An uncommon yet widespread daytime flying moth in Yorkshire is the Chimney Sweeper Odezia atrata. It inhabits grassy meadows and is locally distributed throughout most of Britain but is fairly common near me. The single generation flies in June and July, the larvae feeding mainly on the flowers of Pignut Conopodium majus.

Eight people attended this workshop in addition to Mike Denton
and Darren Mann, who undertook the practical demonstration and assisted
respectively, along with Dmitri Logunov who hosted the event.
Mike briefly outlined the equipment and materials needed to
perform dissection on specimens stored in alcohol or which had been sufficiently
'relaxed'. He then performed a series of dissections on male and female beetles
before a general discussion and informal question and answer session ensued.
Darren
also demonstrated how to clear dissected samples in potassium hydroxide before neutralising in acid alcohol (70%
propanol alcohol with a drop of acetic acid in it) and then placing in diluted
alcohol (70%). The attendees then had three quarters of an hour to practise
dissection techniques themselves before lunch. By 2pm we had all reconvened in
the lecture room to continue practising on specimens supplied by Darren and
other attendees. Several participants even began working on our own specimens,
some of which were then referred to Mike or Darren to confirm identification or
suggest literature to refer to once they'd returned home.
All the attendees appeared to have thoroughly enjoyed the
day and left with new found confidence and skills to perform dissections
themselves. Profound thanks goes to Mike, Darren and Dmitri for
providing their time, experience and encouragement for the workshop.
A quick walk around Prince of Wales Park this morning produced honeybees and several bumblebee species including Red-tailed Bombus lapidarius, White-tailed B.lucorum, Buff-tailed B.terrestris and Garden B.hortorum. There were also a couple of Tawny Mining Bee queens on the Bilberry.

A problem with my PC has lead to few posts being published over the past year but I have finally managed to get the following photos uploaded from my recent visit to Skipwith Common National Nature Reserve. I specifically went there to try and find Adders but after searching all morning, it wasn't until the afternoon when one suddenly appeared, crossing the footpath in front of me.
