Eusattus dilatatus – dune darkling beetle (Tenebrionidae)
Sand dunes are an unusual habitat, and the creatures found on them are equally odd. One of the more charismatic dune endemics is Eusattus dilatatus, a large darkling beetle found in southern California. This scavenging insect has long legs for digging and a waxy cuticle to prevent dessication.
Eusattus is not the easiest photographic subject. It seemed uncomfortable out in the open and would burrow as soon as I placed it on the sand. The series below spans 30 seconds.
**update** Tenebrionid expert Kojun Kanda corrects the identification from E. muricatus to E. dilatatus.
