Deletions to the Essex Red data List

MajorGroupFamilySpeciesEntry deletedReason
SpidersAraneidaeMangora acalypha04/07/2016In Essex this species has been incresasing its distribution and frequency in the past few years and is now common in many parts of the county where it was previously absent. Previously it was mainly restricted to a small central area in the county between Danbury and Tiptree Heath, where it occurs in relic heathland habitats. It had never been recorded in the Epping Forest area, despite many searches in suitable locations.
Bees, wasps & antsHalictinaeLasioglossum pauxillum22/07/2013This mining bee has increased in range and frequency in Britain and Essex markedly in recent years,
SpidersTheridiidaeSteatoda grossa23/05/2013Increased in south-eastern England and Essex in recent years and usually found indoors or other situations associated with man.
SpidersAraneidaeArgiope bruennichi17/04/2011Widespread in the county and to be downgraded soon from Nationally Scarce
Amphibians and reptilesAnguidaeAnguis fragilis09/12/2009 
Amphibians and reptilesColubridaeNatrix natrix09/12/2009 
Amphibians and reptilesLacertidaeLacerta vivipara09/12/2009 
Grasshoppers & allied ordersConocephalidaeConocephalus discolor30/06/2009Conocephalus discolor has been removed from the ERD List due to its continued range expansion in the county. It is now a widespread and common bush-cricket in no current need of special conservation measures.
Bees, wasps & antsVespidaeDolichovespula media26/06/2009At the time the Essex Red Data List was first put together, this wasp was still rare in the county with only a few records. Although still officially Nationally Scarce (Notable A) it is now removed it from the Essex Red Data List to reflect its present distribution and status in the county.
SpidersPhilodromidaePhilodromus praedatus11/02/2009Widespread in the county and to be downgraded soon from Nationally Scarce
SpidersPhilodromidaePhilodromus albidus11/02/2009Widespread in the county and to be downgraded soon from Nationally Scarce
