    Jeremy Tatum writes:  Butterflies are not quite back yet (though if the current mild weather continues there is always a chance of a Mourning Cloak or a Satyr Comma).  In the meanwhile, Bill Katz has photographed an American Tissue Moth at Goldstream Park. The caterpillar of this moth is a specialized feeder, feeding exclusively, as far as I know, on Cascara.  He also reports a recent sighting, from his Summit Hill home, of an early Drepanulatrix moth.  We’d be interested in all photographs of moths of this genus –  at present we are not certain which species we have here.  Their caterpillars, too, are specialists, feeding mostly on Ceanothus.
