Ptilocnemus lemur is a species of feather-legged bug in the family Reduviidae native to Australia. Commonly known as the feather-legged assassin bug, it is a predator with a specialized gland called a trichome that it uses to attract and paralyse ants before feeding on them.

It has a small head with a pair of feathery antennae with three segments, and a large down-curving proboscis, a wide thorax and a moderately broad abdomen. The wings have three veins. The hind pair of legs are much larger than the other two pairs and the tibiae of these are heavily clad with bristles. The head and thorax are yellowish-brown and the abdomen mottled grey and black.
Ptilocnemus lemur is native to Australia where it lives in forests. It can be found on the trunks of trees where its drab colours help to camouflage it as it stands on the bark. The trichome is a glandular structure on the ventral surface of the third abdominal segment. It produces a secretion that is attractive to ants and which paralyses them. In addition to this, there are glandular patches on the front few abdominal segments, and these... Wikipedia →

Rare
Under 5% of wildlife watchers report a Ptilocnemus lemur sighting in Brisbane on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 856th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Ptilocnemus lemur in Brisbane on a given day, against under 5% in September to July, the lowest months. That is one of Brisbane's driest months, with about 45 mm of rain against 160 mm in February.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Ptilocnemus lemur sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ptilocnemus lemur is recorded against all the insects logged in Brisbane (11 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.
