Nectaring on Butterflybush at a friend's house (thanks, Jewel!) Tiny: typical wingspan is <3 cm (~1"). Butterflybush is somewhat atypical for this species, but I guess it was too good to resist! from www.butterfliesandmoths.org/
: "Caterpillar hosts: Many plants in the pea family including yellow sweet clover (Melilotus officinalis), alfalfa (Medicago sativa); various species of vetch (Vicia), clover (Trifolium), wild pea (Lathyrus), and bush clover (Lespedeza); and others. Adult food: This butterfly has a low flight and a short proboscis, thus is found at flowers close to the ground which are open or short-tubed. These include white sweet clover, shepherd's needle, wild strawberry, winter cress, cinquefoils, asters, and others."
