The Speckled Line Blue can be found across northern and eastern Australia from north-eastern WA all the way south to the NSW central coast. Sydney is at the southern edge of its range, and the Speckled Line Blue is considered a great rarity in the Sydney area. Yet, I found it to be very common along a busy road in Epping in Sydney’s north. The butterflies are often seen perched on trees and shrubs or feeding from flowers.

There are a few similar species, in particular the Pale Pea Blue (Catochrysops panormus) which has a similar geographic range. The Speckled Line Blue can be distinguished from these through details in the distinctive pattern of dark patches on the underside.
