Common Froghopper – Philaenus spumarius:  A variable species, with many dramatically different colour forms (brown being the most common).  Usually found on vegetation such as bushes in grassy areas from June to September.  The larvae are the familiar producers of ‘ Cuckoo-spit’ so often seen in gardens. In fact, this is actually the nymphs which live live in a protective frothy mass of bubbles.  The adult is a champion jumper and is able to leap 70cm into the air (a greater feat than the flea and similar to a human jumping over a tower block!  Adults mate back-to-back and the subsequent nymphs go through a number of stages.  Both adults and nymphs feed on plant sap using specialist, sucking mouthparts known as a rostrum, which contains two pairs of stylets (slender probes).  The outer pair have serrated edges for piercing.  The inner form a kind of canal for food to pass up and saliva to pass down.  The tip of the rostrum has receptive cells to access the suitability of food.
