Rilaena triangularis (Herbst, 1799)
One of the very few Harvestmen found as adults during the Spring. Rilaena triangularis (formerly Platybunus triangularis) is a common species of woodlands and other well vegetated sites, but it has proved to be common at a range of sites and we have recorded it from urban gardens around Nottingham. Widespread throughout Nottinghamshire, though with few records from sites east of the Trent Valley.
