This Monarch caterpillar, hanging around today in the gardens of TWWIAGE, is enjoying a nice snack of milkweed. In fact, this caterpillar will have to do more than just nibble on this leaf, it will have to consume a huge amount of milkweed in order to bulk up its body mass prior to pupation. During the two weeks the caterpillar takes to go through five instars of growth it can increase its original body weight up to 2000 times. Apparently, a Monarch caterpillar can chomp through one milkweed leaf in under 4 minutes. That's a lot of milkweed. And a lot of frass, or caterpillar poop to the layperson. (Ha! I just typed the word poop. Titter, titter.) I love nature.
