   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.

   Jochen Möhr’s moths from Metchosin this morning:

 

2 Drepanulatrix

2 Operophtera

1 Sunira decipiens – same individual as lately, now on the floor.

 

   As winter approaches, we are almost being reduced to photographing just winter moths and firebrats.

3 Drepanulatrix sp.  

1 Epirrita autumnata
