This years record haul of Longhorn beetles continues, this time Leptura quadrifasciata at Cwm Drysiog, a small woodland valley between Bryn and Maesteg.
Also this rather noticeable tachinid fly - Tachina Fera
Hoverflies are becoming less noticeable, with less and less flowers available, managed 10 species today with the best being Sericomyia silentis.

Rhingia campestris [hoverfly] - an unusually dark specimen
Chrysotoxum arcuatum [hoverfly] - ID features include the fat pear shaped abdomen with the yellow on the third tegrite angling downwards and the length of the1st and 2nd segments on the antennae combined are shorter than the length of the 3rd segment.
Green Shieldbug - 2nd instar - quite a few of these about today.

Didea fasciata - new for valley @ Garnwen
Seen one before in 2007 but didn't have a camera so I scrubbed that record because I didn't at the time confirm the yellow halteres [remains of the diptera hind-wings (they used to have 4 wings but now evolved into only two) which now acts as an organ of balance. There are three species of Didea but only Didea fasciata has yellow/pale halteres, while intermedia and alneti (last recorded in 1989) have a black haltere and neither has been recorded in Mid or South Wales. To identify a Didea you first have to confirm the loop in the wing of the R4+5 vein which is unusual amongst yellow and black hoverflies. Secondly, the oblique abdominal yellow markings gives Didea a very distinct and aggressive appearance. Another useful feature is that Didea has all black hind legs. Now we know it is a Didea we can check the halteres which in the case below can clearly be seen to be yellow/pale making it Didea fasciata.
Haltere can be seen where the wings meet the abdomen
Aggressive looking species due to the yellow abdomen markings
Another view of the haltere and also the all black hind legs

New hoverfly for Caerau
Cheilosia bergenstammi is a difficult to identify hoverfly, so multiple angle shots are needed. Always associated with Ragwort in Autumn as it is the larva's food-plant. There are quite a few Cheilosia that look very similar. The round, flat orange antennae with hairs on eyes and feeding on Ragwort [autumn Cheilosia prefer white umbellifiers] is a good indication that this is "bergenstammi". The tarsi are extensively pale and the tibia are usually orange with a black ring. Furry type Cheilosia can also be eliminated. A combination of all the above features can then rule out the other Cheilosia. I was pretty sure it was bergenstammi, but had an expert to confirm just in case - which he did.
