   The caterpillar of Behrensia conchiformis is exceedingly well disguised and very difficult indeed to detect.  But that is as nothing compared with its cocoon.  The cocoon is made on treebark and incorporates bits of bark, making it, to all intents and purposes, invisible.  It is shown below.  If I can summon up enough computer skills (doubtful), I’ll try and show the photograph again tomorrow, indicating exactly where the cocoon is – though even when indicated, it may not help you.  Jeremy Tatum

 

  The caterpillars of all three moths in today’s posting fed on Snowberry.  Euceratia exclusively so; the other two have alternative foodplants.
