    Here’s a spider from the Galloping Goose Trail, photographed by Ian Cooper on March 6.  This is what Dr Bennett writes:

 

I looked at these with Darren Copley. We agree that the spider is a linyphiid but are unsure whether linyphiine or erigonine. Possibly a Bathyphantes (linyphiine) but could also be something else such as a Grammonota (erigonine). There aren’t actually all that many linyphiids with chevron-like abdominal patterns. I think we lean towards Bathyphantes.

 

    We hope these long words are long enough for our viewers – and we thank Robb and Darren for taking so much trouble to identify a modest little spider.  For those who may be slightly baffled by the long words, they are not as mysterious as they sound.  Sheetweb spiders belong to the Family Linyphiidae (Families end in –idae), and members of this Family are referred to as linyphiids.   The Family Linyphiidae includes several Subfamilies (ending in –inae), such as Linyphiinae and Erigoninae, and spiders belonging to these linyphiid subfamilies are referred to as linyphiines and erigonines.  Bathyphantes and Grammonata are genera (plural of genus.)  So now you know!

   And talking of tiny insects, writes Jeremy Tatum, here’s one from the Tineidae – which doesn’t mean tiny.  It is a web-spinning clothes moth, regrettably from my apartment.

  And now – a big insect:   Ian Cooper found this cocoon of a giant sawfly along the Galloping Goose Trail.  Not sure which of two species it is.

   Ian also found there this chrysalis of a Tiger Swallowtail butterfly.  We can’t tell for sure whether it is a Western or Pale Tiger.

   We have lots of similar species of tiny spiders in our area, and, like tortricid caterpillars and lots of other groups, we can’t always manage to identify them, so we’ll have to settle for this one, photographed along the Galloping Goose Trail on March 1 by Ian Cooper, as either a linyphiine linyphiid or perhaps a pimoid.

  Spring hasn’t quite arrived yet, but Rosemary Jorna photographed two syrphids in her Kemp Lake garden  on March 3.  The first is a Narcissus Bulb Fly.  Thanks to Dr Jeff Skevington for identifying the second as probably Melangyna lasiophthalma , decribed by Jeff as a very early Spring species.
