The lower wing surface is brown to pale brownish grey with a pattern of fawn bands and spots, with the body covered in white or grey hairs. The wingspans of females are slightly larger than males, females having a wingspan of 23 mm and males 20 mm. Common grass blues have a weak, fluttering flight and so usually fly near ground level close to a food source.
Eggs are white or pale blue and have a mandarin shape with a pitted surface. Caterpillars reach about 7 mm in length, and their appearance is primarily green with a yellow stripe at the sides and a darker green stripe on the back, and brown or black head usually obscured under the thorax.

Colouration varies, ranging from pink, greyish or greenish cream and contains mottled... Wikipedia →

With luck
About 10% of wildlife watchers report a Zizina labradus sighting in Melbourne on a given day, based on 542 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November to March
In those months about 20% of wildlife watchers report a Zizina labradus in Melbourne on a given day, against under 5% in May to August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Zizina labradus sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 cities where we can rate Zizina labradus sightings, Melbourne has the highest daily chance: about 10%. Next come Auckland (New Zealand, about 10%) and Brisbane (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Zizina labradus is recorded against all the insects logged in Melbourne (542 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.
