Window Fly
A small shiny black fly often found on windowsills inside buildings. Its larvae are beneficial predators of carpet beetle and clothes moth larvae.
Did You Know?
Despite being found indoors, it is actually beneficial because its larvae eat destructive carpet beetles.
Common Clubtail
A medium-sized dragonfly with a club-shaped abdomen tip and distinctive yellow and black markings. It emerges en masse from rivers in late spring.
Did You Know?
Unlike most dragonflies, clubtails frequently perch on the ground or on flat surfaces rather than hanging from vegetation.
