Poplar Hawkmoth
A reasonable selection from the night before last. Not as many as I'd expected, but it could be that the recent cold spell has slowed things down in Moth Land, just as it has prolonged the sloe blossom and the bluebells.
Talking of Botany, I did a violet survey along the lane yesterday and counted hundreds of them. They are important because they represent the larval foodplant of one of our loveliest families of butterfly- the Fritillary. I am involved with a project later this Spring aimed at improving habitat (and therefore survival) of one of the most threatened of the Fritillaries, the Small Pearl Bordered. Yesterday's survey was not specifically SPB related, but was to enable me to contact the council and find out when they've got verge cutting scheduled, because if it's before June/ July that will be a disaster for the Silver Washed Fritillary who lives here.
Silver Washed are flutters of ancient woodland and I was thrilled when one visited our garden last summer to nectar on the world's most expensive buddleia (you may remember it's arrival two summer's ago costing a fortune and measuring the size of a five pence piece. It's earnt it's place in the garden now I feel).
Silver Washed lay their eggs in July and August on the north side of tree trunks about one metre up from the ground among mosses and lichens. When the larvae hatch out a fortnight later, they immediately hibernate in the crevices of bark where they remain until Spring. In May when the violets are out, they wake up and descend to the ground to feed on the new violet growth. They are fully grown by early June, when they pupate, attaching themselves to a leaf which they so closely resemble that they are very hard to find in this state. They remain as pupae until July when they emerge as adults, who spend a lot of time at the tops of trees but do descend to nectar (often on bramble).
This is why I am so keen to make certain the council doesn't cut the verges before any larvae have had a chance to grow properly and get back up on to the trees out of the way. I hope they will listen. Britain's verges represent an increasingly important resource in terms of wild flowers, nectar and larval foodplants for our insects. The more development that happens and the more agriculture intensifies, the more important these verge-side residues of what once was widespread become. I hope the council will understand the significance of this and take their guardianship responsibilities seriously. If you fancy a walk down your local road noting the presence of violets you could drop your local council a line and repeat what I've said in this post. The more people that raise awareness of this the better.
I'll leave you with a rather lovely egg shell the dogs and I found while out walking this morning. It's a Song Thrush. They are the most amazing blue. The second pic is a couple of Blackbird's from last spring for comparison,
