These bees are being trapped in the kiosk in the butterfly meadow. Once it was noticed, volunteers took steps to fix the lid so it would not close entirely, allowing the bees to leave. They seemingly were able to get in before, but unable to leave. Not sure why they are so keen to get into this kiosk which is made of recycled plastic, not wood. Here, there are several bees which don't look too healthy, even though they had plenty of freedom to leave the structure.
