An overcast morning with a fresh westerly blowing, temperatures around 19 degrees C. Conditions were a bit challenging with the wind making photography difficult for invertebrates. Single Black-tailed Skimmer Orthetrum cancellatum and Four-spotted Chaser Libellula quadrimaculata were the only larger species noted, the dragonfly ponds really exposed to the wind today so devoid of activity. The recently emerged Common Darter Sympetrum striolatum are now starting to spread out around the reserve and are becoming more obvious. A female Emerald Damselfly Lestes sponsa was along Dryham Lane with Azure Damselfly Coenagrion puella, Blue-tailed Damselfly Ischnura elegans, Common Blue Damselfly Enallagma cyathigerum and Red-eyed Damselfly Erythromma najas all noted at varying points around the site.
Only a handful of Butterflies active, Ringlet Aphantopus hyperantus being the most numerous species. A second brood Large White Pieris brassicae was along the Northern Path in a brief sunny spell. The only other species recorded were Common Blue Polyommatus icarus, Large Skipper Ochlodes sylvanus,
Meadow Brown Maniola jurtina and Speckled Wood Pararge aegeria.
Highlight of the day however was Corizus hyoscyami (NFY), one of the True Bugs. Although I’ve seen this species briefly before, this is the first time I’ve managed to photograph this attractive species.
Beetle-wise the full list is detailed at the foot of this post, only Cantharis nigra being new for the year.
Of the Hymenoptera three species of Bumblebees were active, Common Carder Bee Bombus pascuorum, Early Bumblebee Bombus pratorum and Tree Bumblebee Bombus hypnorum. A couple of Sawflies were also noted, one appears to be Rhogogaster chlorosoma (NFY), the other not possible to get to species level.
On the Diptera front Coremacera marginata and a Thereva sp. were new for the year. Of the Hoverflies a Pipizella sp. was along Dryham Lane and Volucella pellucens was along the Western Path both being NFY. Other species recorded listed below.
