Distribution and habitat

Occurs in the sand dunes of the Namib Desert.

Behaviour

Leucorchestris arenicola is known to do a dance, hence its common name. The purpose of this dance is to communicate to other males or females by drumming the tarsae against the sand.

The retreat consists of a short wide silk lined burrow at the base of dunes. This, 30–40 cm long burrow, is dug at an angle of 30 degrees and approximately 25 cm deep where temperature is more tolerable than on the hot day time surface temperatures. A camouflaged trapdoor covers the burrow. Females only wander no further than 40 m from their burrows while males have been found to do a round trip of approximately 810 m. When returning they use various methods of navigation to directly via the shortist route to its burrow.

Ecological interactions

Tenebrionid beetles, spiders, scorpions and Dune geckos, Pachydactylus rangeri are the main prey Leucorchestris.

Derivation of name

Leucorchestris is derived from the Greek orchestris meaning feminine dancer, and leuc referring to the spider’s white colour.
