Dear Bugman,
This photo was taken last year at a river in Maine. Our family is fascinated by all creatures, great and small. So I was thrilled to be lucky enough to come across this Mama laying her eggs.

Dear Cartwrights,
Your images are awesome, however we need to make a slight correction.  This is not a Dobsonfly.  This is a closely related Dark Fishfly in the genus
Nigronia.  According to BugGuide:  “Emergence of adults may be synchronized. Adults are diurnal (seen flying near streams) and also nocturnal, so come to lights. Eggs are laid on the underside of vegetation overhanging a stream. Larvae are aquatic, predatory. Perhaps take three years to mature in more temperate areas, such as West Virginia. Pupation occurs in earthen cells on the edge of streams.”  Your images illustrate an option to laying eggs on vegetation.
