     Jochen Möhr reports from Metchosin this morning:

 

6 Eupithecias

2 Egira hiemalis

2 Hydriomena manzanita

1 Eupsilia tristigmata 

1 Phigalia plumogeraria

   Eupsilia tristigmata overwinters as an adult moth, and consequently can be seen either in late fall or early spring.  The caterpillar feeds on various plants (e.g. Rosa, Rubus, Geum, Salix)  –  and on other caterpillars!

    Jochen Möhr sends several pictures of moths from his Metchosin home yesterday and today, a few of which are shown here.  The Egira hiemalis and Phigalia plumogeraria are relatively easy, but Jochen has us all (Jochen, Libby Avis and myself, Jeremy Tatum) working hard over the pugs (Eupithecia) and highflyers (Hydriomena).  The two possible pugs are Eupithecia annulata and E. olivacea, and I don’t think any of us is willing or able to say with 100 percent certainty which they are, so I’ll label them either/or.  The typical early highflyer is Hydriomena nubilofasciata, and some of these have indeed appeared recently.  But some of Jochen’s recent highflyers are H. manzanita.  H. manzanita usually doesn’t appear quite so early in the year, and they are usually rather grey and without much colour.  Yet some of Jochen’s highflyers have appeared deceptively colouful – but the details of the patterns together with the characteristic wing-shape, or way of holding their wings, have shown that they are H. manzanita.  The caterpillars of H. nubilofasciata feed on Garry Oak, and the caterpillars of H.manzanita feed on Arbutus and – unsurprisingly! – on Manzanita.

    Jochen Möhr writes from Mechosin: This morning 16 Eupithecias, most out of reach of the camera, one E. hiemalis and one plume moth.  Jeremy Tatum writes:  I think the default Rumpel Taube-like plume moth here is probably Emmelina monodactyla, whose caterpillar can often be found inside the flowers of Calystegia.  There are several other plume moths locally, but they don’t look quite like this one.
