legs yellowish. 
All on Spiraea ulmaria spinning together the young (undeveloped) 
leaves, and living between them, often gnawing the young mid-rib, so 
as to cause the upper part of the leaf to dry up. Feeding up in the 
undeveloped tops, but quitting them when full-fed, to spin up among 
rubbish, or under the turned down edge of a dead leaf. Pupa light 
brow n ; moth emerging from the middle to the end of July. I am not
