As spring is approaching, I notice again the appearance of “cuckoo spit” on some of our plants (in particular the leaves of a ngaio bush). The frothy lather is the work of the nymphs of froghoppers. Several years ago I decided to have a closer look, using reversed lenses. In this picture we look onto a nymph (a few millimetres long) and the bubbles it created around itself (to retain moisture and to protect against predators). In the last picture one sees the proboscis, used to extract copious quantities of sap from the leaf below; the sap is then pumped out at the other end in the form of bubbles. Fascinating to watch if you make time for it.
