Southern Marsh Orchids

This year I've started to look at Caddisflies for the first time, using the excellent RES Handbook (Barnard & Ross 2012). So far I've only looked at those caught in my garden moth trap, which until yesterday comprised just the odd individual. Last night was better though, with 4 species trapped, these being: Limnephilus auricula, Rhyacionia dorsalis, Agapetus ochripes and this Hygropsyche pellucidula. The first of these breeds in pools and ditches, but the other three all occur in streams and rivers and may well have originated in the River Taff, which at its closest point flows just 400m from my garden.
Hygropsyche pellucidula (male)
My garden list now stands at a whopping 6 species. Many of the caddis need microscopic examination of their naughty bits to confirm identification, but the nice thing is that the genitalia are largely external and so can be viewed directly without having to resort to nasty skin-dissolving chemicals to make the features visible (as is the case with micro-moths).
