Ok, I've found some crazy critters move into my aquariums but this one has me stumped.
Dragonfly larvae
Somebody must have thrown this in recently because the tank is indoors with a lid that is almost perfectly sealed.

I know that hitch hiking is almost impossible because my tank hasn't had anything added since I nuked a yellow fish grub infestation nearly a month ago.
