Herpetogramma licarsisalis, commonly known as the grass webworm or pale sod-webworm, is a species of moth in the family Crambidae. It is distributed in most of the Old World tropics, including South Africa, Zimbabwe, the Democratic Republic of the Congo, Togo, Sierra Leone, Sudan, Ethiopia, Egypt, Réunion, Madagascar, Saudi Arabia, the United Arab Emirates, Hong Kong, Malaysia, Borneo, the Philippines, New Caledonia, Australia, and New Zealand. It is an introduced species in many other parts of the world, including Hawaii, continental Spain and the Canary Islands, Portugal, Great Britain, Turkey, Cyprus, India and Sri Lanka.
The flat, elliptical eggs are deposited singly or in masses on the leaf blade's upper surface along the midrib. The caterpillars hatch after 4-6 days and undergo five instars in the following 14 days. First instar larvae are characterised by a black head capsule, whereas later instars have a brown head capsule. Mature larvae are green to brown, sometimes with a rose tint. Full-grown larvae are about 20 mm long. Pupation occurs in a loosely-woven hibernaculum and takes about 7.3 days. After eclosion from the pupa, the... Wikipedia →

With luck
About 10% of wildlife watchers report a Grass Webworm Moth sighting in Blue Mountains National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 93rd most-seen of the 789 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Grass Webworm Moth is recorded against all the insects logged in Blue Mountains National Park (34 verified sightings from 2019 to 2026), 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.
