A Rout of slugs Arion ater rufus on the 11th August 2017 during all day rainfall, on the footpath at the back of Sunnymede, Chigwell Row,

Slugs, woodlice and centipedes. 20th March 2017 in the plantation. Thanks to Simon Taylor, Recorder for Molluscs, Essex Field Club for the identification and who states "Although the yellow slugs are indeed very yellow, the size of the tubercles (the texture of the skin) suggests to me that they are Limacus maculatus."
This Leopard slug Limax maximus was found under a log on Dog Kennel Hill woodland. Not normally active during the day it moved to avoid the bright sunshine.  Photos Brian Ecott  13th March 2017
Large black slug Arion (Arion) ater. On the cut grassland on Hog Hill. Not such a pest as other slugs as it prefers dead foliage, and is useful in clearing up grass cuttings on the field. 28th May 2016. Photo Brian Ecott.

With thanks to Simon Taylor, (Recorder of Molluscs in Essex for The Essex Field Club)  for his help with the identification of the slugs.

Simon Taylor further reports, "Since the publication of the FSC Aidgap guide and the work that led up to it, the position with the British Arionids has become rather more complicated. The slugs you photographed (above) are certainly Arionids but beyond that it is impossible to say just from a photograph. Even with the specimens in hand it is far from easy these days!"

Simon Taylor reports "that it is always tricky identifying from photographs but I am quite sure this is Monacha cantiana, the Kentish Snail (though very common in Essex)."  Simon Taylor is the Essex Field Club Recorder for Molluscs. Thanks to him for the identification  Photo Raymond Small and Brian Ecott on bramble leaf,  25 September 2016

This is a Song thrushes anvil. The thrush brings the snails and smashes the shells on an old green bottle releasing a tasty morsel. This thrush has been collecting Brown-lipped Banded snails. Cepaea nemoralis. The two shells centre and top centre are showing the brown lip. 30th January 2017.
