A look through my photo files shows me that I have taken very few images of bees this year and none at all of butterflies. That may be partly due to me being busy finishing off the pond, rather than paying so much attention to the flower borders. But the relative absence of these garden friends has been very noticeable over the last few months.
Spring wasn’t so bad. There were Buff-tailed bumblebees and Common carder bees keeping busy in the spring flowers as usual. A little later, lots of honeybees made the most of the flowers of the Ceanothus bush. It fairly buzzed at times! But when the temperatures began to climb, there certainly appeared to be less activity in the garden.
Keeping myself out of the heat probably means that I was less aware of any bees that were around. Normally, though, I would see quite a lot of them – hoverflies too. I’m more sure about the drop in butterfly numbers here. There are warm, sheltered spots in the garden that frequently attract butterflies but this year there were rarely any there.
I’ve read that this year’s ‘Big Butterfly Count’ had lower numbers recorded, despite an expected increase because of the warm weather. It is feared that environmental changes and habitat loss account for the drop. For many bees, though, the heat of this summer is suggested to have been a disadvantage. A study by US scientists has found that the larger, heavier bodied bees (including bumblebees) declined as temperatures increased, while smaller bees increased in numbers.
Does this explain why I’ve seen fewer bumblebees this year? I don’t know. All I can really do is to try to provide as much as I can in the way of useful plants and habitats in the hope that it will help both bees and butterflies.
