The identifying difference is that viceroys have a black line across the hindwing and white dots in the black band along the edge. There are two or more generations of Viceroys per summer (depending on your/their latitude); first brood adults feed on sap flows on tree trunks, carrion, scat/droppings, and aphid honeydew, while those from later broods are more likely to chow down on nectar from a variety of flowers and on decaying fruit. Monarch caterpillars eat only milkweed foliage, and that makes them both bitter and toxic. Hello, Eric M.

Adult Viceroys are famous for being mimics of Monarch butterflies, of previous BOTW fame. So, this is what pupating looks like for a viceroy caterpillar. Monarchs are poisonous because their caterpillar host plant, milkweed, contains harmful cardiac glycosides (Batesian mimicry—the harmless imitating the harmful). Then it rolls the remaining bit of leaf into a cylinder a half-inch long and an eighth-inch wide, securing it with silk. The main visual difference between the viceroy and monarch butterfly is the black line drawn across the viceroy's hind wings, which monarch butterflies do not have. Required fields are marked *.

In human society, that would be termed an imposter. In human society, that would be termed an imposter. Admiral caterpillars overwinter in the same fashion as the Viceroy’s, are also bird-poop mimics, and are so similar to Viceroy caterpillars that only their mamas can distinguish them for sure. Donald W. Stokes, in A Guide to Observing Insect Lives, describes how the caterpillar shapes a leaf into its hibernaculum, according to pre-programmed specifications. Chronological Index to the Field Station Bulletin, wrapped in leaves of one of their food plants. Because of this, they’re more often found in wet areas like edges of lakes and rivers and moist woodlands. A black line across the hindwing distinguishes it from the Monarch. The caterpillar begins its feeding on a new leaf by chewing a notch in the midvein of the leaf, at its base. It eats the leaf from the tip down, sparing the midrib. Feeding and development resumes that following spring. First of all I know you’ve heard this a million times but I love your website, it is more encompassing than any bug identification book.

Identify butterflies and caterpillers by viewing photos. Newly-emerged stinkbug nymphs do this, too, thereby picking up bacteria—left on the shells by their mother—that will help them digest plant materials. Immature stages of the latter species are very similar to these of the viceroy. A row of white spots edge its wings. The antennae are short, spiky projections on either side of the caterpillar’s mouth. …the viceroy caterpillar is a night feeder and he uses the denuded leaf-stem for a perch during the day. The early broods live out their life cycles in a few months, forming a chrysalis when it’s time to transform into an adult. They have humps, bumps, antennae, and can bend at right angles. I may keep it and see what it turns into if you can’t. The Viceroy is apparently more noxious than the Queen. As Pyle points out in The Audubon Society Field Guide to North American Butterflies , Viceroys seek protection in each life stage by disguising themselves as something else. The viceroy is also known to rarely form natural hybrids with the red-spotted purple butterfly, scientifically known as Limenitis Astyanax. Alternately, since some parasitoids locate caterpillars by following a trail of frass, another source speculates that a ball of frass hanging in plain sight may keep them discovering the caterpillar. The BugLady found several explanations/guesses about Viceroy egg-eating behavior—to keep predators from spotting the egg/caterpillar; to harvest the protein in the egg; and to obtain nutrients that will be needed when the caterpillar matures and lays its own eggs. The hybrid species is named Limenitis Rubidus. The Viceroy’s name comes from the fact that, while it is similar to the Monarch and the Queen butterflies, it is smaller, and by extension lower in rank in the British peerage. The wing span of the adult ranges from 2 1/2 to 3 3/8 inches (6.3 to 8.6 cm). This cuts off the flow of latex to the rest of the leaf, allowing the caterpillar to then feed without difficulty. Viceroy caterpillars feed at night and hang out more-or-less in plain sight on leaf midribs during the day, and they’ve developed a curious behavior to confuse potential predators—they put together a “decoy bundle.” Let Anna Botsford Comstock, naturalist extraordinaire, explain it in an 1898 article called “Insect Domestic Economy”.

Christi Braxton 13-Nov-2008 20:42 Viceroy caterpillars have more spikes on their bumps and their tubercles on their thorax are slightly different. are trees in the willow family, especially small, shrubby species.

Caterpillars hang in a J shape to pupate. However, throughout most of … It lines the inside of the leaf with silk, and, although the leaf is still attached to the shrub, it wraps silk around the leaf stem (petiole) and secures it with a band around the twig so the leaf will not fall in autumn.

Monarchs are larger, and they tend to flap and soar, holding their wings up in a loose “V,” while Viceroys fly with faster wingbeats, and when they soar, their wings are held more horizontally. Viceroys are closely related to the Red-spotted Purple/White Admiral butterfly (Limenitis arthemis) (the Red-spotted purple and the White admiral species have been lumped and are sometimes called the “Red-spotted Admiral”). Viceroys enjoy shrubby and open fields and wet meadows throughout the U.S. (they’re less common in the Great Plains), north into Canada and south into central Mexico.
