Two white butterflies were in the air over the Compton Park pond recently, clearly interacting. I wasn’t sure whether it was foreplay, or jousting over control of a valuable territory.
Then one of them veered away and flew off. The other landed, and started feeding on one of the water mint not far from me.
It was a green-veined white. I’ve now seen all the four species of white butterfly which I normally see locally, although in much smaller numbers than usual – one lone individual in the case of orange tips.
