Garnwen this afternoon just as the rain stopped

Had a little stroll along the forestry track and a little look at the field full of buttercups on right hand side for some hoverflies. It was a slow start as it was still raining a little bit and very cloudy but still good numbers of Episyrphus balteatus that seemed to be everywhere despite the weather. As the weather cleared i came across my first Scaeva pyrastri of the year in the long grass just off the track. A little further along i came across what i thought was the other migrant species of Scaeva selenitica. It was only when i got home and looked at the photo's on the computer that i started to question the ID of the Scaeva selenitica as it didnt look right to me, but after looking at many images of other species i just thought that maybe it was a weird looking Scaeva. After posting the images the Admins on the UK hoverflies page instantly noticed that it may not be a Scaeva but actually a Eupeodes species and Eupeodes lapponicus was mentioned to my surprise. But this is a complex species and probably a specimen is needed to get 100% ID. But still glad i made the effort to get out on such a poor day weather wise. Once the rain stopped and the sun started to shine hoverflies were out in force on the buttercups with 200+ Episyrphus balteatus 50+ Meliscaeva auricollis. A nice black form of Volucella bombylans and a very unusual clear winged Eristalis rupium was nice to see also. On another note 2 Sicus ferrugineus were nice to see also

 Eupeodes (lapponicus)? waiting for confirmation if possible

Highlights from yesterday and today.

    Cream spot tiger, Dunraven. First site record I think.

    Portevinia maculata. Good numbers of these on the Ramsons at Dunraven.

    Hairy dragonfly emerging at Kenfig pool.

    Microdon myrmicae/mutabilis. Pengwern common, Gower. Probably Myrmicae due to habitat and
    distribution factors, but can never be sure from a photo.

   Marsh fritilliary, Pengwern common, Gower.

Nemopoda nitidula

This Nemopoda nitidula was marching along the bramble leaves near Maesteg cemetery 

Maesteg cemetery

I've been visiting the public footpath at the back of Maesteg cemetery the last 2 weeks to see what hoverflies are visiting the sycamore trees that are in flower there, and i was blown away by the amount of different species that are flying back and fore the sunlit area late afternoon. Criorhina species are not the easiest species to come across, as an example i only came across C.floccosa once last year and that was my only encounter ever, so it was nice to have my second sighting earlier this year at the sewage works in llangynwyd. However after visiting the cemetery area the past few days i managed to log a new species for the valley list in C.berberina followed by C.floccosa and C.ranuunculi in the same day in the same spot which is pretty amazing Martyn managed to get C.ranuunculi for the first time earlier in the year after a few attempts to locate it in its traditional old oak wood habitat over the Darren woods. Following that i also managed to find another addition to the valley list in Rhingia rostrata after checking almost every R.campestris that i've come across the past few years in hope of finding one the main ID to look for between the two species is the dark edge that runs along the abdomen as shown in images below. Other hoverflies of note that i came across in the area are Epistrophe nitidicollis and Platycheirus tarsalis

 as you can see R.rostrata above lacks the darkened edge of R.campestris below

Ant species Negro Ant - Formica fusca/Formica lemani

I came across this Ant on edge of forestry clearfell i'm assuming its one of the two names above its a wood Ant but which one i'm not sure because the 2 are very similar in appearance i've added it too Irecord to hopefully get a proper ID but not sure if it can be seperated from a photo

 (confirmed as negro ant) formica fusca

Maesteg Cemetery (Criorhina berberina)

At last i've managed to get a photo of Criorhina Berberina (new addition to the valley list) after 2 or 3 sightings in the last 2 years without managing to get a photo for confirmation i came across this female sitting on bramble leaves at the back of the old council yard in maesteg cemetery
