According the Royal Horticultural Society, cuckoo spit is the white frothy liquid secreted by the immature nymphs of a sap-sucking insect known as a froghopper or spittlebug. I bet you all knew that already but ignoramus that I am, it’s all news to me! (I knew it was cuckoo spit, obviously, but wasn’t sure what it actually was). It appears in late spring when the call of cuckoos can be heard, but otherwise has no connection with the bird. So that’s the scientific bit over and done with but if you would like to read more, click here. Sherkin Island thistles have suddenly caught my eye, and I have been amazed to see how many different and beautiful varieties there are on the island. I’m hoping to come back at a later stage with another post on the subject.
