Despite August ending with cool overnight temperatures, moth trapping at Tophill Low NR, East Yorkshire provided a trio of surprises. An Oblique Carpet Orthonama vittata was the highlight, but not the only new addition to the site list as Vine’s Rustic Hoplodrina ambigua and Cochylis atricapitana were also collected at light for the first time in Tophill history.
The weekend saw 600 moths trapped taking the total to over 9000 for the year and the species list up to a fantastic 354.
The best of the birding involved a Black-necked Grebe Podiceps nigricollis on D reservoir, which also held a minimum of 4 Mediterranean Gull Larus melanocephalus on September 1st, while a female Pintail Anas acuta was present at the southern end of the site.

This Southern Hawker Aeshna cyanea was one of the few noted over the weekend. Migrant Hawker A. mixta, Common Darter Sympetrum striolatum and Ruddy Darter S. sanguineum were also present in small numbers, while 11 Common Blue Damselfly Enallagma cyathigerum were something of a surprise after the previous weekend blank.
Windy conditions didn’t provide great opportunities to observe butterflies, but at least three Clouded Yellow Colias croceus were still present at the southern end as August drew to a close.
