Tundra Blow Fly

A metallic dark blue blow fly common across Arctic and subarctic regions. It is one of the first flies to become active in spring. Adults are attracted to carrion and can detect dead animals from great distances.

💡

Did You Know?

This fly is so cold-tolerant that it is used in forensic entomology to determine time of death in cold climates where other blow flies cannot survive.

Sexton Beetle

A black and orange carrion beetle that buries small animal carcasses as food for its larvae. Both parents care for the brood.

Parents feed their larvae by regurgitating pre-digested carrion, similar to bird feeding behavior.
