Grey tree frogs and Cope’s grey tree frog do frequent trees and may live far from ponds and lakes. These frogs are camouflaged to look like lichen-covered bark and blend really well with arboreal surroundings. There are several reasons tree frogs branched out from their aquatic ancestors: fewer competitors for insect prey and perhaps fewer predators (larger frogs and several snakes are known to eat small frogs). Unlike many tropical species, grey tree frogs return to the ground each spring to lay eggs in ponds and ditches – they are far easier to find and catch at this time.
Bees, like most insects, don’t have muscles directly connected to their wings. Instead, the flight muscles are attached to the roof wall of the thorax
