   Here’s the easy-to-identify colour variety of Coryphista meadii:

   Jeremy Tatum shows an Orgyia antiqua from Salmonberry at Blinkhorn Lake this afternoon.  It has a rather unkempt appearance because it has just undergone ecdysis (in English, it has just changed skin), and it hasn’t tidied its new clothes yet.  It will look much smarter later on.  (Libby will probably guess why I was looking on Salmonberry at Blinkhorn Lake.  I didn’t find what I was looking for.)

    Mike Yip writes from Nanoose:   Common Wood Nymphs have been flying in my yard since Sunday. They were constantly on the move and impossible to photograph until I discovered their weakness – blackberry wine. I simply set up close to my small blackberry patch and waited.  Within 15 minutes  I had some very decent photographs.  [I’d say very decent indeed!   Jeremy Tatum]

   Gordon Hart photographed the moth below at his Highlands home on August 4.  Since we could see only the underside of the wings, I despaired (writes Jeremy Tatum) as to whether we could identify it.  For Libby Avis, however, nae bother!  Libby writes:  “That one’s easy – for once!

Ceratodalia gueneata. We’ve had five this week in Port Alberni.  One of the few moths that always sit with their wings up. I would probably find it hard to identify it from the top side.”

   Gordon Hart’s moths from Highlands, August 6:

 

The first is one of those pugs that are awfully difficult to identify.  Jeremy Tatum writes:  I’ll label it possibly Eupithecia annulata – though it could well be something else!

Eulithis xylina (Lep.: Geometridae)

plus one of those little crambids that we despair of identifying.

   Jochen Möhr reports from Metchosin:

1 Perizoma curvilinea 

 

Yesterday afternoon:

2 Ochlodes sylvanoides

1 Vanessa cardui

And this afternoon, a fine caterpillar:

   And here’s a nice miscellany from Gordon Hart in the Highlands.  The centre-stage insect is an antlion.  Don’t know the exact species.  Don’t think we can identify the noctuid moth, which is just a little out of the depth of focus.  The small insect nearest the right hand edge of the photograph is, I think, a culicid, better known to most of us as a mosquito.  Never thought we’d find out what the other small flies are, but Libby Avis identified them!   They are dark-winged fungus gnats (Dip.: Sciaridae).   We can even make out the wing venation on one of them.

Crab spiders seem to be able to capture and subdue some quite large prey.  Yesterday Rosemary Jorna saw two of them, each with a large bumble bee, in her garden in the Kemp Lake area.

Random thoughts (Jeremy Tatum):

 

How do you spell fishfly, bumble bee, etc.?

 

I think the rule that I’ll follow on Invert Alert is this.  If it is a fly, then “fly” is a separate word.  If it is not a fly, “fly” is attached.

 

Thus    House Fly                   Butterfly

Drone Fly                   Dragonfly

Horse Fly                    Stonefly

Hover Fly                    Fishfly

Dung Fly                     Caddisfly

etc., usw.    By this rule, I suppose it should be Bumble Bee

 

Talking of stoneflies, we’ve had only three photographs of them in the ten years of Invert Alert.  There are usually lots at Goldstream  Park.   Photographers please note.

 

In the days of Moses Harris (1730-88), the word “fly” was used for any insect, in much the same way as today some people misuse the word “bug” to mean any insect.  Thus Moses Harris wrote that “The Camberwell Beauty is one of the scarcest Flies in England.”
