The onset of August has seen butterfly numbers increase due the latest emergence of this group at Tophill Low NR, East Yorkshire. The Fleabane Pulicaria dysenterica and Buddleia Buddleja spp. proves attractive with Peacock Aglais io and Painted Lady Vanessa cardui, Red Admiral V. atalanta and the Whites Pieris spp all easily seen.
Among the many Meadow Brown Maniola jurtina, small numbers of Gatekeeper Pyronia tithonus, Wall Brown Lasiommata megera and Small Copper Lycaena phlaeas can be picked out nectaring on the yellow flowers.
Brown Argus Aricia agestis was a welcome addition to the site year list. However, only two individuals could be found in early August, with one remaining until the middle of the month at least around the southern half of the site.
Wader season continues as water levels on the lagoons and marshes drop to reveal new mud – this Greenshank above was present in early August – for the latest news from Tophill Low NR, check out the blog.
Garden Tiger Arctia caja are always an attractive species – Doug Fearweather photographing this one in late July which was covered in water droplets.
Bulrush Wainscot Nonagria typhae and Fen Wainscot Arenostola phragmitidis are two of the moth species expected to be found in the reed beds at this time of year, while Canary-Shouldered Thorn Ennomos alniaria are regularly trapped alongside the occasional Small Phoenix Ecliptopera silaceata.
This Dusky Sallow Eremobia ochroleuca on August 5th is something of a site scarcity with only 15 records since 2002 to date.
This Campion Sideridis rivularis on the same date was the eighth site record since 1996 – and the first individual trapped since 2003.
Tophill’s only Scalloped Hook-tip Falcaria lacertinaria occurred in 2010 – so this specimen on August 12th was a long overdue second record.
A number of species have been added to the site list in recent weeks – The Coronet Craniophora ligustri photographed by Doug Fairweather was attracted to light overnight on July 29th, while this Butterbur Hydraecia petasitis was recorded on August 6th.
