Remarks

The easiest method of differentiating the two main types of bugs is by looking at the location of the eyes. Moreton Bay bugs have their eyes set towards the edge of the head, while Balmain bugs have them set toward the middle of the head. The Moreton Bay bug is also a little thinner in the body than the Balmain bug. Females have a pore on the inside base of each third leg, males do not.

Note: Cooking Ideas identified by dark bold text are relevant to this species

The meat of bugs, found only in the tail, has a medium-to-strong flavour. They can be bought as frozen meat or whole, to be eaten on their own as an entrČe, or as part of a main dish.

They are best prepared by poaching, steaming, barbecuing or grilling. As bugs provide good presentation and marry well with other seafood, they are excellent for cold seafood platters served with a light lemon mayonnaise, aioli or dill vinaigrette.

When cut down the centre lengthways, bugs will grill and barbecue beautifully over a high heat. They are superb served on their own, with the above-mentioned dressings or pesto, or as a warm salad with fresh asparagus and parmesan. To prevent discolouration of the flesh, sprinkle with a little lemon or lime.

The flesh of the bug is an ideal, flavoursome filling for meats, such as an alternative in carpetbag steak or with veal, asparagus and hollandaise (the veal oscar). Bug meat is also an appetising additive to fish cakes served with sweet chilli coriander.

Suggested Wines

A cold seafood platter of saltwater species, including bugs, demands a racy, dry and crisp wine to refresh the palate. Try a leaner style of young semillon sauvignon blanc blend.
