Now that the trees are all in leaf, Willows in particular are dripping with the silken tent nests of Lackey Moth caterpillars. While Lackey Moths are common across Southern Britain and Central Europe, they've only recently managed to form a stronghold on Bardsey. In 2006 there were only three adult Lackey Moths, all recorded in July, and they had not been noted for seven years previous to that. The first silk tent was found in Nant Withy in 1995. Since their single figure, erratic, occurrences in the late 90's, it seems the small arrival in 2006 was enough to form a colony on Bardsey and several tents were recorded in 2007. I (Giselle) did a count of the silk tents in the Obs Garden yesterday. There are at least 40 nests (that I can see from my height of 5'2) and double figure counts are also present in the Withies and in several of the gardens on the island.
These silken tents are woven by the caterpillars and are used to regulate their temperature, acting as a sort of sleeping bag for them to nestle into on cold days. On warm days they can be seen on top of their tents, basking in the sunshine. (c) Giselle Eagle
