Blue Tiger butterflies Tirumala hamata are one of the most beautiful found in Mt Gravatt Conservation Reserve and this has been amazing season for all butterflies as reported by ABC News – Butterflies booming in south-east Queensland

Blue Tiger butterfly caterpillars feed on only three plant species, none of which are found in the Reserve. Reference: Butterfly host plants of south-east Queensland and northern New South Wales (2013) – Moss, J. T.

Fortunately the adult Blue Tigers are less choosy, visiting the Reserve to feed on nectar of the Blackthorn Bursaria spinosa.

Imperial Hairstreak Jalmenus evagoras butterflies are breeding in the Reserve with caterpillars feeding on Early Black Wattle Acacia leiocalyx. Imperial Hairstreak caterpillar and chrysalis also depend on attendant “Kropotkin” ants – Small Meat Ant Ants Iridomyrmex sp. which provide protection in return for sugary fluids secreted by caterpillar.

Last night I learned something new about Imperial Hairstreak butterflies, they roost at night on their caterpillar food trees. At great time to get a close up photo as they slow moving in the cool night air. I was helping Helen Schwencke – Earthling Enterprises, as she collected Acacia leaves for the Hairstreak butterflies she is raising for her life-cycle research. We were both surprised to find the adult butterflies roosting on the same trees.
