Simulated Jewel Beetle

A small jewel beetle with variable yellow and black banded patterning on its elytra. It is found in eucalypt habitats across southern and western Australia.

💡

Did You Know?

Its color pattern closely mimics that of unrelated wasp species to deter predators.

Patagonian Darkling Beetle

A flightless darkling beetle endemic to Patagonian steppe habitats, with a rounded, heavily ridged black exoskeleton. It is adapted to the harsh, windy conditions of southern Argentina, sheltering under stones and shrubs during the day. It is an important detritivore in this arid ecosystem.

💡

Did You Know?

Its heavily ridged elytra are fused shut, making it flightless but providing excellent protection against desiccation in Patagonia's dry winds.
