Dotted Bee Fly
A spring-flying bee fly distinguished from its commoner relative by spotted wings and a darker fur coat. Its larvae parasitize mining bee larvae of the genus Andrena.
Did You Know?
It appears only in spring for a few weeks, closely tracking the flight season of its specific Andrena bee hosts.
Secondary Screwworm Fly
A blow fly that breeds in carrion and occasionally infests wounds in livestock. It is widely used in forensic studies in the Americas.
Did You Know?
Unlike the primary screwworm, it only feeds on dead tissue rather than living flesh.
