The Cerambycidae list of Tophill Low NR, East Yorkshire rarely sees additions, totalling just seven species up until July 12th 2017. However, that was before this Arhopalus rusticus was found during moth recording. On checking records, it appears to be the third VC61 record and 8th county record, per the recently published Yorkshire Naturalist Union Coleoptera list 2017.
Scarcer still was this Argyresthia bonnetella f. ossea taken at light on July 14th – the third documented record of this form in Yorkshire following communications with a leading expert.
July 2016 saw Kent Black Arches Meganola albula added to the Tophill Low list. Rarely recorded away from coastal haunts, further records weren’t expected, so it came as something of a surprise to trap a single on the 14th, followed by two others on the 15th in a different part of the reserve.
2016 was also the year Coronet Craniophora ligustri was added to the site list, the individual below attracted to light on the 14th the second site record.
This Batrachedra praeangusta trapped on 15th was a new species for Tophill Low and was one of 140+ species attracted to the lights that night – thought to be the highest single night haul in site history. The period 13th-15th yielded in the region of 180+ species, but the total is yet to finalised. An impressive number for a site which is still relatively ‘young‘ given planting of the main woodlands only commenced post-site construction in 1959.
The 656th species to be recorded on site was Catoptria pinella on the 19th, while the supporting cast in recent days included Ypsolopha scabrella and Pale Mottled Willow Caradrina clavipalpis.
Butterfly recording saw nearly 1000 individuals of 17 species recorded on the July 17th, while the dragonflies continue to show well with a minimum of seven Emperor Anax imperator present on the same date.
A Garganey Anas querquedula was present from the 15th remaining until the 21st at least on South Marsh East, while small numbers of waders were present each day.
