An insect nymph traverses the head of a cutleaf daisy (Erigeron compositus). May 21, 2013.

daisy (Erigeron compositus). May 21, 2013. A Rocky Mountain clearwing moth (Hemaris thetis) visits snowberry bushes in the northern floodplain. The species lives in mountainous areas near streams and meadows. Larval host plants include snowberry species (Symphoricarpos) and other members of the honeysuckle family (Schmidt 2009). Reference: Schmidt, B.C. 2009. Hemaris thetis (Boisduval, 1855) (Sphingidae) is a distinct species. Journal of the Lepidopterists’ Society. 63(2), 2009, 100-109.

Thin-leaved owl clover (Orthocarpus tenuifolius) attracts pollinators with vivid colors but has little forage value for wildlife. A single yellow flower towers above pink bracts and other less conspicuous flowers. July 31, 2013.

Ants swarm on big sagebrush, farming black aphids for their honeydew. July 30, 2013.

Fields of yampah (Perideridia gairdneri) bloom in moist meadows and open slopes during late July and August. Pollinators swarm to their short-lived flowers.

Adult bee-flies deposit eggs in the nests of ground-nesting bees. In these nests, bee-fly larvae feed on pollen and other stores, then eat the bee larvae in the nest after they hatch (Moisset).
