Cryptolaemus montrouzieri, common name mealybug ladybird or mealybug destroyer, is a species of ladybird beetle native to eastern Australia. The beetle feeds on mealybugs and other scale insects, and is used to control those pests on citrus orchards worldwide.
Étienne Mulsant described C. montrouzieri, naming the new species after a Marist brother and missionary, Abbe Montrouzier, who wrote an "Insect Fauna of Woodlark Island". Cryptolaemus montrouzieri is endemic to Queensland and New South Wales, Australia. It is now also present in Europe (France, Italy, Spain, Greece, Cyprus and as far as Northern Germany), in North Africa, in the Afrotropical realm, in the Nearctic realm, and in the Neotropical realm.
Cryptolaemus montrouzieri can reach a length of about 6 millimetres (0.24 in). Adults of this species have the typical ladybird shape but, unlike many of the often brightly coloured Coccinellidae, the elytra of these small ladybirds are predominantly dark brown and have no spots. Head, antennae, pronotum, the end of the elytra and the legs are orange-brown. Larvae can reach a length of 14–15 millimetres (0.55–0.59 in). They show... Wikipedia →

Under 5% of wildlife watchers report a Mealybug Destroyer sighting in Austin on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 900th most-seen of the 1624 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mealybug Destroyer in Austin on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Mealybug Destroyer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Mealybug Destroyer is recorded against all the insects logged in Austin (18 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.
