Lepidoptera The Bordered White Moth – Bupalus Piniaria
The male of this species is boldly marked with yellowish white and dark brown, the arrangement of the two colours being shown in fig. 190. The female is very different in general appearance. Her wings are of an almost uniform orange or yellowish-brown tint. The fore wings are darker near the tip, and there is generally a darker transverse band across the centre.
The male may often be seen flying in the sunshine among the branches of fir trees during May and June, but his mate is rather less active, and is generally to be secured by beating the branches.
The caterpillar is pale green, with whitish stripes and yellow spiracles. It feeds during August and September on the leaves of the Scotch fir (Pinus sylvestris).
