Are you a sun worshiper or are you UMBRIPHILOUS?

What's "the word I'm thinking of"? Today it's....

UMBRIPHILOUS [UM-bruh-FILE-us] (adjective)

Fond of shade

"Being umbriphilous, he may frequently be seen siting on the trunks of trees, or on the shady side of houses, etc., as he rests during the day, and flies only after dusk, often being attracted by light." --Clarence M. Weed, "Two Shade Tree Pests" (1895) (slightly edited)

Summer is coming. Don't forget this word in the hot sun.
