[3] Adult rain beetles lack functioning mouthparts and are unable to feed.

[5] Rain beetles spend most of their lives as larvae underground, burrowing up to twelve feet below the surface.

As the females are flightless, the males spend a large portion of time walking on snow in search of them.

[7] The male's ability to maintain a high internal temperature, up to 95 degrees, is critical to their mating and survival prospects, as their thoracic pile is ineffective insulation.

The males live only a few days, expending most of their energy in search of mates, while the females can survive a few months in their burrow.
