White-barred Clearwing Synanthedon spheciformis

([Denis & Schiffermüller], 1775)

---

Wingspan 26-31 mm.

Locally distributed in south-east and north-west England and parts of Wales, this distinctive clearwing has creamy patches near the tips of the antenna and similarly coloured bands on the tegulae and the second abdominal segment.

It flies in June and can be attracted by the use of pheromones in suitable areas.

The larvae feed on birch (Betula) and alder (Alnus), burrowing into the wood and remaining in this stage for two or possibly three years.
