Spicebussh butterflies do very well indoors and are easy to farm. The white markings on the abdomens of these instars resemble the uric acid deposits in bird and lizard droppings making the resemblance even more striking. Barb was watering them a few days later when she noticed some leaf damage. Spicebush Swallowtail Butterflies By Jeff Ormiston flying north from Mexico this spring, it was obvious that this would be a banner year for the various swallowtail butterflies native to our parks and natural areas. The caterpillars also have special disguises just in case they get seen: the early instars are bird-dropping mimics, like many other swallowtail species. 1995. Garden City, NJ. Photograph by Donald W. Hall, Entomology and Nematology Department, University of Florida. I was so confused to keep finding very very different images of the Spicebush Swallowtail caterpillar- thanks for this great post detailing each of the instars and the differences between them! Because the name Papilio is still so widely used in sources available to the public, it will be used here instead of Pterourus for practical reasons. Deering MD, Haslitt T, Scriber JM.

Reports (e.g., Howe 1975, Robinson et al. The spicebush swallowtail is threatened throughout its range due to mortality of its caterpillar host plants from laurel wilt fungus (Raffaelea lauricola T.C. Although spicebush swallowtails employ extensive mimicry throughout their lifecycles, mimicking bird droppings and green snakes as caterpillars, and mimicking the poisonous pipevine swallowtail (Battus philenor) as adults, they suffer from extensive predation. 633 pp. The caterpillar stage is for 16 to 20 days. This feature is not available right now. This is its camouflage to help defend itself from predators. Eggs should hatch with in one week.

Howe WH. As a caterpillar grows it molts and the different stages between each molt are called instars. Nitao JK, Ayres MP, Lederhouse RC, Scriber JM. Pupation is usually near the ground on slender stems among leaves (West and Hazel 1996). However, Cinnamomum camphora is classified as invasive by the University of Florida’s Institute of Food and Agricultural Sciences, and planting is not recommended. Princeton, New Jersey. Borror DJ. These “prepupae” retain the yellow color during the pupation process (Figure 17). Sassafras growing in more open habitats tends to more pubescent. 2005, Gatrelle 2000, Warren et al. Their eyespots are much bigger, with the black part being kind of shiny. To maximize butterfly populations in yards, both caterpillar hosts and nectar plants for adults should be planted. (Compiled from a variety of sources). Note bulging “pupils” of false eyespots. Scott JA. They do this four or five times, and each new skin is called an ‘instar.’.

The coloration of both caterpillars and adult butterflies works to warn away vertebrate predators. In the early stages (instars), Spicebush Swallowtail caterpillars resemble a bird dropping. The leaf shelters constructed by developing larvae likely provide some protection for all larval instars. One of the most beautiful and interesting of these is the Spicebush Swallowtail Butterfly, Papilio troilus troilus.

The following species are documented hosts: Silk bay (Persea humilis Nash) and the relatively rare pond spice, (Litsea aestivalis [L.] Fernald) are also probably hosts in Florida (Minno and Minno 1999). First instar larvae chew a slit or slits (near the tips of leaves) from the leaf edges toward the midribs and spin silk across the leaves. The prepupae wander off the host plants to pupate. Pupae from larvae developing under long photoperiods may be either green (Figure 9) or brown (Figure 10). However, larvae can be tolerated on large dooryard citrus trees in order to enjoy the soon-to-develop magnificent adult butterfly stage. Stanford University Press.

There are at least three generations in the Deep South (Gulf of Mexico area and peninsular Florida) with peak numbers of adults in late spring and early fall in central Florida and two generations northward (Cech and Tudor 2005, Howe 1975). Before pupation, full-grown larvae cease feeding and turn to a yellow color. (1991) reported that neonate Papilio troilus starved to death rather than initiating feeding on non-lauraceous hosts (including sweetbay, Magnolia virginiana L.; tuliptree, Liriodendron tulipifera L.; and common pricklyash, Zanthoxylum americanum Mill.). He described a new subspecies fakahatcheensis from southwestern Florida, and stated that specimens from the area of middle and upper-southern Florida are intermediates of Papilio troilus troilus and Papilio troilus fakahatcheensis.

But in the transition to fifth instar, the caterpillar changes dramatically to a beautiful lime green color, with eye spots and a black band. Minno and Minno (1999) have extensive lists of both native and exotic nectar plants for butterflies. Pupal color dimorphism in swallowtail butterflies – timing of the sensitive period and environmental control. In addition to the generalist predators that prey on Lepidoptera larvae, there are at least two tachinid flies (Compsilura concinnata [Meigen] and Lespesia frenchii [Williston]) (Arnaud 1978, p. 659) and one ichneumonid wasp (Trogus pennator [Fabricius]) (Krombein et al.

In a study, it was found that those spicebush swallowtails that normally feed on redbay did not grow as well on spicebush or sassafras during the first instar of development, while all insects studied grew better throughout the larval period on sassafras or spicebush. These different stages between molts are called instars. A male spicebush swallowtail was featured on the third butterfly stamp (issued January, 2013) in the U.S. Figure 12. Papilio troilus.
