Some photos of spring 2016's enormous butterfly migration. The caper whites do this every 6-10 years or so and come through in huge numbers after exhausting the stocks of caper creepers and bushes. The migrations seem to be wind driven and don't necessarily have any aim or progression towards other food stocks, they just explode in numbers, strip the local vegetation and migrate in such huge numbers that they can clog radiators. This one above was actually the very first one I photographed of the season in late september on an early morning walk. Natural light stack of F2.5 images at 1/60, iso500. Was super impressed with myself for getting it and had no idea there were about to be millions of them coming through. Some news articles from the time - Millions of butterflies flutter through south-east Queensland skies Caper white butterflies flock to Brisbane Millions of butterflies herald insect influx in hot and humid Queensland spring Gotta tip the guardian here for picking up on the horrible plague of black flies that came along with them also Can see some of the structural blue coming out in the black here. Big boom in crab spiders during the spring/summer too, with these white ones being the most common around here. Probably most proud of this out of all of them, image stack of natural light images at F2.5-1/160-iso200. Had to do a loooot of aligning and sorting out of 100s of images to get anything worth having out of it but it worked pretty well in the end. The weather also turned to suit butterflies (very hot - 38 degrees daytime, and high night temperatures - and humid) and combined with the caper whites taking up a lot of roosting positions, pushed other butterflies into easier to photograph territory.
