Seeking more info on Dobsonflies #874994

Asked June 27, 2024, 3:08 PM EDT

I believe this is a Dobsonfly. Are they harmful to humans, animals, or gardens/landscaping? Is seeing one indicative of others being nearby? I’ve never seen one before. Are they migratory? Where can they typically be found? How can I repel them without using harmful chemicals? Photos taken on 6/27/2024 in Albion, MI

Expert Response

Hello Meena,

That certainly looks like a Dobsonfly. Dobsonflies are not dangerous. They are an important part of the ecosystem, in that their larvae feed on small animals and the adults are eaten by birds and bats. A bite from their pincers can be irritating.
