Saltmarsh meets North Elmham, a scarce barkfly, a new bug and a new beetle

2018 seems to have been an exceptional year for saltmarsh species making their way inland.  I have already blogged about a surprise Silver-streaked Case-bearer Coleophora limoniella that turned up here on 23rd July, one of 3 inland records in July of a species that had never turned up inland in Norfolk before.  I've also already blogged about a Saltmarsh Plume Agdistis bennetii at Derby Fen in June, and very soon I'll be writing about another one at home - again in a year when other observers have also recorded unusual numbers of these inland.  Well there was one more saltmarsh surprise in my North Elmham trap on 3rd August - a Saltern Groundling Scrobipalpa instabilella.  This is another very unexpected record - until this year the furthest inland records in Norfolk were at Catfield Fen in the Broads and at Dersingham.  There was another at Derby Fen on 8th August but this one is by far the furthest inland record there has been in Norfolk...

Small Waved Umber was only my second here, indeed only my third anywhere, and Birch Ermine Swammerdamia caesiella was also only my second here.

Mayflies included what I think is a Pale Watery Baetis fuscatus, but although I identified this at the time and let it go I omitted to add it to my notes or caption the photo, so I'm now having to identify it again from the photos which I never like doing with mayflies.  Also 2 Blue-winged Olives Serratella ignita.

There was a good selection of green and brown lacewings: 2 Chrysoperla carnea, 2 Cunctochrysa albolineata, Dichochrysa flavifrons, Hemerobius lutescens and Micromus variegatus.

Among the caddisflies Athripsodes albifrons was new for the year; there were also 2 Ithytrichia lamellaris, 2 Hydropsyche pellucidula, 3 Hydropsyche siltalai, Limnephilus auricula and 1-2 Athripsodes aterrimus.

The best of the bugs was Atractotomus parvulus, a new species for me.

Deraeocoris lutescens was also new for the year, and other bugs were  Birch Shieldbug, Blepharidopterus angulatus and the leafhopper Empoasca vitis.

This barkfly was eventually identified as Valenzuela piceus, a scarce species according to the National Barkfly Recording Scheme.  There are only 9 records on NBN for the whole country, the nearest being in the Cambridge area, but that doesn't always mean a great deal as barkflies are one of the taxa that aren't well represented in NBN.

Among the beetles there were a dozen or so Bradycellus sp.  Usually these turn out to be Bradycellus verbasci and one of the two I retained did just so.  As soon as I looked at the other one under the microscope I had a feeling it was a different species and so it proved - my first Bradycellus harpalinus.  Other beetles included an Ophonus sp. that I couldn't quite resolve and another Aphodius rufipes.

A quick visit to the meadows produced Common Grass-veneer Agriphila tristella, Common Plume Emmelina monodactyla and a 7-spot Ladybird.
