Lepidoptera The March Moth – Anisopteryx ascularia
This is another common moth, and should be looked for during March and April on the barks of trees in oak and other woods. The fore wings are of a dingy brown colour, paler near the base, and crossed by a pale wavy line. The hind wings are lighter, with a central dark spot. But this description applies to the male only, for the female is wingless, and may be known by the tuft of hair that tips the abdomen.
The caterpillar is pale green, clouded with a darker tint, and has a white line on each side of the back. It feeds in May on the three trees named for the last species, also on lime (Tilia vulgaris) and elm (Ulmus campestris).
