Arolwg o ffawna infertebrat Chwarel Marford yn 2018, gan ganolbwyntio'n benodol ar golynogion (gwenyn, gwenyn meirch a morgrug). 2019-10-01 NRW_DS122469 Following management work in Marford Quarry to increase the amount of bare sand habitat for psammophilic insects, a survey in 2018 recorded 118 species of aculeate bees, wasps and ants including 35 species new to the site. The cumulative aculeate list now stands at 171 species, with 81 bees, 80 wasps and 10 ants, 80 wasps, making Marford Quarry one of the most important site in Wales for this taxonomic group. The survey also recorded four new psammophilic aculeates - Anoplius infuscatus, Arachnospila wesmaeli, Coelioxys conoidea and Coelioxys inermis - and the psammophilic ground beetle Harpalus tardus at its only Welsh inland locality. The overall total for the quarry now stands at 31 psammophilic species including 26 aculeates, two beetles and three flies. Six new dead-wood nesting aculeates were found – Ancistrocerus gazella, Ancistrocerus scoticus, Megachile ligniseca, Psenulus pallipes, Stigmus solskyi and the Hornet Vespa crabro – resulting in a cumulative total of 43 species (42 aculeates and one beetle). Both the psammophilic faunal assemblage and the dead-wood assemblage are considered to be currently in favourable condition although there is an urgent need to provide more deadwood habitat which is at a premium. It is also important to maintain early-successional sandy habitats by a programme of regular excavation work. The finding of the solitary wasp Gorytes laticinctus in Marford Quarry is arguably the most significant record in the 2018 survey given its UK distribution and indicates a major range extension. Other important records were made of other insects including the tachinid flies Freraea gagatea (new to Wales), Gymnosoma rotundatum and Wagneria gagatea (both at 2nd Welsh localities) and Leucostoma simplex (new to north Wales), the Alder Leaf Beetle Agelastica alni (otherwise known from Fagl Lane Quarry), and the parasitic wasps Sphecophaga vesparum and Haltichella rufipes (both new to Wales).
