The adult grappletail (Octogomphus specularis), a type of clubtail dragonfly, will eat almost any soft-bodied insect – including mosquitoes, flying ants, termites, small moths, flies, damselflies and even other dragonflies.
Grappletails were actively feeding one morning as I wandered along Ash Creek below the Lower Campground (Lassen County CA). The menu included what appeared to be flying ants and damselflies belonging to the pond damsel group. It was fascinating to watch these yellow and black dragonflies catch and devour their prey.
More information about the grappletail can be found in my earlier post “Grappletail” 10-09-13.
