Bumbler bees and foxgloves

Source: Bumbler bees and foxgloves

Guard hairs deter smaller bees from entering the foxglove flower. The reason being that the flower is effectively selecting large bees to pollinate it, particularly long-tongue species, such as Bombus hortorum, which can reach deep inside the flower to get the nectar.

I am a retired entomologist with a background in quarantine pests and invasive invertebrates. I studied zoology at Imperial College (University of London) and did a PhD on the population dynamics of a cereal aphid (Metopolophium dirhodum) in the UK. I spent 5 years with the British Antarctic Survey studing cold hardiness of Antarctic invertebates and 17 years with the Food and Environment Research Agency. My main interests now are natural history, photography, painting and bird watching.
