'''''Myolepta potens''''' is a [[Europe]]an [[hoverfly]].

The species ranges from [[France]] and [[Germany]] through [[central Europe]] to the [[Black Sea]].
It is rare throughout its range and is listed in the [[IUCN Red List|Red Data Book]]s of a number of its [[range state]]s. It is listed by the [[Council of Europe]] as a [[Saproxylic]] (deadwood-dependent) [[Indicator species]], because its presence indicates that a large quantity of standing deadwood is also present.

The species was discovered in [[Great Britain|Britain]] in 1945 by [[John Cowley (entomologist)|John Cowley]] at [[Loxley Wood, Somerset|Loxley Wood]] and another [[woodland]] site near [[Shapwick, Somerset|Shapwick]] in [[Somerset]] and identified by J. E. Collin. Cowley found more specimens in the same area in 1946, 1947 and 1949. Subsequently, fellow [[dipterist]] [[E. C. M. d'Assis-Fonseca]] found a single male in [[Blaise Wood]] near [[Bristol]] in 1949, and in 1950 E. E. Lowe found the species at [[Combe Dingle]], which is close to the [[Blaise Castle Estate]] within which Blaise Wood lies. J. C. Hartley found six [[larva]]e in a [[rot-hole]] at [[Ashton Court]], Bristol in 1961, thus providing proof of the species' breeding in Britain. Despite attempts to relocate the species in its Bristol and Somerset sites in the 1980s and 1990s, it has not been refound (Loxley Wood is largely coniferised and therefore no longer suitable for supporting the species).

In the [[Institute for Terrestrial Ecology]]'s [[Atlases of the flora and fauna of Britain and Ireland|Provisional hoverfly atlas]] published in 2000, the species was listed as [[extinct]]. During an [[English Nature]]-commissioned survey of [[Moccas Park National Nature Reserve]] in [[Herefordshire]], [[Andy Godfrey]] found ''Myolepta potens'' larvae in a rot-hole. Subsequent survey work revealed that there is a strong population at this site using rot holes in several different species of tree.

Two [[English names for organisms|English names]] have been coined for this species, although neither has gained widespread usage: the '''Western wood-vase hoverfly''' <ref>{{cite web | url = http://www.woodland-trust.org.uk/ancient-tree-forum/atfnews/news03/hoverfly.htm | title = Ancient- tree hoverfly rediscovered in the UK after more than 50 years. | access-date = 25 Nov 2008 | date = 29 April 2002 | publisher = [[Woodland Trust]] |work=Ancient Tree Forum | url-status = dead | archiveurl = https://web.archive.org/web/20071207015006/http://www.woodland-trust.org.uk/ancient%2Dtree%2Dforum/atfnews/news03/hoverfly.htm | archivedate = 7 December 2007 }}</ref> and the '''Moccas hoverfly''' <ref>{{cite web | url = http://www.english-nature.org.uk/about/teams/team_photo/NatConns2.pdf | title = Reprieve for 'extinct' Hoverfly | access-date = 25 Nov 2008 | publisher = English Nature }}</ref>
