Harvestmen

Adam, a x20 hand lens is very useful when looking at this group I find, with tridents, tubercles etc being very evident at this mag. You can hold the harvestman (or harvestlady!) by its legs and examine most of the critical features. I'm not sure if triangularis is mature at this time of year so it may be worth checking that one and I've not seen Lacinius yet so can't comment on that one. We saw lots of Phalangium opilio at Nicholaston on the weekend and Leiobunum rotundum on Ivy blossom at Rhossili Church at night.
