Giant Caddisfly, 3:06pm - Phryganea
Ma-Me-O Beach, Alberta, Canada
July 20, 2008
Size: Giant
There was many wing remains of this insect in spiders webs. The pattern and large size almost made me think we had some Owlflies or Antlions in the area..

This one was barely alive as well..

Phryganea cinerea
Borealfacon-

I believe your caddisfly to be of family Phryganeidae (Giant Casemakers), genus Phryganea, species P. cinerea, as I believe that to be the only one found in Alberta.

It's helpful living in a place
where there is only one of its genus.

Thanks, what sort of insects would attack these sorts and make them end up like this?

Hard to say
Borealfalcon-

It depends on whether this happened before or after the caddisflies got caught in the spider webs. If it happened before, I would tend to suspect dragonflies, which are notorious for their airborne insect dissection habits. However, is does seem a bit unlikely that multiple caddisflies would fall from the air, post-dissection, and just happen to land in a spiderweb.
