Emergency
Had a rough few days doing nowt, although my part-rejuvenation has coincided
with the weather briefly perking up so perhaps I will get out tomorrow. In the
meantime, any action has been indoors.
Last year I found
a sawfly larva in the garden
that I'd have to try and rear through to confirm which species - Abia lonicera
or Abia aenea. Remarkably it survived despite being mistreated for prolonged
periods and a spell of very cold weather whilst any larvae and pupae I had were in the shed, and it emerged on Friday
26/03/2021 after being transferred to a newly acquired rearing cage. I was
hoping that would be enough, but sadly not - it appears that the adults are
not readily separable either and it's going to have to be pinned and
scrutinised more closely to confirm (by absence/presence of microsculpture on
mesosternum). There is also a subjective antennal character which I can't make
head or arseholes of. It is far more likely to be Abia lonicera; that was
apparently new to VC55 in 2018 and there are a number of subsequent records
although it's not clear that any have been properly scrutinised. There are
apparently no records of Abia aenea for VC55.
It's a funky fat sawfly either way. I fully expect that there will be more of
these, whichever species, on the front garden Lycestria bush in due course.
Today whilst on a work phone call, I spotted what appeared to be a small
micromoth on the inside of the office window, although the window was wide
open at the time. I managed to deftly pot it one handed whilst continuing the
call. It was only later when I looked at it with an eyeglass that I realised
it was one spanking looking micro, though off the top of my head I wasn't sure
which one. After a bit of literature trawling I realised it was mint-fresh and
out of season Chrysoesthia drurella, at which point my elation
turned to nagging doubt. You'll recall
I found and collected some mines
last year, but I thought the larvae had all died after leaving the mines. And
anyway, how could one be on the window if it was supposed to be in my rearing
box (which had long since been re-purposed for the Ctesias serra larvae I'm
trying to rear). The mystery and doubt would have endured forever had I not
casually looked at the said rearing box and noted something flitting about in
it - yes of course, another Chrysoesthia drurella. So not new for me or the
garden, though good to see an adult. I had a quick effort with the TG-6, not
happy but better than nothing. Anything shot with this really has to be absolutely still to get the best in-camera stacking results.
The moth trap is out tonight for the first time since Thursday; low
expectations as today has been unseasonably warm and tonight will be
seasonably cold. With a breeze.
Tomorrow I am expecting delivery of a couple of tortrix pheromone lures; there
has been a National epiphany this year with many records of multiple Pammene
giganteana to various lures for other tortrix spp. - turning it from an
absent/rare species to apparently common in the process. I've ordered lures for Grapholita lobarzweskii and Grapholita molesta. Perhaps I can add Pammene giganteana to the square list by hanging a lure off of the two biggest oaks, and re-record G. lobarzweskii later in the year.
I left my garden SKI lure-trap to fend for itself today, whilst I undertook a little 'local' fieldwork and returned to find 10x Pammene giganteana inside the trap.
It was staying quite local to the clump of gorse it was hiding behind ! Not sure, but might have seen a Goshawk, too. Acanthopsyche atra was the day's 'target' and highlight - Casta-saurus Rex !!

I'll be amazed if you didn't record giganteana tomorrow from mature oaks, mate.

We'll see - not exactly a lot of oak woodland south of the City.
Brilliant, that lost Yes album 'Microsculpture on Mesosternum VolI'
Thats a cracking little moth mind, Ive never heard of it....
Looks like it could be absent/thin on the ground up your way Stewart.

Got some nice views of Dartford Warbler, too.
;-)

I hope the warbler was very non-local!
