This is your occasional reminder, if you are interested in spotting flying insects, that it is a very good idea at this time of year, when the various willows (Salix species) are coming in to flower, to spend a little staring at these trees. That is partly how I came to find so many butterflies yesterday. Several of the Brimstones I saw, in particular the two females that were feeding up prior to egg-laying, and the beautiful Small tortoiseshell were all found initially on willow flowers.

The fluffy yellow flowers were also providing much needed sustenance for a variety of flies, for honey bees and hoverflies. Due to their larger size, I was also able to see at least two species of bumblebee, Buff-tailed (Bombus terrestris) (left below) and Tree bumblebee (Bombus hypnorum) (below right).

I was amazed today at Cosmeston to hear a buzzing sound and then watch this bumblebee fly slowly past, to settle on the trunk of a nearby tree. It’s a Tree bumblebee, I think, Bombus hypnorum, a species that usually emerges from its winter sleep in March.

Yesterday I saw a Red admiral butterfly, and now today this bumblebee. It just shows how mild our winter weather has been so far.

The return of the bumblebees

As the Mary Kay Ash quote goes: ‘Aerodynamically, the bumblebee shouldn’t be able to fly but the bumblebee doesn’t know it so it goes on flying anyway.’ And flying they are, now that spring is here. The warmer weather brings the bumblebees – all queens – out of their long sleep, to begin the process of nest building and egg laying. In the past week I’ve seen several in flight and managed to get photos of two different species.

160402 Bombus hypnorum Tree bumblebee

Though it’s common in Europe and Asia, this Tree bumblebee (Bombus hypnorum) is not a British native. In fact, its ancestors only arrived in Britain in 2001. It has, however, made itself right at home and, as far as scientists can tell, is not damaging the native bee populations. It’s important we monitor its spread and population though, so please help by reporting your sightings to the Bees, Wasps and Ants Recording Society (BWARS).

160402 Bombus terrestris Buff-tailed bumblebee

The Buff-tailed bumblebee (Bombus terrestris) is often the first to be seen each year, emerging as early as February if the weather’s warm enough. Its nests, occupying old mouse and vole holes underground, can house as many as 500 individuals.

You will notice in my photo that this bumblebee has some hitchhikers. These are mites but please do not be concerned for this little creature. The mites are normal, they actually help keep bumblebee nests clean, and only in extreme cases do they affect the bumblebee’s health and welfare. You can read more here.
