North Coast residents are being asked to look out for an extremely rare butterfly found along the coastal strip from Port Macquarie to Tweed Heads, ahead of Threatened Species Day (7 September).

The Australian Fritillary (Argynnis hyperbius inconstans) has a 6cm wingspan and is covered in orange-brown and black markings.

‘The plant often grows unobtrusively beneath grasses and other vegetation and is easiest to find during the cooler months when it is flowering.

‘One of the best ways to spot the butterfly is to look in open areas near patches of violets and other flowering plants during sunny weather, as that’s where they tend to fly.
