Even though October is drawing to a close, on warm days the bees are VERY busy.
If you look closely at the ivy, you can see it covered in insects busy at work on the ivy flowers. Not only honey bees, but wasps, flies and bumble bees. All going about their work gathering or consuming the produce of the ivy flower.
The Ivy flower is quite easily overlooked, but is a valuable source of nectar and pollen for the bees. Especially at this time of year when there is not much more forage around. This is one of the last chances for the bees to gather last minute stores.
