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.
