Two-banded Longhorn
A robust, short-antennated flower longhorn with two yellowish bands on dark elytra. Common across European forests, adults appear very early in spring and are among the first beetles active. Larvae develop under bark of dead conifers.
Did You Know?
Larvae create a characteristic oval pupal chamber under bark, lined with coarse wood fibers that insulate against cold.
Nairobi Eye Beetle
A small, brightly colored rove beetle with an orange and black body that produces pederin, a potent blistering toxin. Outbreaks near human habitation cause painful dermatitis known as Nairobi eye.
Did You Know?
Pederin, the toxin in its hemolymph, is 12 times more potent than cobra venom drop for drop and is being researched as an anti-cancer compound.
