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.

Summer Fishfly

Dear Bug watcher in CT,
This is a Summer Fishfly, and in the past 24 hours, we posted another image of a Summer Fishfly from Connecticut.

From what other people have said via facebook agricultural pages, mine was a female Dobson Fly. They say that they are similar…? Anyway, I have seen that the males have very large mandible, larger than this one.

Same family.  Different species.  Female Dobsonfly has very different antennae.  See BugGuide.

Cool, thanks! Insects have always been fascinating to me. It astonishes me how many different varieties there are that some people will never see in their lives.
