   Jody Wells sends a photograph of a female wolf spider carrying her egg sac at Saanichton Spit, April 23.  Thanks to Dr Robb  Bennett for identifying it as Pardosa lowriei.

   Mr E sends a photograph of a Yellow-bordered TaIldropper Slug from Saanich (rather a large area!) yesterday:

   And a non-biting midge, Family Chironomidae,  possibly genus Chironomus.  Although we cannot be absolutely certain of the genus, we can at least be certain of the sex.  The males have large feathery antennae;  this one is a female.

   And a young spiderling.  Dr Bennett writes:  A juvenile theridiid, a species of broad-sense “Theridion” which includes a number of genera more-or-less recently split off from Theridion.

   Jochen Möhr’s moths from Metchosin this morning:

2 Egira rubrica

1 Egira simplex/crucialis

1 Feralia comstocki

4 Hydriomena manzanita 

4 Melanolophia imitata

1 Orthosia revicta

1 Orthosia praeses

1 Orthosia transparens

4 Venusia obsoleta /pearsalli 

 

   Jeremy Tatum writes:  On April 21 and 22 we showed clear unambiguous examples from Jochen of Egira crucialis  and E. simplex.  It seemed that the problem was solved.  Now Jochen comes up with the moth below.  Libby Avis and I are in complete agreement – we don’t know which of the two it is!

  Thanks to Libby for spotting the ID of the next one – I was on the point of posting it as something else!  Jeremy Tatum.

   Jeremy Tatum writes:  Here is a caterpillar of a Winter Moth.  It came in on a leaf that was intended for someone else, but I thought I might as well photograph it before putting it out again on Mount Tolmie.  At this time of year it is difficult to find foodplants that do not already have one or more Winter Moth caterpillars per twig.

   Mr E sends photographs of some miscellaneous creatures from around Elk Lake.

 

Not identified at press time. Suggestions, anyone?  Believed to be an aphidid.   Mr E

   For the spider below, Mr E tentatively identified it correctly as Callobius sp., so we are glad to have Robb Bennett’s confirmation.  Dr Bennett writes:  One of our two local common woodland amaurobiids – Callobius severus.  Very slight possibility it’s Callobius pictus but I think severus is correct. They are one of several spider species that I commonly find in my firewood pile.  And their tangly matted webs are often a feature of old Douglas-fir bark.

     Mr E also suggested Epuraea for the beetle below, so we are delighted to have confirmation of this from Scott Gilmore.


Epuraea sp. (Col.: Nitidulidae)  Mr E

Not identified at press time. Believed to be a nymph of a bug. Suggestions, anyone?

 

Jochen Möhr’s moths from Metchosin this morning:

 

2 Egira simplex

1 Egira rubrica

1 Eupithecia sp.

1 Eupithecia graefii

1 Feralia comstocki

4 Hydriomena manzanita 

1 Melanolophia imitata

2 Orthosia transparens

2 Perizoma curvilinea

1 Phyllodesma americana

1 Tyria jacobaeae

5 Venusia obsoleta /pearsalli

 

Yesterday, writes Jeremy Tatum, we mentioned the difficulty that we often have in separating Egira crucialis from E. simplex, and we showed a picture of what I said was an ideal E. crucialis.  Today, Jochen provides us with two pictures of what I what describe as truly ideal Egira simplex.

   Val George writes:  Yesterday, April 20, I conducted my April butterfly count for Mount Douglas and the surrounding area.  The result was:  10 Cabbage Whites, 10 Western Spring Azures, 3 California Tortoiseshells, 2 Sara Orangetips, 2 Grey Hairstreaks. 

 

Jeremy Tatum writes:  I saw just one California Tortoiseshell on the Mount Tolmie reservoir at 6:00 pm yesterday.  But at UVic I saw a Pacific Sideband also known as Faithful Snail, which some might say is just as beautiful in its own modest way.

   Libby Avis writes:  I got a Ufeus satyricus at the light here in Port Alberni April 19th. First time we’ve seen one here. I don’t think there are many reports of it on the island. You posted one from Jeremy Gatten three years ago.  [See Invert Alert for 2017 March 13.]

   [Jeremy Tatum remarks:  Followers of this site will have noticed that we have a lot of difficulty separating E. simplex and E. crucialis.  This one, to me at any rate, is a rare case where I think we can be as sure as sure that this is indeed an ideal C. crucialis.]

   Jochen Möhr writes from Metchosin:

 

   We have very regular visits of Sara Orangetips from about 11 am to 5 pm.  Yesterday, I watched continuously from 3:45 to 4:45, and in that hour counted 18 Sara Orangetips which gives an average interval of a bit over three minutes between sightings.  In reality the interval between sightings was more like five to twenty minutes, but repeatedly, I saw two or three simultaneously.  Some females hovered at length among the grasses and I think they were ovipositing. [The eggs are laid on Arabis glabra and other related brassicaceous plants (not cabbage!).  Jeremy Tatum]  I saw about 1 Western Spring Azure for every three orangetips, and only one single Cabbage White and one Comma all day. 

 

   But walking through the meadow, I got close to one Western Spring Azure and one Moss’s Elfin.

   Jochen continues:  Today, I watched from my deck from 10:45 to 11:45 AM.  In that hour, I had 19 sightings of Orangetips,with up to three simultaneously appearing.  I also saw two Western Spring Azures  and one white, presumably a Cabbage White, which engaged in a dance with one of the orangetips, both rising high above the tree tops.

 

   Jochen’s moths from Metchosin this morning:

 

1 Anticlea vasiliata

1 Behrensia conchiformis

4 Cladara limitaria 

1 Eupithecia graefii

1 Feralia comstocki

5 Hydriomena manzanita

4 Melanolophia imitata

1 Perizoma curvilinea

1 Schreckensteinia festaliella

1 Unidentified pyralid

2 Xanthorhoe defensaria

 

  Jeremy Tatum writes:  Schreckensteinia festaliella is quite a mouthful for a tiny moth scarcely larger than a House Fly.  The Family name, Schreckensteiniidae, is probably not familiar to everyone.  The caterpillar feeds on Salmonberry and Raspberry, so, if you grow Raspberries, you might see one occasionally.  You might even have eaten one.
