Hornet Rove Beetle and other beetles from last year

As I begin to embark on a series of posts covering a summary of 2019's observations (having completed zero blog posts about them during the course of the year), I discovered that I still have an unpublished post relating to 2018's records.  It concerned a number of beetles that I had set aside having found them too difficult to identify at the time.  Coming back to them in 2019 I managed to make a bit more progress.

They include what now becomes my first Curtonus aulicus on 12th April, and remains my only record for the garden.

Two tiny Meligethes pollen beetles beaten from some blosson at Bittering on 13th April proved to be different species.  One was what I understand is by far the commonest Meligethes aeneus but the other was more interesting: Meligethes brunnicornis.

Another new beetle was Harpalus latus, from the track by the dunes at Horsey.

I really struggled with the keying of two similar (though not identical) beetles, one from Horsey on 18th April and the other from St Faith's Common later the same day.  In the end I'm pretty happy they were both Amara familiaris.  Another new species for me, albeit apparently very common.

Several more pollen beetles proved to be Meligethes aeneus but one that was attracted to a Red-belted Clearwing pheremone lure at home on 22nd April turned out to be the much scarcer Meligethes pedicularius.  Shame I only got this rubbish photo!

I'd managed to identifiy one of these from the Cathedral Meadows so not sure why I struggled so much with this one, but anyway, this was my first Enochrus melanocephalus for the garden.

I initially had some difficulty keying this large rove beetle.  Superficially a little bit like Devil's Coach Horse Beetle but some pretty obvious differences from that and its congeners, not least the hairless and more-or-less shiny head and pronotum.  Eventually I figured out what it was.  Actually it should have been pretty obvious from the start - it's a Hornet Rove Beetle Velleius dilatatus.  That's actually a pretty decent record - undoubtedly my best beetle to date.  I have checked it with Martin Collier the county recorder for beetles and not only does he agree with my ID but he also confirmed that it's only the fourth record for Norfolk!  I imagine that the fact that it was an excellent year for Hornets may have benefited the Hornet Rove Beetle as well?

Eyed Hawk, a new froghopper and other bits and pieces

There were no stand-out highlights in the moth trap on 3rd September, though an Eyed Hawk-moth is always nice, especially after things have slowed down in the autumn.  The others were Light Brown Apple-moth Epiphyas postvittana, Garden Rose Tortrix Acleris variegana, 3 Common Marbles Celypha lacunana, 4 Common Grass-veneers Agriphila tristella, Elbow-stripe Grass-veneer Agriphila geniculea, Common Plume Emmelina monodactyla, 2 Brimstone Moths, 2 Light Emeralds, 12 Large Yellow Underwings, Lesser Yellow Underwing, 3 Setaceous Hebrew Characters, Square-spot Rustic, Nutmeg, 3 Common Wainscots, 5 Flounced Rustics, Rosy Rustic and Straw Dot.

At home that night Pine Carpet was new for the year.  Other highlights were Beech Pigmy Stigmella hemargyrella and Thatch Neb Bryotropha basaltinella. The former was my third this year of a species I hadn't previously recorded here and the latter was my fourth this year of a species that until this year hadn't been recorded anywhere else in Norfolk.

The following night the leafhopper Kybos betulicola appeared in my study

In the moth trap there were two new moths for the garden year-list, Brown-spot Pinion and Lunar Underwing.

A White-shouldered Smudge Ypsolopha parenthesella was the only adult moth found but vacated leaf-mines of Scrubland Pigmy Stigmella plagicolella and 2 Apple Leaf-miners Lyonetia clerkella were also seen.

Other insects included 2 7-spot Ladybirds, the hoverfly Myathropa florea, a Turnip Sawfly and lots of wasps feeding on ivy.  They included lots of Common Wasps, at least one German Wasp and 2 Hornets, but among them I had brief views of a Colletes bee which was very probably an Ivy Bee.  Ivy Bee was new to science as recently as 1993 and arrived in the UK in 2001, reaching Norfolk by 2014.  It is now common in many places but as hard as I tried to find one at the meadows this autumn this brief sighting was the nearest I got.  Sadly it wasn't quite good enough to be 100% sure - I believe there are one or two other Colletes species that can visit ivy at this time of year and my views were not sufficient to rule out one of them.

Shaking some Field Maple keys produced the barkfly Ectopsocus briggsi, a harvestman and 2 spiders.  The latter were I think immature, or at least I could not see enough detail in their epigyne to be able to match them to any species, but I think they were an Araniella sp. and a Philodromus sp.  My references on harvestmen are sparse but from searching the internet I'm pretty sure this one was Paroligolophus agrestis, a species I hadn't previously identified.
