Chrysoperla pallida

(formerly Cc2 slow-motorboat)  The range of this species covers most parts of temperate western Europe, notably Switzerland and northern Italy westward across most of France at least to central Spain, northward into the British Isles, eastward to Hungary, and southeastward into Greece. It is usually found in shrubs and trees at the edges of fields, or even in open woodlands.  Shown below is one SRU of the length typical of solo songs, consisting of many short volleys.  Songs exchanged during duets tend to be shorter — 8-16 volleys — but are otherwise very similar to the song illustrated.  The ‘spiky’ appearance in the oscillograph is due to the insect actually striking the substrate with its abdomen at the start and/or end of each volley.
