Pollinator species sightings
As a bi-product of our research I realised that the number of species of bee that we were seeing at rosybee seemed to be increasing and so last year I started a list of all the bees, butterflies and other major pollinators that I am able to identify. It does not yet include hoverflies, flies or beetles as those are just too numberous for me to learn right now.
Here is a link to the spreadsheet which I will update periodically. Last updated April 2018 - the ones in red are newly sighted.
