Common Carder Bees are just that- pretty common wherever there are flowers to feed from. We get many in the garden, especially using their long probosces to feed on the Pulmonaria and other long-tubed flowers. Carder Bees have darker thoraxes the further south they are found, and the Queens are bigger and brighter coloured than the later-emerging males. As with all Bumblebees, the Queens are the only ones to over-winter, emerging in early spring to find nests in cavities, old mouse-holes etc. They produce around 200 female drones to look after the eggs and nest, the males foraging for food– you can often see their pollen baskets laden with pollen as they rapidly
visit flower after flower before returning to the nest. Conditions: A cool, breezy (south-westerly) and cloudy, dry day. Temperature: Max 13- Min 8c.
