Please send your sightings by email to Jeremy Tatum (jtatum@uvic.ca). 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.

   Jochen Möhr writes from Metchosin:  The crowds are tapering off.  Yesterday (November 27), no Drepanulatrix and two  Erannis. Today just one Erannis – and even that one looks ready to take off.

Operophtera brumata (Lep.: Geometridae)  Jochen Möhr

 

   Jeremy Tatum writes:  This morning I visited the Nature House at Goldstream Park in hopes of finding Operophtera occidentalis or  danbyi, but I was out of luck.  There were several Erannis and Operophtera there, but as far as I could see all the Operophtera were brumata, and you know what I think the Erannis were.

   Jochen’s moths from Metchosin this morning.  Probably the same individuals as yesterday.

No pics taken.

 

3 Erannis sp.

3 Drepanulatrix sp.

 

   Jeremy Tatum writes:   Yesterday I compared photographs of adults our local Erannis species, known as E. vancouverensis, with a photograph from England of E. defoliaria.  Today I compare a photograph of the caterpillar of each.  I see no difference between the two species, in adult or larval form.

   Jochen Möhr  writes from Metchosin:  My son gave me a USB Microscope camera for my recent birthday.  I am slowly learning to use it. Today, I tried to do some spore prints of mushrooms.  When I took the mushroom off the sheet of paper, there were a few extremely tiny critters wriggling on the paper.  I took a few pics with the microscope device.  I think it is a springtail.

 

   Libby Avis and Jeremy Tatum agree that it is indeed a springtail.  The photograph is particularly interesting in that it is an underside, and we can actually see the spring. Springtails are included in several Orders within what is now regarded as the Subclass Collembola.

Jochen Möhr’s moths from Metchosin this morning.

 

1 Drepanulatrix sp.

4 Erannis vancouverensis

 

   Jochen sends pictures of his four Erannis. Jeremy Tatum writes:  Long-time viewers of this site will know that I have long been of the opinion that the so-called “Erannis vancouverensis” is in fact the European Erannis defoliaria.  I have taken the liberty of taking a photograph of an Erannis defoliaria from a British site, and I show it here with Jochen’s local photographs.  See if you can “spot the difference”.  I certainly can’t.  The caterpillars, too, are, to my eyes, inseparable.
