Like other "clearwing" moths, the Raspberry Clearwing is day-flying and designed to look like a wasp for protection.
The upper wing is not actually "clear" but has a pattern of scales.
These are laying their eggs on raspberry leaves; the ovipositor can be seen in action.
Although common on raspberries in continental Europe, this moth has only relatively recently (2007) colonised the southeastern UK,
larvae being imported on raspberry plants. Larvae are white with a black head and spend two winters in raspberry (sometimes blackberry) stems and roots,
making a gall on the stem before emerging.
The adult flies in July-August (UK; Jun-Aug in Eurasia). Wingspan is 22-32mm. There are some 6-7 yellow bands
visible on the body and a yellow fan tail.
