While strolling today in the University Parks I discovered that flies do not think it is beneath their dignity to sip a little nectar, when they get a chance. I am not sure what benefit they give to the plant in return.
Here’s a series of pictures taken today. The bumble bees are very skilled at negotiating these prickly flowers.
A better lens would be needed for better quality, but I am no photographer, nor son of a photographer.
