📖 Overview

Adults inhabit clear, flowing creeks, usually within 20 kilometers of the sea. Commonly found in brackish waters and river mouths near mangroves, stagnant and running freshwater and coastal areas . This species has a marine larval stage, judging from its broad distribution. One of the best viewing areas is at the Freshwater creek picnic ground in Cairns, where individuals frequently aggregate along the vegetated stream margin .
