of the Goat Moth feeds on the internal substanceof willow trees; it is said to be also found in the body of the oak, butwe have never discovered any in such a situation. The eggs are laidin the crevices of the trees ; as soon as the Caterpillars are hatched,they begin to pierce into the solid wood. In most parts of Englandthey are called Auger Worms; the holes which they make in thetimber appearing as if bored with that Instrument.
It lives in the Caterpillar state three years before it is transformedto a pupa; when full fed it is four inches long, the body appearsvery fleshy, and without hairs; the head is black, and armed with verysharp forceps; the cafe is composed of bits of wood and saw-dust,which it unites with a strong web ; the inside is lined with a finesmooth white filmy substance, like sattin; it pastes to the pupa state inthe cavity which it has perforated in the caterpillar state, within threeor four inches of the opening: it remains only two months in thatstate before the Fly is produced.
Is found in chrysalis in May; in the fly state, the latter end of June,er in July.
