Your letter to the bugman:  Saw this guy outside of my office. He’s about 6 inches long and got pretty aggressive when we tried to move him out of the path.

Male Dobsonfly

Dear Kat,
This impressive guy is a male Dobsonfly, and though his immense mandibles look dangerous, they are quite useless when it comes to biting humans.  The female Dobsonfly has more utilitarian mouthparts, and though she has much less impressive looking mandibles, they are actually capable of giving a significant, though perfectly harmless pinch.

Female Dobsonfly

Dear Bragg7,
Moths that feed as adults have a sucking proboscis for a mouth.  Your critter has impressive mandibles.  This is a female Dobsonfly, one of our most common identification requests during summer months.

Your letter to the bugman:  Hi! I have lived here my whole life and have never seen anything like this. From a distance I thought it was a brown praying mantis or a huge leaf insect/moth, but it is not and I Am Scared. Thanks!!

Female Dobsonfly

Dear Liz,
This is a female Dobsonfly, and though her mandibles might produce a painful pinch, she is harmless.  In the interest of your mental well-being and your ability to sleep peacefully at night, we believe you should be thankful you did not encounter a male Dobsonfly, though his mandibles are all for show.

Fishfly

Dear Richard,
This is a Fishfly in the genus
Chauliodes.  According to BugGuide:  ” Larvae leave the water to pupate under bark or in rotting wood; pupal period takes ~10 days. Adults live a week or less. Eggs are laid in masses on vegetation near water. Larvae hatch and crawl to water.”

Daniel,
Thanks so much for ID’ing the Fish Fly for me. First one I remember ever seeing. Quite a treat to look at too.
I especially was impressed by its size and its antennae.
Thanks again,
Rich

Female Dobsonfly

Dear Jungle Life,
This is a female Dobsonfly.  Dobsonflies are considered harmless, though females have powerful mandibles, and they might nip if they feel the need to defend themselves.
