Welcome to the Llynfi valley nature blog, which will feature all aspects of wildlife found in the valley and surrounding areas. Sightings from further afield will also be included, along with postings of highlights from the past.
Came across this sawfly species which was formely known as (Abia fasciata) but is now known as Zarea fasciata it's a very impressive sawfly at first i thought that it was some sort of bee species but i couldn't think of any species that had these chocolate brown patches on the wings so i started to think its got to be a sawfly species again feeding on the hogweed along the forestry tracks
I came across this tachid fly whilst out checking the hogweed for hoverflies there has only been 105 records in the whole of UK and Ireland with just 8 records for wales and now a first record for the valley and the nearest records are Rhoose and Merthyr (correction Martyn has already logged this species in Caerau) so this is the second species to be found on opposite sides of the valley, and i think it likes forestry plantations on upland areas
A nice Volucella Zonaria was feeding on bramble blossom on side of tarmac pavement that runs upto the junction at Maesteg cemetery from Cemetery road along with a nice Microdon and my first Tachina Grossa of the year on the open fields by school. I decided to do a trip outside the valley over the weekend to kenfig pool and parc slip which turned out to be a good decision because i recorded my first sighting of Eristalinus sepulchralis at parc slip today. Other insects of note were 2 Banded General that were feeding on the Hogweed
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
black form of Volucella bombylans
Eristalis rupium without the chocolate shading you would normally see on the wings
