Hi Mike, from http://www.dgsgardening.btinternet.co.uk/froghop.htm

Froghoppers are small sap-sucking insects which are able to jump great
distances if they feel threatened. The most common sighting is during
early summer as cuckoo spit on stems and leaves when the nymphs secrete
the protective froth over themselves as they feed on leaves and young
shoots. This sometimes causes distorted growth. The adults are darker in
colour and live openly on the plants, jumping away if approached.

The damage is not usually severe and they do not need treatment. There is
a risk of disease transmission if they move from plant to plant. If they
are to be removed a squirt of water usually dislodges the cuckoo spit and
the nymph. Permethrin can be used as a spray.

Hope this helps
