Warble fly exhibiting stalking attack- crawls though tundra to approach and attach itself to host.

The more common approach of airborne assault, is detectable by caribou, sending the animals into immediate retreat. Once attached to the host, the Warble Fly deposits eggs on the animal's fur. When hatched, the newly emerged larvae travel to the skin and burrow within the host. Inside of the caribou, the larvae migrate to the upper body region, remaining and feeding for the next year. The following summer, the mature Warble larve exit the caribou from breathing holes cut into the hide the previous fall.

We were on constant guard to remain observant and quickly remove these Warbles from our own persons. Contrary to established preconception, there does exist recent scientific documentation of Warble Fly infestation of a human.
