Mynydd Caerau (west) [SS8794]

 A little cooler today at 28c, so continued my " cooler up the mountains" theme and recorded another 32 species today. New for the year taking me to 95 species for the year were Epistrophe grossulariae, Leucozona glaucia, Leucozona laternaria, Melangyna compositarum and Helophilus hybridus. Other highlights included Eupeodes lapponicus, Cheilosia vernalis and Eumerus funeralis. Most numerous species was again Meliscaeva cinctella (40),

Not many other insects to report except for 10 Large Skipper.

Gilfach (west) [SS8487]

 Very hot today [30c] so wasn't expecting much hoverfly activity, but some of the shaded areas containing Hogweed and Bramble were quite busy with feeding insects. So surprisingly I recorded 34 species. New for the year were Platycheirus angustatus, Scaeva pyrastri and Eupeodes lapponicus, taking me to 90 species for the year. Other highlights included Dasysyrphus albostriatus (5), Cheilosia vernalis (2) and Eupeodes corollae (8) which I believe were possibly migrants as this area rarely sees them recorded. Most numerous species was again Meliscaeva cinctella (45) and Cheilosia impressa (40).

Other insects included two Red Admiral butterflies, an emergence of Harlequin ladybirds, Violet Ground Beetle and an Angle Shades caterpillar.

 Been off the net for a while, but now all sorted. June was a poor month for hoverflies after a bright May. July started well with big numbers of certain species emerging like Meliscaeva cinctella (230) at Garnwen, So hears a few photos until I start reporting regular again,

Chrysogaster solstitialis

Meliscaeva cinctella

Merodon equestris

Spelter

 The weekend has been a bit of a washout, but I did manage a few hours between the rain showers at Spelter. New for the year was Scaeva selenitica and also new for the 1km square which is now on 73 species. I haven't recorded here in June and July so a couple of visits should prove fruitful. The area is the best place for Wild Parsnip in the valley so fingers crossed. Other highlights included Xanthogramma pedissequum, Merodon equestris (rosy tipped ssp.) and Myathropa florea -which is only my second record of the year for this otherwise common hoverfly. Xylota segnis (14) was the most common hoverfly.

Broad-bodied Chaser was the first Dragonfly of the year along with Azure Damselfly joining the Large Red Damselfly. Gorse Shieldbug was also noted as well as the Alder Gall mite - Aceria nalepai and the long-legged fly - Argya diaphana.

cars knackered

 Car spluttering on the weekend, 2 fuel injectors gone, supposedly a common fault on Insignias but it took 11 years to happen. Anyway fixed now for a pretty price of £300. So Monday was the last day of dry weather for a while, so had to get out, with Blaencaerau the obvious choice again. I recorded 37 species of hoverfly in a little over 3 hours. Ground Elder now in full bloom as well as most of the Bramble. New for the year were Eupeodes latifasciatus and Volucella pellucens. Other highlights included Chrysogaster virescens,  Pipiza austriaca and Volucells bombylans. Most common species was Syritta Pipiens (27).

Blaencaerau

 I've had a chest infection of some sort for the last five days, but now it has subsided. So I felt strong enough for a walk. Blaencaerau again produced a 40 species day, with lots of the larger and more colourful species emerging probably due to the fact that the Ground Elder and Bramble are starting to Blossom. Five new species for the year made this May my highest number of species for May (currently 74) meaning I have reached 80 species before June. New for the year were Chrysotoxum festivum, Parasyrphus annulatus, Parasyrphus vittiger, Anasymia contracta and Volucella bombylans. Other highlights included yet more Platycheirus tarsalis (recordyear), Sericomyia lappona and Microdon Myrmicae agg. Most numerous species was Melanostoma scalare (35). Looking at the forecast I should be able to get out one more time before June.

Caerau

 A walk round Caerau on Sunday just before the rains came in got me 26 species. Highlights included 3 more new for the year in Platycheirus granditarsus, Melanogaster hirtella and Chalcosyrphus nemorum. Other species seen were Platycheirus tarsalis, Cheilosia fraterna and Merodon equestris. The most numerous hoverfly was Melanostoma scalare (35).

hoverflies from last week

 Fine weather continued through the week, so I had visits to both Blaencaerau (45 species) and Gilfach (west) (27 species). Hawthorn is now starting to fade after an early blossom. The Blaencaerau visit was a May record for number of species in a day. Another 10 new for the year species takes me to 70 for the year. Between both sites highlights included Platycheirus tarsalis, Chrysotoxum Cautum, Melangyna cincta (my 3rd record only), Sericomyia lappona, Erizona syrphoides and Microdon myrmicae/mutablis agg. Commonest hoverfly was Sphaerophoria sibirica (65).

Myopa testacea

 Conopid flies are usually difficult to identify especially Myopa, but I think I got this one just right.

Following the identification key, this one comes out quite easily to Myopa testacea

weekly round up

 With the fine weather continuing I visited Lletty Brongu woods (27 species) and Spelter (28 species) this week. New for the year include 15 more species taking me past 50 for the year. Highlights included Criorhina berberina, Merodon equestris and Didea fasciata. Most common species being Melanostoma scalare (57).

Blaencaerau

 With all the fine weather, some tree blossoms are flowering earlier than normal, like Hawthorn and Rowan, so there has been a big increase in hoverfly species for the time of year. New for the year are coming thick and fast. At Blaencaerau today there were 25 species recorded of which 10 were new for the year. Highlights included Platycheirus tarsalis, Chrysogaster virescens and Neoascia meticulosa. Most common hoverfly was Platycheirus albimanus (29). If the weather continues May will be a good month.

Cheilosia fraterna

Xylota segnis

Chrysotoxum arcuatum

Crab-spiders are out in force, with hoverflies falling victim like this Syrphus ribesii and also Syrphus torvus, Cheilosia impressa, Cheilosia vernalis and Cheilosia variabilis.
