348 INSECTS INJURIOUS TO THE RED CURRANT. 



appears, of a brown color prettily ornamented with silvery 

 spots. After remaining in the pupal condition from one to 

 two weeks, the time varying with the heat of the weather, 

 the butterfly appears. 



There are two broods during the season, the Iarva3 of the 

 first one appearing late in June, those of the second maturing 

 early enough in the autumn to admit of the escape of the 

 butterfly before severe frost occurs. This insect rarely appears 

 in sufficient numbers to prove troublesome ; should it become 

 numerous, hellebore and water would no doubt prove an 

 efficient remedy, or the larvae might be subdued by hand- 

 picking. 



No. 210. The Currant Angerona. 

 Angerona crocataria (Fabr.). 



The moth from which this caterpillar is produced is usually 

 quite common, but the larva, although often found feeding on 

 currant leaves, feeds upon the gooseberry, strawberry, and other 

 plants besides, and hence is seldom sufficiently abundant on 



currant-bushes to attract much 

 attention. The accompanying 

 figure, 361, represents the larva 

 a little more than two-thirds 

 grown, feeding on a gooseberry 

 leaf. At this period it does 

 not differ materially from the 

 full-grown larva except in size. 



When mature, it is about an inch and a half long or more, 

 tapering towards the front. It is of a yellowish-green color, 

 with an indistinct whitish line down the back, and a rather 

 broad whitish streak on each side below the spiracles, bordered 

 above with faint purple, which increases in depth of color on 

 the hinder segments and becomes a purple stripe on the last 

 one. The spiracles are white, edged with purple; each seg- 

 ment of the body has its anterior portion swollen and yellow- 

 ish, and on most of the segments there are a few minute black 

 dots.
