No idea what kind of insect this is but it is on our front porch with some of its friends. Any insight would be helpful. Thanks!

California Dobsonfly

Dear Heather,
We are quite confident, because of the moniliform or beadlike antennae, this is
Neohermes californicus based on this BugGuide image.  BugGuide does not provide a common name, but Charles Hogue, in his awesome book Insects of the Los Angeles Basin, calls this a California Dobsonfly.

Hi Bugman,
We saw this bug crawling around on a rooftop bar last night. It apparently had been hanging around on the umbrellas and plants.
Any idea what it is? It looks prehistoric. Very cool.

Female Dobsonfly

Dear Amanda,
The mandibles on this female Dobsonfly are indeed quite impressive, and she defends herself quite well with them if she feels threatened.  The male Dobsonfly, on the other hand, has impressively large mandibles that are not really functional.  He uses them to battle other males and to impress female Dobsonflies during mating.

My husband found this bug just hanging out on a rag he had set on the back porch by our garage. I’ve googled “flying bug that looks like bark”. Looked at images…etc. I am not a bug expert, it’s hard for me to tell what this is, and I can’t find my insect identifier book. Can you help? Seems it’d be easy for someone with some knowledge. 🙂

Western Dobsonfly

Dear Laura,
This is really a wonderful image of NOT a Beetle, but rather a Fishfly, which we identified as
Neohermes californicus on BugGuide.  Charles Hogue calls this species the Western Dobsonfly.

I’ve been trying to ID this insect since I first saw it 3 years ago. I see them from time to time in my backyard (usually near pool). I live in Warwick, NY.
It’s a very unusual bug, very similar to both wasp and stonefly. It’s large, about 3 cm in length and to my surprise has huge wings which are not visible when folded. It’s head looks scary with large mandibles and very short antennae. Today I found a dead one in my garage with it’s wings fully spread. Everyone who I showed it to, had instant panic like reaction 🙂
I’m hoping you can help me to ID this insect.

Female Dobsonfly

Dear Len,
This is a female Dobsonfly, and though they are not aggressive towards humans, they can defend themselves with those powerful mandibles.  Interestingly, male Dobsonflies have incredibly developed mandibles, but they are incapable of biting with them.

Fascinating!
Thank you so much!
Yes I can see now it’s a dobsonfly, no doubt.
Looks like most of those that I observed were nymphs. Short antennas, no visible wings (like in pictures), but then one of them completely surprised me when it just took off and flew 🙂
Len.
