Mainly sunny afternoon with a gentle westerly breeze blowing, temperatures around 20 degrees. Several Keeled Skimmer Orthetrum coerulescens males were active around the bog, though no females were found. Golden-ringed Dragonfly Cordulegaster boltonii were also present in good numbers. Other species noted included Large Red Damselfly Pyrrhosoma nymphula, Southern Hawker Aeshna cyanea, Common Darter Sympetrum striolatum and Black Darter Sympetrum danae.
A few butterflies also on the wing with Small Heath Coenonympha pamphilus, Red Admiral Vanessa atalanta and a Small Copper Lycaena phlaeas all noted. Other miscellany included Heather Colletes Colletes succinctus, a large colony of this solitary bee in the river bank. Solitary comes from the fact that they nest as individuals, even though they occur in large aggregations. Bog Bush-cricket Metrioptera brachyptera was another nice find around the margin of the bog. Several Common Lizard Lacerta vivipara and Common Toad Bufo bufo were also noted, along with Bog Hoverlfy Sericomyia silentis.
