A beautiful day to be out and about. I travelled a few miles to Lesnes Abbey in south-east London to attend a field studies council teaching day on the identification of Spiders. Now, as regular readers know I do recording for Butterflies, Dragonflies and Bumblebees on my local patch but I have to confess that I know next to nothing about spiders. Unlike the others, they don’t tend to make themselves obvious, quite the opposite in effect so I thought this course, part of the FSC’s Biolinks project was an excellent opportunity to at least start to remedy that.

The morning was taken up by an introductory talk on common spiders and how to recognise them. Species-level identification can be very difficult in the field so it is often about just identifying the family they come from – in some case there are only one species in a family which helps. In the afternoon we spent the time in and around Lesnes Abbey. We started with a wall in the ruins and soon had examples of 5 or 6 species to look at – who would have guessed that so much lived in an old wall. The highlight was a large but very agile example of the Lace web Spiders (Amaurobius ferox) along with a Zebra Spider (Salticus scenicus)and the more common lace web spider (Amaurobious similis).

Next, we examined a bush and found another group of species. My favourite was the Cucumber Spider (Araniella cucurbitinia).

Our final stop was some grassland where we found some Large Jawed Spider (Pachygnatha spp) along with Wolf Spider. My favorite here was the Cricket-bat Spider (Mangora acalphya).

This was a very worthwhile and productive day. Thanks to Lawrence and Keiron who led it. I would encourage anyone who wants to improve their invertebrate identification to check out the Biolinks page at http://www.field-studies-council.org/individuals-and-families/fsc-biolinks-courses.aspx
