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.
Congo Floor Maggot Fly
A yellowish-brown blow fly whose larvae are unique among Diptera in being temporary ectoparasites that feed on sleeping humans. Larvae live in the dirt floors of huts and emerge at night to feed on the blood of sleeping people, then retreat into the floor. Adults do not bite.
Did You Know?
It is the only known fly whose larvae feed on human blood like a bedbug, making it a unique case of larval hematophagy.
