East African Oil Beetle
A large, dark blue-black beetle with a soft, swollen abdomen and short wing covers. It oozes oily orange hemolymph containing cantharidin when disturbed.
Did You Know?
Its larvae undergo hypermetamorphosis, changing body form dramatically through their development as they transition from active hunters to sedentary parasites.
Douglas-fir Beetle
A dark reddish-brown bark beetle that attacks Douglas-fir trees, particularly those weakened by drought or windthrow. It is among the most damaging bark beetles in the Pacific Northwest.
Did You Know?
It preferentially attacks fallen or stressed trees, but during outbreaks it can kill large numbers of healthy standing trees.
