Deletions to the Essex Red data List
| MajorGroup | Family | Species | Entry deleted | Reason |
|---|---|---|---|---|
| Spiders | Gnaphosidae | Trachyzelotes pedestris | 28/05/2020 | The species has proved to be more widespread nationally than formerly, and is currently too widespread and easily found in the south of the county to remain in the Essex Red Data List. |
| Spiders | Araneidae | Zilla diodia | 15/11/2018 | Has become more widespread in the county and nationally |
| Spiders | Dictynidae | Nigma walckenaeri | 26/10/2018 | In recent years has spread widely in England. |
| Spiders | Araneidae | Larinioides sclopetarius | 20/11/2017 | More widespread than originally thought, and not apparently threatened. |
| Spiders | Thomisidae | Diaea dorsata | 17/11/2017 | More widespread than formerly and not threatened. |
| Spiders | Araneidae | Mangora acalypha | 04/07/2016 | In 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 & ants | Halictinae | Lasioglossum pauxillum | 22/07/2013 | This mining bee has increased in range and frequency in Britain and Essex markedly in recent years, |
| Spiders | Theridiidae | Steatoda grossa | 23/05/2013 | Increased in south-eastern England and Essex in recent years and usually found indoors or other situations associated with man. |
| Spiders | Araneidae | Argiope bruennichi | 17/04/2011 | Widespread in the county and to be downgraded soon from Nationally Scarce |
| Amphibians and reptiles | Anguidae | Anguis fragilis | 09/12/2009 | |
| Amphibians and reptiles | Colubridae | Natrix natrix | 09/12/2009 | |
| Amphibians and reptiles | Lacertidae | Lacerta vivipara | 09/12/2009 | |
| Grasshoppers & allied orders | Conocephalidae | Conocephalus discolor | 30/06/2009 | Conocephalus 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 & ants | Vespidae | Dolichovespula media | 26/06/2009 | At 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. |
| Spiders | Philodromidae | Philodromus praedatus | 11/02/2009 | Widespread in the county and to be downgraded soon from Nationally Scarce |
| Spiders | Philodromidae | Philodromus albidus | 11/02/2009 | Widespread in the county and to be downgraded soon from Nationally Scarce |
