White-faced Meadowhawk

Like the Band-winged Meadowhawk in my last post, this White-faced Meadowhawk is also trying to reduce heat stress.  His strategy is to throw his wings forward and down, thereby shielding his thorax from the sun's rays.  Because his transparent wings do not cast much of a shadow, this strategy may involve reflecting light from the body (Mead 2003).  The White-faced Meadowhawk is not new for my list, as I first found it when I began my dragonfly quest last August in Erika's garden.
