The situations where it is found are in gardens, chiefly 
on and about currant trees. 
The date of the appearance of the perfect insect is 
in June. June 5. 
The caterpillar is of a dull white colour, with a dark 
line along the back, the head light brown. 
The dates of the appearance of the caterpillar are in 
April and May; also, I believe, in October. 
It feeds on the pith of the currant tree. 
This is the commonest of our British species of the
