Just wondered if anyone has records of Bombus monticola queens emerging in March / early April and where from - of particular interest would be Shropshire / Derbyshire / Yorkshire records.
I've scheduled a survey - weather depending - to look for Bilberry Bumblebee queens on the 10th April, though I have only seen workers on bramble and Common Cow-wheat in the targeted area, in June last year.
There are records of workers on ling in August from the same area.
There is one record of a queen / worker on willow in spring from a few years ago, though to my knowledge no other spring records anywhere in the areas with records.
The targeted area is on the fringe of the West Pennines in central Lancashire at around 500 ft above sea level, though relatively sheltered as a less intensively farmed area - there is a range of willows inc. the Goat - Grey spectrum, Eared Willow, Osier and Crack - White sps.
Cheers in advance,
