Trypodendron lineatum

Striped ambrosia beetle

Description

The beetle is 2.5–4 mm long. It attacks languishing, weakened trees, cut down trunks and fresh stumps in forests situated in moist localities. It pushes small whitish wood debris out of galleries. It swarms in March and April. Mating takes place on the surface of the bark after which the females bore into the log to form galleries. The females lay eggs in a typical ladder-like gallery. It belongs to the so-called ambrosia beetles. The larvae need the fungus Trichosporium ferrugineum for their development. It grows inside the larval chambers, its hyphae and spores are a component of food for both larvae and adults. Widespread everywhere in coniferous forest in mountainous areas.
