Overlooked Cave Beetle
A rare troglobitic beetle that was long confused with related species before being formally described. It is known from very few cave localities.
Did You Know?
Its common name reflects that it was overlooked by scientists for decades.
Shaft Louse
A fast-moving louse found on the feather shafts of chickens and other poultry. It feeds primarily on feather barbs and can cause significant plumage damage.
Did You Know?
Shaft lice can run so quickly across feathers that they are difficult to catch even with practiced fingers during bird examinations.
