[SS8691] Mynydd Bach (south) - 100 species for the 1km square

 Mynydd Bach (south) better known as the "cemetery 1km square" has become the 5th - 1km square in the valley to record 100 species following Paul Tabor's finding of a Cheilosia grossa on Saturday. Besides the cemetery the square contains some meadows, moorland and a coal tip reclamation area with some woodland.

The site itself was quite hard to work and was visited over 50 times. Unlike previous 100 species 1km squares the number of hoverfly species per single visit remained relatively low with peaks at week 20 (late April) and weeks 32-35 (August). One plus for the site is the cemetery has quite a lot of Ivy and records continue right up until week 45 (early November) while other sites were done for the year. The record of Eristalis similis is still the only record of that species for Wales.
