Over the last week I have been reviewing the valley list to bring it in line with records held by the hoverfly recording scheme (official records) who kindly sent me a data set for SS88 and SS89. There were a number of discrepancies and I have had to remove three species from our list - details below.
1. Cheilosia Grossa - a good photograph or specimen is required for identification, we could provide neither so species removed from list. It would be scarce for this part of the UK.
2. Eumerus funeralis - a specimen is required for identification. Photographs taken can only show the family level aggregate, so again this species has been removed from the list, but kept as "Eumerus species".
3. Pipiza virens - a specimen is required for identification as it can't be done from photographs, all the valley specimens for Pipiza have turned out to be Pipiza viduata. Pipiza virens is not expected in this part of the UK. so removed from or list.
All other species on the list have either been confirmed by specimen or photographs. There have been no species to add to the list and any record errors have been rectified for the valley in the data set .This means the valley list now stands at 131 species. I have altered the lists as appropriate on the right hand side of the home page.
