By day 14, only two were left. Pupation is rare on green surfaces. But the caterpillars are immune and gratefully accept the toxicity as they feed. Two pipevine swallowtail caterpillars eat the leaves of a toxic plant in the pipeline family. Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis.It has been studied for its evolution of mimicry, and for the several stable hybrid wing patterns within this nominal species; it is one of the most dramatic examples of hybridization between non-mimetic and mimetic populations. Your Poisonous Pipevine Swallowtail stock images are ready. All the host plants that the pipevine swallowtail larvae eat have something in common: they contain a toxin that is harmful or distasteful to many animals but not to the pipevine swallowtail  larvae! Gainesville, FL: Scientific, 1994. This is called Batesian mimicry. In 1777, it was moved to the genus Battus by Scopoli. [4] Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. Prior to emerging as an adult, the wing markings of the butterfly can be seen through the chrysalis. Tyler, Hamilton A., Keith S. Brown, and Kent H. Wilson. The toxins in the plant make the butterflies poisonous to birds and other predators. They are found in many different habitats, but are most commonly found in forests.

Pupation begins when the larva releases silk to form a support structure so that the chrysalis can hang safely. However, tropical pipevine plants are too toxic for pipevine swallowtails. It is also known as the blue swallowtail (e.g., Howe 1988, Iftner et al. The Pipevine Swallowtail (Battus philenor) is black with a single row of pale spots near wing edges.This beautiful butterfly is sometimes called the "Blue Swallowtail".The male has iridescent blue hind wings, and the female a lighter blue coloring. “Predation By Anolis Lizards On Battus Philenor Raises Questions About Butterfly Mimicry Systems.” Journal of the Lepidopterists’ Society 41.3 (1987): 141-44. High levels of acid make the larvae and adults unpalatable to bird predation. The pipevine swallowtail butterfly uses this and related species as its larval host plant. The bright orange spots present on larvae and adult butterflies are thought to serve as warnings to predators, alerting them to the potential bad taste, should the predator decide to make a meal out of the swallowtail. Aristolochic acid presence may also act as an oviposition chemical stimulant. It contains the lethal toxin aristolochic acid. They are about 6 to 7 cm in length. You can watch the whole cycle at https://www.youtube.com/watch?v=u2cE86AA1q0. The larvae feed and wander for several weeks before finding an isolated spot to pupate. The caterpillar incorporates this toxin into its body to use as a defense against predators. [12] A distinctive feature of these eggs which is shared by all Aristolochia butterflies is that the outer layer of the egg is covered by a firm and nourishing excretion laid in vertical stripes along the outside. Unfortunately, there is one predator that isn’t affected by the toxins—the green. [9][16], "Is Your Pipevine Plant Swallowtail-safe? Print. The pipeline swallowtail mainly consumes the leaves of the toxic plants Aristolochia, also known as the pipevine or birthwort. Even the eggs have the toxin! Florida Butterfly Caterpillars and Their Host Plants. Its life cycle was beautifully illustrated during the 18th century by John Abbot (Smith 1797) (Figure 1). The caterpillars of the Pipevine Swallowtail feed on the poisonous host plant, Aristolochia, also known as the pipevine, Dutchman's pipe or birthwort. Larvae filaments help them identify vertical plants, which are then determined to be host or non-host by using their mouthparts. Full grown larvae have a glossy or velvet appearance due to many fine hairs. The males’ iridescent hind wings are also believed to be involved in attracting females. The iridescent black-and-blue pipevine swallowtail (Battus philenor) uses various species of pipevines as host plants for its eggs. Swallowtail Butterflies of the Americas: A Study in Biological Dynamics, Ecological Diversity, Biosystematics, and Conservation. Battus philenor, the pipevine swallowtail or blue swallowtail, is a swallowtail butterfly found in North America and Central America. Birds and other animals know not to eat these butterflies.

For more science news sign up for our eNewsletter. Several other swallowtails subspecies have similar coloring to the pipevine swallowtail so that predators may also associate them with distaste. In areas of higher temperature such as Texas and Arizona, a red coloring dominates. A common host plant is the Virginia snakeroot, (Aristolochia serpentaria), which can be found in the Eastern United States and in Florida. These butterflies frequent thistle (Cirsium) flowers, the pink and purple flowers of the Phlox species, and ironweed of Vernonia species. Stanford: Stanford UP, 1986.
