As the leaves grow larger, on what but a very few weeks ago were naked 

 branches, the little wriggling Tortricina larvse make their appearance, and roll 

 them up or fasten them together with silken threads, and so make for them- 

 selves snug habitations. Some of my readers may not, perhaps, have yet 

 taken up the study of the Tortrices, but by way of inciting them to do so, 

 and at the same time affording them some assistance in this rather difficult 

 group, I will briefly mention some of the larvae we may expect to find this 

 month. 



Every one who has a garden of his own, or access to a garden or orchard 

 of some one else's, must have noticed the bluish-green black-spotted wriggling 

 caterpillars, living between united plum and other leaves ; these are the 

 larvae of Tortrix ribeana. The dark olive-green white-spotted caterpillars, 

 feeding between united leaves of lilac and most other trees — garden or other- 

 wise — produce Tortrix rosana. These last have brownish heads, while those 

 of ribeana have either black or green ones. The greenish-grey larvae of 

 Batodes augustiorana with green heads, and the brown black-headed larvae of 

 Spilonota ocellana, also feed in May on a variety of trees. 



The little yellow caterpillars with pale brown heads we find this month 

 feeding between united leaves of apple, rose, and other trees, are the earlier 

 stage of Bidyopteryx holmiana and the dull olive green black-spotted ones, 

 with black heads, we see on hawthorn and sloe are the larvae of Penthina 

 cynosbana. The dark red brown black-headed caterpillars we sometimes find 

 in the south of England feeding between folded willow leaves, produce 

 AntitJiesia salicana, and the pale yellow (also black headed) larvae, uniting 

 willow or sallow leaves, are those of Eypermecia augustana. 



The bright green larvae of Penthina capraana feed on the shoots of sallow, 

 and those of Ditula semifasciana on the shoots and catkins. Those of 

 PeniJiina picana ;ilso feed on the sallow catkins.
