Colletes hederae - Summary of 2011 monitoring project

Colletes hederae enjoyed another year of colonisation, consolidation and advance in 2011. The northerly limits of its range were extended northward on two fronts. The first crop of records occurred in the unseasonally hot weather at the end of September, when numerous records started coming in from a suite of sandy sites to the south of Oxford, with particularly large nesting aggregations noted from Dry Sandford Pit. We also received records from Cheltenham (Gloucestershire) which represents… Read more

Colletes hederae - Summary of 2010 monitoring project

Steady expansion and further consolidation would sum up the status of Colletes hederae after another good season for the bee.

There have been many records from areas colonised in prevous years, but 2010 has seen a considerable number of new records from inland sites in central Hampshire, new records from the Reading area of Berkshire and a significant number of observations from the southernmost parts of Surrey. What is clear now is that what were (a few years ago) distinct… Read more

Colletes hederae - Summary of 2009 monitoring project

2009 has been another excellent year both for Colletes hederae in UK and our monitoring effort. BWARS has gathered data from no less than 61 10x10km grid cells this year, of which no less than 33 represent entirely new locations. A glance at the map at the foot of this webpage will show that the most exciting areas for new sightings have been in west Kent, the north Kentish coast and south Essex (the first records from north of the Thames). I have also received a good number of records from… Read more

Rob Parker of the Suffolk Naturalists' Society sent me [Adrian Knowles] the following anecdote regarding an Osmia bicolor nest which he had previously observed being covered by pine needles as part of their "tent making" behaviour:

"I returned to the King's Forest on this morning's Dingy Skipper search, and found my O. bicolor nest had grown substantially since my last visit 11 days ago. We carefully lifted the pagoda of pine needles off, and found the snail shell had a large pine kernel over the top of it, so that it was quite… Read more

1. Bombus pratorum worker flying in December 2006

From the BWARS Forum: Steve Farmer Sunday 17 December 2006

This morning (Sunday 17 December 2006) we visited the Valley Gardens at Windsor Great Park. There we saw 5 Bombus Pratorum workers simultaneously collecting pollen and nectar from Rhododendron flowers. The bumblebees were very easy to observe as the Rhododendron pachysanthum was on the edge of the path. The workers had one yellow band on the thorax but the band on the abdomen was virtually absent. Each… Read more
