Three small horns project from the head and thorax. ![]() The chrysalis is either green or brown, and is more compact compared to chrysalids in the genus Papilio. The larva has a yellow, foul-smelling, forked gland called an osmeterium which it will use to deter predators, especially spiders and ants. In both forms, between the swollen thorax and the abdomen, there is a yellow, black, and bluish-white band. The more common form is green with yellow and white transverse stripes the rarer form is black and banded with white and orange. Young caterpillars are black with lighter colored transverse stripes. The round egg is pale green, later turning orange brown. Since the caterpillars are cannibalistic, females lay their eggs singly on pawpaw leaves or on the tree trunks. Other food sources include rotting fruit and urine. These nutrients aid the male in reproduction. Males participate in a behavior known as puddling, in which individuals congregate on sand, gravel, or moist soil to obtain salts and amino acids. Both males and females avidly visit flowers, including species from the families Apocynaceae, Brassicaceae, Fabaceae, Lythraceae, Polemoniaceae, and Rosaceae. Females will fly slowly when searching for suitable host plants. They usually fly 0.5 to 1.8 meters (2 to 6 ft) above the ground. Males will patrol near host plants in search of females, flying swiftly and directly. It has two broods in the north and three to four in the south, with the first brood being the most numerous. The zebra swallowtail can be seen from late March to August in the northern portion of its range and from February to December in the southern portion. Summer forms are larger, have broader black stripes, and longer, black tails with white edges. Spring forms are smaller, more white, and have short, black tails with white tips. marcellus has two seasonal forms, one occurring in the spring and the other in the summer. A red stripe runs along the middle of the ventral hindwing. The inner margin of the hindwing has two blue spots on the corner and a red spot near the body. A pair of swordlike tails extend from the hindwings. The triangular wings are white to greenish white with black longitudinal stripes.

Not sure why you would want or need one.maybe you live on a busy street or if you own a restaurant it could protect your outdoor dining area. When I did a Google search for bollards, I discovered you buy one for yourself. Although, there was actually a lawsuit a few years ago when one became loose and rolled into someone's car in a Target parking lot. ![]() I kind of figured they were made of concrete because if you've ever tried to push one of them (like I have) you can't. But, in Target's case, they're used to stop vehicles from running right through the front 's a scary thought. Mental Floss says bollards are mostly found on the water's edge to give boaters something to tie their boat to. The Red Balls at Target are Called BollardsÄid you know there is a real name for these red balls? I've seen them referred to as spheres in different articles, but, they're actually called bollards.
