Adult midges spend the day in shady spots such as between the buttress roots of large trees, in crevices in logs, in hollow stumps or in piles of husk debris.

They emerge at variable times of day to swarm near their hiding locations, and disperse in the late afternoons and early mornings.

The females lay batches of up to about ninety eggs on damp piles of plant debris.

The adults survive for about a week and there are thought to be about twelve generations of the midge per year.

Successful pollination requires the deposition of at least 35 suitable pollen grains on the receptive parts of the flower, and is dependent on the season.
