Canal du Midi Part 1

A good deal of time has elapsed since the last post, the reason being that I have spent a long time trying to verify the butterfly sightings on my latest trip abroad, a cycle tour along the canal du midi from Carcassonne to Beziers. I've actually been back just over a week.

Overall, the most surprising thing about the trip was the extent to which butterflies dominated the nature sightings. Apart from the hirondelles, there were remarkably few birds around and other cyclists said the same.  There were scarcely any ducks until nearing the Mediterranean and the only land animals I saw were a couple of goats playing on a woodpile in a timber yard.  I wondered whether the hot, dry weather was at least partly responsible.

The first day was a circle to the Lac de la Cavayere.  All the streams leading into the lake had totally dried out and I gradually worked out that the best place to look was the point where the streams flowed (or didn't flow) into the lake as there was here at least enough moisture to sustain some flowers.

This is where identification problems begun and it's possible I have made the odd error. I was quickly able to identify wood grayling*, clouded yellow, silver-washed fritillary, wood white, white admiral, bath white, spotted fritillary and brown argus. However I encountered some very bright blues that were larger than common blues (also present) and didn't open their wings on settling.  My thinking is that they may have been adonis blues although they lacked the white markings on the underside of the bottom wing.  One I photographed I suspected was more likely to be a chalkhill blue.

Apart from a heron, I did get a quick sighting of a firecrest at the far side of the lake.

Bath White	Black Tailed Skimmer	Adonis Blue?
Chalkhill Blue?	Brown Argus	Clouded yellow**
Meadow Brown***	Wood Grayling*	Silver-washed Fritillary
White Admiral

Spotted fritillary

Wood White

Notes:

* Apparently it is however impossible to distinguish wood grayling from rock grayling without detailed examination

**  The pale form opens up the possibility of Berger's Clouded Yellow or Paled Clouded Yellow, both of which are present at this time of year.

*** Not quite the same as our own version - probably the hispula form

The second day was a trip to Homps along the Canal du Midi and started in light rain - hopefully a bit of relief for the forest fire that could be seen burning in the hills behind Carcassonne.  On the way out of the town there was a chap setting up to fish for carp with some large boilies and heavy tackle, unsurprisingly suggesting that there are large carp in the canal.  But I never at any stage saw them feeding or topping.

Apart from a few finches in a tree on the other side and butterflies already noted yesterday, the only sign of wildlife today was the large number of snails that were clinging to plant stalks along the bankside.
