Garnwen

A bit murky today, but plenty of hoverflies about with the blooming Angelica, Black Knapweed, Common Fleabane, Hemp Agrimony and Common Ragwort providing ample food source for 450 hoverflies of 26 species. New for the year was Cheilosia vernalis, highest counts were Eristalis pertinax (100) and Cheilosia impressa (60). Good records included Xanthogramma pedissequum (1) and Eristalis rupium (1).

Butterfly numbers are still on the low side, while other insects noted were Tachina grossa and Stictoleptura rubra.

 Tachina grossa - another contestant for UK's biggest fly
 Stictoleptura rubra
Cheilosia scutellata - now out in big numbers
