   Jeff Gaskin writes:  I’ve been seeing a fair number of Painted Ladies lately.  Especially today, in fact in Beacon Hill Park I saw five, and in the Cecilia Ravine Park there were two.

   Some more moths from Metchosin, sent by Jochen Moehr:

More photographs and observations tomorrow!

Sorry – no posting yesterday (September 19).

Today we have two syrphid flies, and we are grateful to Jeff Skevington and Andrew Young for their identification.  The first one, perched on an anemone, was photographed by Jochen Moehr in Metchosin.

   The second one was photographed on Pender Island in July by Ren Ferguson

The spider below was photographed yesterday by Rosemary Jorna in the Kemp Lake area of Otter Point.  We are grateful to Robb Bennett for identifying it for us as a fenmale Araneus saevus  or Araneus nordmanni.  Its head is hidden by its massive abdomen.

   Jochen Moehr sends a photograph of a beetle from his property in Metchosin.  Thanks for Charlene Wood, who writes:  Most beetles have 11 antennal segments, but more important to family ID are the tarsal segments on all three sets of legs. Luckily, this photo gives another clue that is helpful in this case – the maxillary palp is triangular in shape, which ruled out the similar shaped Ground Beetles and leads me to the family Tenebrionidae (Darkling Beetles). Tentatively, it looks to be in the genus Helops. Five species range into SW Canada. 

Probably Helops sp. (Col.: Tenebrionidae) Jochen Moehr

   Jochen also sends photographs of more moths and a caddisfly from Metchosin.  Thanks for Libby Avis for doing the identifications.  Some of the moths in the Agrochola/Sunira group can be a challenge to identify.  Jochen’s moth is either Sunira decipiens or S. bicolorago, and, from the ranges of these two species, it is most likely decipiens.

Of the next one, Libby writes:  This one is in what PNWM refers to as the “Xestia finatimis species group”. Four very similar species, three of them (finatimis, infimatis & verniloides) very hard to distinguish even when they aren’t faded. This one looks to me like possibly finatimis or verniloides,  but I wouldn’t care to make a bet on it!

   Next:  Tetracis probably pallulata (jubararia is the other option for the fall). Used to be that pallulata was considered to be the one with darker median lines, closer together which this one has. However,  but I read a paper on them a while ago which seemed to cast doubt on the whole thing – nothing ever seems to be simple anymore!

   Of the caddisfly, Libby writes:  We get a lot of caddises at the moth light and I got a bunch of them ID’d by BOLD a few years ago. This one looks like a pretty good match for one of ours which was confirmed as Lenarchus rho photo attached) but there are also other Lenarchus species which are similar and I’m not that confident on how far you can go on these visually.

   Mike McGrenere sends a second photograph of the American Lady that he found at McIntyre reservoir on September 10.  This photograph allows a clearer view of the underside.  This is a rarity here, and indeed in British Columbia, although it is the second report we have heard of on Vancouver Island this year.  One was photographed by Martin Dollenkamp from Black Creek on August 8. (See the posting for August 11.)  On 2015 August 26 one was photographed at Ucluelet by a visitor from the UK, Patrick Moore, and was shown on the Sussex (England) butterfly website

   There are still a few Painted Ladies around – Anne-Marie Hart spotted a fresh one nectaring on a Buddleia bush in their Highlands garden yesterday.

Libby Avis tells us that she is still seeing lots of Nepytia phantasmaria (see yesterday’s posting) in Port Alberni –  15 of them last night!

Janet Renouf sends a photograph of a green caterpillar from under an oak tree.  It is a Rough Prominent Nadata gibbosa, and it looks as if it is just about to pupate at any moment.  Unfortunately it seems to have had some sort of a mishap, because it usually spins a tough cocoon in which to pupate, and, without its cocoon, I don’t rate its chances of survival greatly.

   Gordon Hart sends photographs of damselflies from the Beaver Lake retriever ponds, September 15.  We are grateful to Rob Cannings for the identifications.  Rob writes: The first is a Lestes male. Unfortunately, the tip of the abdomen is out of focus, which makes identification tricky from the dorsal view. The two species common here in September are L. disjunctus and L. congener and, based on this and certain characters, it’s one of those. I’m afraid I can’t really tell.   The second is a female Enallagma carunculatum. Eighth abdominal segment is all black on top.

Jeremy Tatum writes:  Here is an objet trouvé from Swan Lake.  It is the empty skin of a chrysalis of a Lorquin’s Admiral hanging from an apple tree.  The butterfly probably emerged from the chrysalis several months ago.

   The Cabbage White chrysalis below, however, is occupied!   The butterfly might emerge later this year, but more likely next spring.

Jochen Moehr sends some moth photographs from his home in Metchosin.  We are very grateful to Libby Avis for identifying them for us.

The next one is a pug, and they are always difficult.  Libby expresses some caution for her identification as probably E. graefii, though I think she has it just right.  Looks like a very good fit to me (Jeremy Tatum)

Libby writes that she has been seeing more than usual Nepytia phantasmaria in Port Alberni. She writes:  Over a two week period at the beginning of September we were getting 10 or 12 a night – actually counted 28 on Septeber 6!  I have attached a photo of three of them from September 4.

Rarity Alert!!!

Mike McGrenere writes:     I had an Orange Sulphur last Sunday (September 10) at McIntyre reservoir along with an American Lady. There were about 40 Cabbage Whites as well. Yesterday (September 15) at the reservoir, there were only about 5 Cabbage Whites. I have attached photos of the butterflies.

   Jeremy Tatum reports a Red Admiral perched on the Mahonia just outside the entrance to the Mount Tolmie reservoir, 5:45 pm today.

Annie Pang is bravely taking on the task of rearing a caterpillar of a Spotted Tiger Moth – feeding, unusually, on birch.
