Female Dobsonfly: First of the year

Caddisfly or Stonefly?
Hi Bugman,
I am a huge fan of bugs, and fully recognize their place in the world. My brothers were visiting family in Nova Scotia, Canada, and this bug attached itself to my brothers shoe. After searching around your page for a while I came up with two possibilities for identification, Caddisfly or Stonefly…..can you confirm if I’m right or not? Thanks so much!

Hi Marissa,
This is a female Dobsonfly, and our first submission of the year. Dobsonflies appear in May and June, though sightings do continue into the summer.
