|Current 'black holes' as of 2015|
2014 saw around 50 tetrads, that previously had absolutely no butterfly records, being filled in. Hopefully we can fill in a similar number this summer. If you would like to know exact boundaries of an empty square, please get in touch.
In addition, so many squares have only a handful of records, so wherever you are in the county, please keep a note of what you see if you can.
As detailed in the post below, butterflies are already flying this year. Here's hoping for a good hot summer - I'm hoping we continue to have the most records for a single year. Any questions relating to recording your butterfly sightings, just drop me an email.
