The Crusader Bug is a member of the Squash bug family (Coreidae).
Crusader Bugs are typically quite large bugs with long oval bodies that can produce a strong smell as a deterrent to predators. They are easy to recognise by their yellow cross mark on their backs.
Crusader Bugs live in urban areas, agricultural areas, coastal heath, forests and woodlands.
Crusader Bugs are found throughout Australia, as well as Indonesia and the Indo-Pacific.
Feeding and diet
Crusader bugs feed on a wide range of plants, including wattles, sennas and eucalypts and orchard plants (such as citrus) and garden plants (such as roses). Crusader Bugs prefer new shoots and pierce plants with their sucking mouthparts.
Crusader bugs are considered to be minor pests of citrus and wattles. On a good note, they are considered to provide biological control of the noxious weed Mimosa pigra.
