Siphanta acuta is a species of planthopper in the family Flatidae; this species is native to Australia, but is now found in various other parts of the world. About 10 mm long, they resemble small leaves and are generally found in trees. Its common names are the green planthopper or leaf bug (in Australia and New Zealand), and the torpedo bug (in Hawaii).
Adult Siphanta acuta are large-winged (as are other members of the family Flatidae) and bright green. Their wings are triangular, sharply pointed at the tip, and sit held like a steep roof. Their wings project behind the end of their abdomen and almost reach the ground. Most of their body is concealed. A pointed head and distal segments of front and middle legs (sometimes tarsus of hind legs) are visible.
The body length of mature green planthoppers is around 9.3 mm. They have two pairs of wings, three pairs of legs, one pair of antennae, and compound eyes on either side of their head. They have piercing/sucking mouthparts and females have an ovipositor at the end of the abdomen.
Nymphs of Siphanta acuta are white with a pair of waxy filaments either side of the sixth abdominal segment, with two long tufts at the... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Torpedo Bug is recorded against all the insects logged in Los Angeles (296 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
