Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.

In common with other slipper lobsters, Ibacus peronii has a broad, flattened body and a large carapace.[2] The carapace is reddish brown,[3] and reaches lengths of 2–10 centimetres (0.8–3.9 in), with the whole animal able to reach a length of 23 cm (9 in),[4] and a width of 10–14 cm (3.9–5.5 in).[3] The antennae are also long and broad, and the flattened form of the whole animal allows it to partly penetrate itself in soft substrates.[2] They have five pairs of legs and no claws. Captured animals typically weigh around 120 grams (4.2 oz), but the weight can range from 80 to 200 g (2.8 to 7.1 oz).[3]
Female Ibacus peronii grows faster and reaches larger sizes in comparison to male Ibacus peronii.[5] The size of female Ibacus peronii is significant because there is a linear relationship between the fecundity and the carapace length.[6]

Ibacus peronii is nocturnal and feeds on algae and small crustaceans.[2] They often spend the daytime buried in sand or mud.[3]

Ibacus peronii is the most commercially important species in the genus Ibacus.[3] Only wild-caught Ibacus peronii are available, although some research into aquaculture is ongoing.[3] The fishery for I. peronii is focussed around New South Wales, where it is mainly caught as bycatch of trawling for fish and prawns. There is a peak in supply in January and February, and the price is highest in areas where it is caught, because of its increased familiarity and popularity there.[3] I. peronii is almost always available at fish markets in Sydney.[4]
The flesh of I. peronii is sometimes reported as tasting of
