Anthrax irroratus
Spotted Bee Fly
Anthrax irroratus is a bee fly (family Bombyliidae) widespread across North America, ranging from Alaska and northern Canada to Central America and the Caribbean. Adults are pollinators that frequent flowers, while larvae are parasitoids of solitary bees and wasps in at least five families. The species is one of numerous bee flies that exploit ground-nesting Hymenoptera as hosts.

Aulogymnus
Aulogymnus is a genus of chalcidoid wasps in the family Eulophidae, first described by Förster in 1851. Members of this genus are small parasitoid wasps, part of a diverse family that primarily parasitizes other insects. The genus has been recorded from Europe and Asia. Specific biological details for the genus as a whole remain poorly documented in accessible literature.

Boreus reductus
Snow scorpionfly
Boreus reductus is a wingless species of snow scorpionfly in the family Boreidae, order Mecoptera. Adults are active during winter months and can be observed hopping across snow and ice. Unlike many Mecoptera, this species lacks functional wings entirely. Adults and larvae feed on mosses and liverworts. Males possess enlarged, upward-curving genitalia that resemble a scorpion's stinger, giving the group its common name. The species engages in a distinctive mating behavior where males carry females on their backs.
