Japanese Hotaruko Firefly
A large terrestrial firefly with a dark brown body and bright reddish pronotum. The wingless, larviform females produce a bright sustained glow from the ground to attract flying males.
Did You Know?
The Japanese name 'hotaruko' distinguishes these terrestrial glowworm-type fireflies from the aquatic 'hotaru' species.
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.
