This pretty insect on our goldenrod caught my eye awhile ago. It's a black-and-yellow lichen moth (Lycomorpha pholus). Yellow? This one was definitely REDDISH ORANGE.
Bugguide.net says this about the species: "Larvae feed on lichens. The strictly diurnal adults are often found on flowers of dogbane (Adpocynum, Apocynaceae), goldenbush (Ericameria, Asteraceae) and goldenrod (Solidago, Asteraceae).....The red color pattern is thought to be mimicry of poisonous Lycid beetles, such as Calopteron."
