 Ian Cooper recounts a little adventure he had with a wasp:  A wasp landed on my hand while I was in the kitchen a couple days ago. After my initial surprise, I managed to capture it in a jar with air holes in the lid and gave it a slice of apple to dine on. I then brought it along on yesterday’s pre-dawn photo shoot at Colquitz and View Royal and released it on to some flowers by the E&N Trail in Esquimalt once the sun was up on my way back into Victoria.

   First report this year of a Cabbage White – one flew across the highway today when Val George was driving through Duncan.

 

If you look at the Full Moon at around midnight tonight Sunday/Monday, +/- 30 minutes or so, you may notice a faint shadow across its face, not very obvious.  The Moon is in the faint outer shadow (penumbra) of Earth.  This is a penumbral eclipse of the Moon.    If you were on the Moon, you would see a partial (not total) eclipse of the Sun by Earth.

   Jochen Möhr sends a photograph of a geometrid moth from Metchosin.  We have previously labelled this moth Venusia obsoleta/pearsalli, because we have been unable to distinguish between these two similar species.   Somewhat unexpectedly, Venusia obsoleta  has now been moved to another genus, and is now Nomenia obsoleta.  We are now in the difficult position that we cannot distinguish between two moths in different genera.  A further complication is that a third species, N. duodecimlieata is also a possibility,

According to MPG, male Venusia pearsalli have filiform (simple) antennae.  Unfortunately it does not say what the female antennae are like, nor do we know the sex of Jochen’s specimen, and we don’t see quite enough of the antennae to be sure what form they are.  MPG says the antennae (it doesn’t specify which sex) of Nomenia obsoleta are “apparently” unipectinate.

   And here is another selection of miscellaneous invertebrate from Ian Cooper:

*Ambigolimax valentianus (Pul.: Limacidae) Ian Cooper

   Thanks to Robert Forsyth for identification of the above slug, which I had originally mislabelled.

Unfortunately, we have not (yet) been able to identify the fly below.  If any viewer can help, please do so.

   Jeremy Tatum sends a photograph of this woodling moth that flew into his living room in Saanich last night.   Moths of the genus Egira are known as “woodling”moths.  They are largely western moths, and they are among the first noctuid moths to be seen in Spring.  Egira hiemalis is the earliest, usually appearing in February.  E. curialis (below) and others follow later.
