Cwmfelin Park

 Temperatures reached 15c today with very little wind, so went to visit the Blackthorn hedge at Cwmfelin Park which was in full bloom and dripping with spring hoverflies. Melanostoma mellinum (1m) and Epistrophe eligans (1m) were new for the year. Platycheirus albimanus (75) and Eristalis pertinax (45) were the most numerous. Other highlights included Parasyrphus punctulatus (3f) and high counts of Eupeodes luniger (4m, 3f) and 10+ Eupeodes not specifically ID'd. Also large numbers of Spring Syrphus (40+) of which Syrphus Ribesii (1m, 2f) and Syrphus torvus (7m, 2f) were checked in hand. 

4 species of butterfly were on the wing headed by 3 Brimstone, 3 species of mining bees - Clarke's, Gwynne's and Tawny as well as 60 Honey Bee. Bee-flies were numerous and a few 7-spot and 10-spot Ladybirds were basking on the larger leaves.

Only one singing Chiffchaff was noted and there were lots of fresh Mole hills about.
