People have been warned not to touch a strange foam-like substance that is set to start appearing in gardens as the warm weather sets in. The period from the end of May to the end of June is peak season for an insect which leaves an odd 'spittle' on garden plants.
Some have said it looks like a ball of froth, or foam, but householders have been urged by experts not to try and clean it off their plants. The substance is made by an insect known as a spittlebug.
The insect coats itself in a ball of foam for protection as it sucks on the sap from a plant for nutrition. The red and black creature's offspring, also known as froghoppers, then hatch on a plant which has the leftover ball of foam, Yorkshire Live reports.
