Drinking Swallowtail
I shot this video of a Tiger Swallowtail drinking from a stream, but I can't figure out why it's excreting the water as fast as it drinks it?!
Does anyone at BG know why it's doing that?

Note: While on YouTube set the video quality to 1080P, and watch the video full screen for the best detail!

Australian Faunal Directory
[cite:476418]
a rich and reliable source of up-to-date information on taxa known to occur in Australia, including general info on great many higher taxa (~9,000 families), most of which also occur in our area.
The easiest way to get to the page you need: http://www.environment.gov.au/biodiversity/abrs/online-resources/fauna/afd/taxa/xxxx -- replace 'xxxx' with the name of the target taxon, case-insensitive (say, 'psocoptera' or 'tephritidae')
