Recently (yesterday as I type this, in fact), Defra, guided by several wildlife organisations, have launched a 'Call to Action' highlighting ways for the general public to help bees as part of the National Pollinator Strategy. While several of these suggestions (particularly 'leave patches of land to grow wild', 'think carefully about whether to use pesticides', and 'cut grass less often') should perhaps be aimed more at national and local government as per my last blog, they're aimed at the rest of us and the entire call to action can be boiled down to one sentence: bees need food and a home.
I work for the Bumblebee Conservation Trust (BBCT), one of the main organisations guiding Defra on the NPS, so I'd known the content of the Call to Action for quite a while. It was evident that several of the suggestions were aimed at people with land to spare (particularly 'leave patches of land to grow wild' and 'grow more trees'!), but there are plenty of us for whom owning any land is just a distant dream. My garden is actually my landlady's garden: I can get away with rummaging in the plants for interesting invertebrates but tree-planting would see me out on my ear in short order! My girlfriend lives in a first-floor flat with no garden, in an urban area of Bath - what could we do there to make things bee-friendly?

And find it they did! Less than 24 hours later a bumblebee had arrived: within a week three species of bumblebee had been seen on the flowers (common carder Bombus pascuorum, buff-tailed B. terrestris, white-tailed B. lucorum), as well as a tiny Lasioglossum solitary bee and several hoverflies (the marmalade hoverfly Episyrphus balteatus and a couple of Syrphus species). More recently a tree bumblebee (B. hypnorum) had circled without settling and a couple of spiders (the garden spider Araneus diadematus and the jumping spider Salticus scenicus) had made the windowbox home, while an tortrix micro-moth caterpillar of some sort had munched its way through several of the lavender flowerheads (just this weekend Kate found the hatched pupa sticking out of the stitched-together flowerheads so it will remain, alas, unidentified). Sadly none of June's impressive hatch of scarlet tiger moths could be persuaded to land on the flowers!
Most exciting of all, the 'bee hotel' was colonised almost instantaneously by red mason bees (Osmia bicornis (=O. rufa)), so next spring the garden will be able to supply its own home-grown wildlife. Food and a home - it's really not that hard to help the bees...
