Bordered Great Diving Beetle
A large British diving beetle similar to D. marginalis but with expanded yellow margins. It prefers larger, more permanent water bodies.
Did You Know?
Females have deeply grooved elytra while males have smooth ones, making the sexes easy to distinguish.
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.
