If your citrus looks like it is getting munched on, make sure you look for Swallowtail caterpillars before you grab your insecticides. Giant Swallowtail butterflies lay their eggs on lemons, limes and even grapefruit trees this time of year, and the caterpillars literally look like bird poop (as their camouflage). So if you see moving bird poop on your citrus, just leave them be and they’ll be beautiful Swallowtails in no time!
