Types of Behavioral Activity Demonstrated by the Great Sand Dunes Tiger Beetle

Activity

 

Description

Behavior

Basking

 

Beetles exhibit relatively slow movements and hold their abdomens close to sand surface for warmth.

Basking

Foraging and Searching

 

This is a general term for adults actively in search of prey, or searching for mates if the season is appropriate.

Foraging and searching

Stilting

 

Adults continue to forage or search, but in a stilted position, in which the beetle straightens its legs to push its abdomen as far off the sand as possible, to keep the insect from overheating.

 

Stilting

Shade-seeking

 

Adults seek shaded areas for protection from heat.

Shade-seeking

Daytime-burrowing

 

Adults construct temporary shallow burrows during the hottest hours of the day.

Burrowing

Evening-burrowing

 

Adults construct shallow burrows during later, cooler hours of the day and remain in them throughout the night.
