is a member of the order Orthoptera.  We will do additional research and attempt to identify the species.

Update
Thanks to several comments, we realize that this is actually a Stonefly Exuvia from the order Plecoptera.  Immature Stoneflies or Naiads are aquatic insects that mature into winged Stoneflies, so the exuvia are generally found in close proximity to bodies of water.

I’m very interested on what type of bug this is. I have never run across one like this… Photo was taken 5/5/14 around 9 am. I’m not sure if it native to the area or possibly an invasive species.

There are at least a dozen of these bugs hanging out on my front porch.. and they love to hitch a ride indoors by falling/jumping onto my clothes as I walk through the door. What are they?

Stonefly

Winter Stonefly

Dear Randi,
This is a Stonefly in the order Plecoptera, and it looks very similar to the Winter Stonefly in the genus
Taeniopteryx that is pictured on BugGuide.  The nymphs are aquatic, and 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,” so you must have clean, unpolluted water nearby.

Hi there,
In April 2013, we were sitting under a bridge by the river, when we noticed these guys all over the wall. They were about 5 cm long and didn’t move much (we however found we moved very quickly).
Thanks!

Stonefly Exuvia

Stonefly Exuvia

This is the exuvia of a Stonefly, a flying insect that spends its immature development as an aquatic naiad.  When maturity approaches, the naiad leaves the water and molts for the last time, emerging as a winged adult Stonefly.  Here is an image of a similar looking Stonefly Exuvia from BugGuide.
