Subarctic Flesh Fly

A medium-sized gray fly with black longitudinal stripes on the thorax and a checkered abdomen. Unlike most flies, females give birth to live larvae rather than laying eggs. Adults are found on carrion and dung.

💡

Did You Know?

By giving birth to live larvae that are ready to feed immediately, this fly gives its offspring a head start in the short Arctic summer.

Blood Bee

A cleptoparasitic bee with a bright red abdomen and black head that attacks the nests of furrow bees. Females enter host nests to lay eggs that hatch and consume the host provisions.

💡

Did You Know?

Its blood-red abdomen is the source of its common name and makes it look more like a ruby-colored ant than a bee.
