Gnashers

Managed two visits yesterday - a "routine" visit during the day and an evening session to put out the moth trap (to no avail, it turned out).

The evening first - an interesting one, despite the dropping temperature, and there was plenty to see on tree trunks. Tree slugs, earwigs and woodlice were more evident, allowing me to round out my standard woodlouse list with Oniscus asellus. 

Also another Dromius quadrimaculatus, the arboreal and nocturnal ground beetle which I always expect to see on a tree trunk somewhere.

The first moth of the year, at last, was this Chestnut low down on a tree trunk

A routine find on vertical surfaces, especially trees, is the harvestman Oligolophus hanseni. This is a fairly recent addition but I've found it during the early months in various places now.

More of a  surprise was this Hawthorn Shieldbug

The best for me of yesterday was during the day, though, with this Pachygnathus clercki. This isn't new to the reserve, but it was new for me. Cracking set of gnashers

Giving me the ich - Scambus elegans

On a nocturnal visit to Cullaloe this week I spotted what I thought was a spider dangling from a Willow branch. Slipping the rim of the net under it I scooped it - only to find a female ichneumonid wasp in the net. No spider, though there could have been one which has been saved from a sticky end.

Early investigations made me head for Pimplinae and - yippee! - I have a key. It has literally taken me all day on and off to unpack the vagaries of wasp key glossary madness (errr, I mean I was working from home). I ended up at Scambus elegans, and, unbelievably, this seems to be correct. There are 4 records on NBN. If it's univoltine and mature in February that's no wonder, though. What kind of idiot's looking for Ichneumons in February?

This happy idiot :)

Subtle elegans-ness

Short numbers note: despite spending years looking at Cullaloe and a whole year hammering it for a 1K challenge only two years ago I've seen in the first 7 weeks of 2021: 14 new diptera, 4 new spiders, 23 new beetles, 8 new bugs and a new wasp. This has to be, in part, from ignoring everything that isn't an invertebrate. There must be some sort of lesson there.

Here's some old wasp

Buggin

A nocturnal visit (well, 7pm anyway)  added a few species to the year list, but also this Nabis ferus to the reserve list as bug #80. Interestingly this is the 2nd species I've added this year which I found in the Cullaloe Hills in February of last year. I can't explain why in all the sweeping of the same area during spring-autumn I've never knowingly seen this one before. However, this is the first year the "flower meadow" hasn't been mown. not sure that will be good for the botanical site monitoring later. Be interesting to see how the area responds to not being mown.

2021 bug #13, 2021 new bug #8 (!)

Reserve bug #80

More spots

A species I always go looking for when the nights get milder. Can almost always find one after head-torching a few tree trunks

2021 beetle #66, Dromius quadrimaculatus

Already listed, but amazing to see the Triplex aenea out to play on the dead Horse Chestnut and associated fungi

No apparent damage - spore feeders?

A quick tap over the sweep net

Spotty Stenus

Stenus bimaculatus is a beetle I found in the Cullaloe Hills last February, but it was nice to see it show up on the reserve as the 65th beetle species of the year. It's the 11th species of Stenus for the reserve and the 6th this year. I knew it was going to be new because none of the other 10 species are spotty.

It was in the eternally-giving grass pile near the car park. If I had only skimmed the top layer of that pile today, now that it's warmed up. I could probably have half the species re-recorded! It was tempting to take a video of how much movement there was in the tray.

Nymph-tastic

Easy, tiger. Went pond dipping with the boy at lunchtime and we didn't fare very well in diversity. However, spying a couple of nymphs with three tails had me reaching for a pot, and excitedly hauling the brand new "Pictorial Guide to British Ephemeroptera" from the shelves. I had only just noticed that nymphs were keyed too, so I was hopeful this might just work.

Unlike many other things that I thought were difficult (and they were) this turned out to be easier than expected. Beginner's luck, no doubt. Gills at the side of the body, streamlined body, antennae relatively long -> Baetidae. Lovely. "Tails" unbanded, centre one shorter -> 5 spp. of Baetis. O.K....

Couple of species out of range; check the others. Baetis rhodani ... gill 1 and 7 same size - yup, gill edge with spines as well as hairs - yup. Spines separate B.rhodani from all other Baetis. Awesome! And habitat is spot on in stony-bottomed fast moving stream. My first ever mayfly keying, and it's only February. Happy days.

Baetis rhodani is the 48th new species for the reserve this year and the 32nd new species for me (from here)

New Fife beetle

On a random whim today I headed for leaf litter sieving in the woods. The ground's been a bit warmer and, honestly, I was hoping to pick up a spider or two. Of course when you start throwing leaf litter around anything's possible.

What I didn't expect, I think reasonably, was a big shiny dollop of histerid beetle to gleam from the gathering humus layer in my tray. I love these things, but I've only ever seen one species. In two places. I've been dreaming and scheming of baited pitfall traps and bottle traps, of sieving poo etc., in the hopes of seeing maybe one or two. I still am, but nt sure what may be around here. There's certainly no shortage of poo and I'm happy to provide carrion. I guess they are so shiny because they want all that, erm, stuff, to slide off them like a shiny wotsit, as the proverb says.

Anyway, that was a long way for a short cut. This is Margarinotus neglectus, The Lonely Clown (awww). There are no dots in the new Histeridae bookie, so I'm claiming it as new to county. 

2021 beetle #63, Margarinotus neglectus, new to me, new to Cullaloe, new to Fife.

Gleaming underside. Fabulous.

Pygidium-sh bits (the back end)

Another beetle I grabbed from the filter beds the other day, with a minor sense horror, turned out to be Helophorus obscurus, which I actually thought it might be. However, it had the good graces to be male and to allow me to extract the necessary bits to secure the ID.
