 under side is very different; these are gray-brown, closely streaked 

 with fine, short lines. It is less common than P. comma, but its 

 habits are much the same. It is double-brooded, the first brood 

 appearing in early summer and the second in August and September. 

 The second brood hibernates. The caterpillar feeds on wild and 

 cultivated currant and gooseberry. The figure shows the under side.
