Theclinesthes serpentata, commonly known as the saltbush blue or chequered blue, is a species of butterfly in the family Lycaenidae that is native to Australia. The species was first described in 1869 by German entomologist and physician G. A. W. Herrich-Schäffer. It is common throughout all Australian states and territories, and can be found in a wide range of habitats.
This is a very small butterfly, with a wingspan of 18 mm (0.71 in) for both male and female specimens. On the top side, the wings have broad margins of brown, with blue colouration towards the thorax. The underside is brown with patches of white. Male and female specimens have the same colouration, which ranges from mid to dark brown and purple-blue to blue. The larvae grow to 9mm in length, with a textured skin surface and colouration ranging from pale green to grey-green. The caterpillars blend in with their host plant, the saltbush, but have black and yellow stripes lining their back that can distinguish them.
The saltbush blue has a wide distribution, due to their preferential food plant being dispersed across biomes and states. Thus, the butterfly occupies a diverse range of habitats... Wikipedia →

With luck
About 10% of wildlife watchers report a Saltbush Blue sighting in Grampians National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026.

GBIF citizen-science records
It is estimated from how often the Saltbush Blue is recorded against all the insects logged in Grampians National Park (5 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.
