The hover fly is an innocent little fly, and with the advent of warm weather, there are a number of them about doing what they do: pollinate flowers. Not all creatures view them so benignly.
A few hover flies were pollinating daisies.
But, one of those flowers contained a crab spider. Bye-bye hover fly.
…and that is why we have to watch out for`crabby people too…they can spoil your day..
