Your letter to the bugman:  This creature flew into my garage with very large wings, and a creepy looking head.  I have no idea what to class this insect as.  It looks vicious.  I hope the pictures help with identification.
Thanks,

Male Dobsonfly

Dear Michael,
Despite his large size and impressive mandibles, this male Dobsonfly is perfectly harmless.

Your letter to the bugman:  Hi!
This interesting creature was like looking through a microscope, only… I wasn’t.  This is a standard sized brick it is sitting on. Seen mid July on a very rainy day. There were several on the wall of the building. My guess after a bit of research would be Dobson fly?  Thank you!

Female Dobsonfly

Hi Jamie,
You are correct that this is a female Dobsonfly.  We posted numerous images yesterday of both Dobsonflies and related Fishflies, a clear indication the hottest days of summer have arrived.

Female Dobsonfly

Hi Alex,
We are being bombarded with identification requests for Corydalids today, but your image is the first we have received of a female Dobsonfly, and the image is so beautiful, we have to format it for posting.  Though the mandibles of the male Dobsonfly look much more frightening, they are specialized for allegedly fighting off other males as well as during mating, but they are not useful for either eating or defending from a threat.  The mandibles of the female Dobsonfly are much more utilitarian, and she can easily defend herself by painfully nipping at a threat, including a person, but the bite is not dangerous.  Adult Dobsonflies do not eat.

Hi Daniel,
Thanks for the quick response! Your website has created a whole new world of backyard research for me. I’ve been doing lots of reading on these guys since I saw your response.
Feel free to use my picture for anything that you might need.
Cheers,
Alex

Hi again Alex,
We are happy to hear our site has inspired you to do more research into the wonderful creatures that surround you.

Your letter to the bugman:  Hello there! My dad was watering our plants outside and I guess managed to (accidentally!) shoot this guy right out of the air. He’s certainly had his bell rung, I’m taking care of him and hoping to let him go soon 🙂 But I’d like to know what he is as I’ve never seen anything like this creature before, and he’s BIG! I managed to find something called an “antlion” which he looks most like. Is that correct?

California Fishfly

Dear McKinley,
This is not an Antlion.  It looks to us like a California Fishfly or Western Dobsonfly,
Neohermes californicus, which is pictured on BugGuide.  According to BugGuide:  “appear to prefer streams (Chauliodes prefer still water)”

Fishfly

Dear Miss Marci,
This is a Fishfly in the genus
Chauliodes, and because the antennae in your individual appear to be serrate, we are concluding that this is a female Spring Fishfly, which is pictured on BugGuide.  Despite being called a Spring Fishfly, there are Ontario sightings as late as September according to BugGuide data.

Male Dobsonfly

Dear Maggie,
This fierce looking male Dobsonfly is actually perfectly harmless.  Dobsonflies are among our most common summer insect identification requests.
