The Canadian Tiger Swallowtail is smaller than the Eastern or Western Tiger Swallowtail, but otherwise similar in appearance. The males are often seen puddling on wet soil using their proboscis to suck up salts and minerals that are not available from flower nectar. Since this has only been observed in males, it is thought that these nutrients are passed on to the females during the mating process.
