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.

Your letter to the bugman:  Hi there! I’ve always enjoyed your site, and thought you might enjoy these photos from a video of a dobsonfly pupa in my garden (if you would like the video, I’m happy to share – just email me). I noticed it moving after watering the plants. I’ve never seen the pupal forms before (just larvae and adults most years) and wasn’t sure at first what was going on. But it seems to be re-packing the cell it made in the soil. Once it seemed to be finished, I placed a small bit of birch bark over the hole for a bit more cover. We live near a river in a woodland area, and this year had quite a number of hellgrammites emerge one day in the spring – 20 that we could see!

Dobsonfly Pupa, or pre-pupal Hellgrammite???

Dear Erin,
Thanks for sending in your images along with personal observations.  While we don’t contest that this is an immature Dobsonfly, we question perhaps that it might be a pre-pupal Hellgrammite that is preparing for metamorphosis rather than an actual Dobsonfly pupa.

Your letter to the bugman:  My gf screamed and pointed at this monstrosity on the side of a building. I’d never seen anything like it before but weird bugs tend to show up during the summer around here. We’re just left wondering what it is and (mainly for my girlfriend) is it gonna kill us?

Your letter to the bugman:  I was fishing a larger river and went up to the road and noticed these bugs all over the place. They were smashed on the road and were trying to cross the road, from river bank to cornfield and vise versa. The bugs were between 3 and 7 inches long.

Hellgrammite

Hi Joey,
Did you catch many fish?  If not, nature provided you with an excellent bounty to change your luck.  The Hellgrammite, the larval form of the Dobsonfly, is a prized bait among freshwater anglers.

I knew they looked like hellgramites, but I didnt know they ventured out of the water like they did. Cool thank you for the quick reply.

We believe they leave the water to pupate.
