Ants farming aphids

Iridomyrmex ants farming herds of aphids (and their white nymphs) in Spring in Beltana. The aphids feed on the sap, in this case of an Eremophila biserrata, and excrete sugary ‘honeydew’ which is farmed by agricultural ants in exchange for protection.

Also known as ‘hole-punch clouds’, fallstreak cloud formations occur when part of a cloud of water droplets freezes into ice crystals which grow large enough to fall below as a fallstreak. Read more about fallstreak and other clouds at the Cloud Appreciation Society.
