Chelepteryx collesi By Matt Young February 9, 2015 12:00 MST Photograph by Jim Foley. Chelepteryx collesi – white-stemmed gum moth, Canberra, Australia. Mr. Foley writes, “The caterpillar is about 12 cm long! Yet another member of the Australian fauna you don’t want to mess with. … We seem to have more venomous stuff than most places: lots of snakes, stonefish, spiders, jellyfish, blue-ringed octopus, etc., not to mention the crocodiles and sharks.”
