Other invertebrates

Slender Slug, Angling Spring WoodSix species of Woodlice (isopods) have been recorded, most of them very common.  The uncommon Porcellionides pruinosus, however, has been regularly recorded at Longdown Bank.  The hoppers (amphipods) are generally restricted to our sea-shores, but one Landhopper Arcitalitrus dorrieni has been imported from time to time with tree-ferns from New Zealand and become established in damp woodlands especially in Cornwall and elsewhere near the coast.  Specimens of this creature were found in 2008 in damp leaf litter in Angling Spring Wood, much further inland than most other records.

42 mites have been recorded, mostly through their propensity for causing conspicuous galls on plants, like the familiar red swellings on maple and sycamore leaves.  The irritating harvest-bug was recorded from Perks Lane Picnic Site in 1987.  Many more mites remain to be recorded.  Also under-recorded so far are the spiders (23), harvestmen (4) and pseudoscorpions (3).  Similarly the aquatic crustaceans, millipedes and centipedes need much more study.  A preliminary study of earthworms has resulted in seven different species being recorded, but this, too, leaves much more work to do. The remarkably thin Horsehair Worm thrives in at least one Perks Lane garden.

Recording of rotifers in the area has been carried out by Eric Hollowday, who has so far identified 37 different species.

Molluscs (slugs and snails) have also been extensively studied, with 82 species recorded.  These include several ancient woodland indicator species of national concern, including the beautiful (for a slug) Slender Slug at Angling Spring Wood and five other woodlands in the area, Ash-black Slug also at Angling Spring Wood, and the fascinating Tree Slug that emerges after heavy rains, sometimes in large numbers, to graze lichens from smooth-barked trees such as hornbeam and beech.  Among the snails, the rather diminutive “Large Chrysalis Snail”, a rare Chilterns speciality, survives at Perks Lane Picnic Site, and the distinctive Round-mouthed Snail is often abundant in undisturbed grassland and woods on chalk.  Other ancient woodland indicators have not been seen for some while (but may still be around), including the Point Snail (last seen 1916), Three-toothed Moss Snail (1920), and Mountain Bulin (1951).  Wetlands harbour other snails of interest, such as Lake Limpet (Peterley Manor Farm Pond), Nautilus Ram’s-horn (Deep Mill), and Button Ram’s-horn (upper Misbourne stream where it often dries up).
