This blog provides an informal forum for terrestrial invertebrate watchers to post recent sightings of interesting observations in the southern Vancouver Island region. Please send your sightings by email to Jeremy Tatum (tatumjb352@gmail.com). Be sure to include your name, phone number, the species name (common or scientific) of the invertebrate you saw, location, date, and number of individuals. If you have a photograph you are willing to share, please send it along. Click on the title above for an index of past sightings.The index is updated most days.

    About seven people attended the monthly Butterfly Walk yesterday.  We went out to Island View Beach.  We saw several Woodland Skippers and Large Heaths (“Ringlets”) nectaring on Douglas Asters in the grassy fields inland from the beach, and a female Purplish Copper on the sand dunes apparently ovipositing on the Beach Knotweed Polygonum paronychia.  And, of course, a few inevitable Cabbage Whites.  Finally, a Red Admiral awaited us on our return to Mount Tolmie, for a total of five species – not bad for September.   There were lots of tiny micro moths on the sand dunes, one of which was photographed by Aziza Cooper. Not sure what they are – other than a species of crambid moth.  Some of the more undisciplined members of the party, (that is to say, all of us) saw a few birds – Common Nighthawk, Wilson’s Snipe, Cedar Waxwing, Merlin, Mourning Dove, and lots of American Pipits.  Jeremy Tatum

 

   Here are a few of Aziza’s photographs from the trip.

  Meanwhile Annie Pang photographed a potter wasp (to quote Vera Lynn – “don’t know where, don’t know when”!), identified by Matthias Buck.

    Jeremy Tatum writes:  I have been asked what were the 26 species of butterfly that I saw in a small area of Sussex, England, in two days in August!  Well, that doesn’t strictly belong in this Vancouver Island site, but, to satisfy the curious, here they are:

 

Small Skipper                           Small Copper                           Peacock

Essex Skipper                           Small Blue                                Comma

Silver-spotted Skipper            Brown Argus                            Dark Green Fritillary

Large Skipper                           Common Blue                          Speckled Wood

Clouded Yellow                        Chalkhill Blue                           Wall Brown

Brimstone                                 Holly Blue                                Gatekeeper

Large White                              Red Admiral                             Meadow Brown

Small White                              Painted Lady                            Small Heath

   Monthly butterfly walk, Sunday September 4.   All welcome.   Meet at the top of  Mount Tolmie, 1:00 p.m.

 

    Rosemary Jorna writes that the moth below was resting on the duff in her Kemp Lake garden yesterday morning.  It is a Large Yellow Underwing moth, a European species by now well established here.  The shape is quite characteristic.  Although the pattern and colour on the wings is very variable, and this is an extreme pale version, one can usually recognize the species by the double black spot near the apex – a feature that is very obvious in this example.

   Annie Pang sends a photograph of a hover fly (Syrphidae).  Many hover flies (also known as flower flies) are boldly and, one would think distinctively, marked, and one would think they would be easy to identify.  Unfortunately most specialists agree that they are not as easy to identify from photographs as one would think, and it is probably best to leave this one, beautifully marked as it is, as just a syrphid.

   On the August 29 posting, we mentioned a sighting on August 24 by Aziza Cooper, at Turkey Head, of a sulphur butterfly.  Some may wonder – as I did at first – how good a sighting it was.  In fact Aziza had a good close look, supplied excellent field notes, and took a photograph.  The photograph is probably not an award-winner, and probably wouldn’t reproduce well on this site, but we can confidently assure viewers that it really was a sulphur, and consequently we should be looking out for them right now!  Good luck!

  Colias alert!  On August 24, Aziza Cooper saw a sulphur (exact species undetermined) on Gumweed at Turkey Head.

 

Jeff Gaskin reports a Western Tiger Swallowtail on Mount Tolmie, August 11, and, on August 12, also on Mount Tolmie, 1 Red Admiral, 1 West Coast Lady, and 1 Painted Lady.

 

Annie Pang found a spider weaving a web on the side-view mirror of her car on August 24.  Thanks to Robb Bennett for confirming its identification as Araneus diadematus

   Aziza Copper photographed the micro moth shown below near the Garcia reservoir on August 26.  Thanks to Libby Avis for identifying it as the Alfalfa Webworm Moth Loxostege cereralis.

 

Alfalfa Webworm Moth Loxostege cereralis (Lep.: Crambidae)  Aziza Cooper

   The name cereralis immediately raises a spelling question.  Surely this is a misspelling for cerealis ­ –  a spelling that is sometimes seen in the literature.   The definitive way to determine the correct spelling is supposed to be to go back to the original scientific description, and see what spelling the author used.  This is often easier said than done, and I didn’t manage to do it for this moth.  However, I found enough to convince myself that the cereralis spelling is the correct, or at least the preferred, spelling.  It is not named after what you eat for breakfast.  Rather, it is named for Ceres (genitive Cereris), the Goddess of Agriculture.

 

Thanks to Claudia Copley for identifying some recent photographs of grasshoppers and bush-crickets (katydids) that have been sent to Invertebrate Alert.  The first was photographed  recently by Paige Erickson-McGee.  Claudia writes that it is Melanoplus sp., and probably M. femurrubrum, the very common Red-legged Grasshopper.

Next is Meconema thalassinum, a bush-cricket, photographed by Cheryl Hoyle in Saanich on August 27.  Claudia remarks that this is non-native, and a very recent invader.

Claudia has also identified Cheryl Hoyle’s grasshopper posted on August 5. Scroll down to that date to see the photograph and the identification.
