Explanation of Names
Siphanta acuta (Walker 1851)
acutus = 'sharp' (refers to the pointed wingtips); the common name refers to the leaping ability of nymphs (mature nymphs can leap as far as 60 cm)
adult wingspan ~25 mm; nymph body to 5 mm (Mau & Kessing 1993)
Adult: green and triangular, with pink eyes and pointed head; forewings have many veins and cross veins, mimicking a leaf, and cover the body like the sides of a sloping roof when the insect is at rest
Nymph: first two instars are light green, relatively flat, with waxy filaments on posterior abdominal segments, and covered with white powder or dust; later instars lose their powdery coating, develop markings of red, black, and green, and change their ground color three times; the waxy abdominal filaments are significantly reduced
established in CA(2); native to Australia, adventive elsewhere (New Zealand, Hawaii, S. Africa)
yr round in CA
Life Cycle
eggs are laid on stems or leaves in a dome-shaped masses of >100 eggs glued together and partially covered by a dark, semi-transparent cement produced by the female; eggs hatch in 10-20 days; 5 nymphal instars; adults live for ~2 months (Mau & Kessing 1993)
