    Also, in the Island View/ McHugh/McIntyre Road corridor I counted 35 Cabbage Whites.

    Just a day after Jochen Möhr photographed  Thera juniperata in Metchosin (see yesterday’s Invert Alert), one turned up in Saanich.  That’s interesting, because all the books I have consulted (writes Jeremy Tatum) give Juniper as the only larval foodplant.  Juniper is not a very common wild plant here, so presumably the moth uses cultivated garden junipers.

  Hallowe’en is approaching, so maybe it’s appropriate that Ian Cooper is photographing spiders along the Galloping Goose trail:

   A brief butterfly note from Ron Flower:  Today October 13 we went back to the McIntyre reservoir where we saw two,  maybe three sulphurs and many Cabbage Whites  – mostly on the east side of the pond.

    Cheryl Hoyle sends photographs of a tiny fly and a micro moth from View Royal.  We are not at all certain what the fly is, but a possible guess might be Bradysia from the Famliy Sciaridae.  Flies of this Family are known as dark-winged fungus gnats – although not all have dark wings.  We thank Libby Avis for identification of the micro moth.

The Cabbage White caterpillar shown on October 10 has now pupated:

  Foodplants of the Banded Woolly Bear (Isabella Tiger Moth). 

   This caterpillar overwinters as a fully-grown caterpillar.   It is seen most obviouslyin October, and again in March.  Because it overwinters as a caterpillar, it is a difficult caterpillar to rear, and I have usually reared them from caterpillars found in March, when they have stopped feeding and are ready to pupate.  Consequently I have not had a clear idea of their foodplants.  Handfield lists a large number of  plants, mostly low-growing herbaceous plants  but also including some surprising ones such as Betula and Syringa.   I offered the caterpillar shown on October 9 some leaves, not being sure whether it was still interested in eating, or was looking for somewhere to hibernate.  I found that it eagerly and hungrily accepted Plantago major (included in Handfield’s list) and Rumex obtusifolium (not on his list)

Crane Flies (Tipulidae) and Winter Gnats (Trichoceridae)

  The Tipulidae is a very large Family.  It includes the large flies such as the familiar Tipula paludosa and similar large insects known here as crane flies and in Britain as daddy-long-legs.  But it also includes many much smaller flies, which superficially bear a strong resemblance to the Winter Gnats (Trichoceridae), and the problem is to tell the difference between the winter gnats and the small crane flies.  Unfortunately winter gnats can be found all year, not just in winter, so that’s no help. There is a difference in the wing venation – but that’s hard to photograph.  Another important difference is that the winter gnats have three tiny ocelli on the top of their heads.  The crane flies have no such ocelli.

  Below are two photographs (dorsal and lateral views) by Ian Cooper of a fly that we believe belongs to one or the other of these two Families.  You can see by the awkward way in which the animal holds its head that getting a clear photograph of the top of the head is going to prove quite a challenge.
