Venusia obsoleta (Lep.: Geometridae)  Jochen Möhr

Drepanulatrix monicaria/secundaria (Lep.: Geometridae)  Jochen Möhr


   The caterpillars of at least one of these Drepanulatrix species (whichever it is!) feed on Ceanothus thyrsiflora.


Udea profundalis (Lep.: Crambidae)  Jochen Möhr


The caterpillars probably feed on a variety of plants.  They can be a pest of Celery, although here they often feed on Stinging Nettle.
