Adults and larvae of this gorgeous insect eat leaves of milkweeds. BugFan Mike ID’d a number of the DLLs pictured in the episode; the DLL reclining with its belly on the leaf is an alien DLL, Chronological Index to the Field Station Bulletin, Tettigoniidae, Two (Family Tettigoniidae). Insect-eating birds don’t know this, however, and the beetles successfully deter predation through their coloration. As for the insect in the photo, that’s the “milkweed bug,” also known as Oncopeltus fasciatus. (Look it up).

The milkweed leaf beetle (Labidomera clivicollis) is a species of beetle from the family Chrysomelidae. Leaf Damage: MONARCH FEEDING. The adult Swamp Milkweed Leaf Beetle stayed within one ten-stalk milkweed colony for at least the last three days of June, wandering from--and dining upon--one flower head after another. As adults they feed on the leaves, buds, and flowers. When feeding on milkweeds, they start by clipping the side veins off the leaves, draining the sticky, toxic sap that is the plant's defense against herbivores. Chrysochus cobaltinus, the cobalt milkweed beetle or blue milkweed beetle, is a member of the diverse family leaf beetles (Chrysomelidae). They are not harmed by the toxin, but predators that feed on them are (a few tropical birds and rodents are able to eat Monarchs without harm—Mother Nature is always stirring the pot).

The red milkweed beetle, known scientifically as the Tetraopes tetrophthalmus, lives primarily in the eastern United States and Canada. Labidomera can diapause only in the adult stage. In fact it is the only host plant for monarch butterflies. Milkweed Leaf Beetle larvae and adults do not absorb the cardiac glycosides in milkweed like a Monarch, so they have no toxic compounds in them and will not poison a predator. In the lab, increasing day lengths induce breeding, shortening day lengths induces diapause. There are 12 to 15 variously-marked species of beetles in the genus Tetraopes, the Milkweed Longhorns, north of the Rio Grande, but only three of those are Eastern. 1985. We had an outbreak earlier. Larvae and adults cut several side-veins of a milkweed leaf prior to feeding, to reduce the sticky latex that would otherwise be produced at their feeding sites.

The swamp milkweed leaf beetle (Labidomera clivicollis) is found on the various milkweeds it eats, often in grassy areas or on roadsides. Even though they can consume milkweed sap without harm, SMLBs, like Dogbane Leaf Beetles of previous BOTW fame, have devised a way not to consume quite so much of it. Life history consequences of body size variation in the milkweed leaf beetle, Labidomera clivicollis (Coleoptera: Chrysomelidae). One researcher suggested that SMLBs picked Swamp Milkweed because it often grows surrounded by water, which discourages predators from the ground—a beetle with a moat. In Central Texas, this beetle is active in the spring and fall due the the host plant growth as determined by the bimodal pattern of annual rainfall in the region . We're guessing thanks to the voracious appetites of it and numerous SMLB instars our Swamp Milkweed blossoms will be fewer again this year at Hilton Pond Center . Negative. Milkweed Bug Control. Swamp Milkweed Leaf Beetles can be found in marshes, bogs, swamps, and other wet habitats. Picking off the competition?

Part of the orange and black milkweed mimicry complex, which includes Monarch Butterfly, Red Milkweed Beetle, milkweed bugs, and an assassin bug. Its rubbery sap contains cardiac glycosides that, at the very least, make its imbibers throw up—unless they have, like the other milkweed grazers and a variety of herbivores that successfully feed on toxic plants, developed an adaptation that allows them to deal with the chemicals. Except that a male with a hefty mite load is more likely to try to interrupt a mating pair. The voyeuristic DLLs may have been attracted by courtship pheromones. They do well in more developed areas, too, like backyards, roadsides, and parks that grow milkweed. This article discusses some fascinating facts about milkweed you probably didn't know, and the plant's unique relationship to many insects. In long associations, only 10% of takeover attempts by other males are successful. P.S. Ms. SMLB mates promiscuously and for long durations.

Phenology and dormancy in the milkweed leaf beetle, Labidomera clivicollis (Kirby). Interestingly, about 15% of SMLB eggs are infertile, and these are commonly cannibalized (trophic egg-laying), which suggests that Mom puts out these infertile eggs to protect the fertile ones (but the BugLady’s not sure you can call it cannibalism if no one was home in the first place). Photo by: James Morgan. How do they survive the “not-so-camouflaged” part? Adults overwinter in leaf litter and orange tubular eggs are laid on the underside of milkweed leaves in the spring. Both larval and adult female SMLBs dabble in egg cannibalism (males abstain). It belongs in the huge Leaf Beetle family Chrysomelidae (more than 1,700 species north of Mexico), many of whom are named after the plants they specialize on. As in many longhorn beetles, the antennae are situated very near the eye–in the red milkweed beetle, this adaptation has been carried to an extreme: the antennal base actually bisects the eye. The male who stays with her longest has the best chance of having his sperm outnumber/overwhelm the opposition’s from another mating. Male DLLs, unlike spiders, have a penis, and they mate face-to-face. Larger females lay more eggs, heavier eggs, and more successful eggs.

Multiple eggs are laid under milkweed leaves; multiple larvae (grubs, to beetle fanciers) hatch out (more about that later) and feed together on milkweed leaves for a while before going their separate ways. This plant is decorated for Halloween all year long. Male SMLBs may produce more than 250,000 sperm; about 30,000 may be transferred during a 24 hour mating, and “mating associations” may last up to five days. Milkweed plants have flowers that attract butterflies, bees, and other pollinators. ... 4th instar larvae will chew out a circular area in milkweed leaves, this helps reduce the amount of sticky sap that flows as the larva feeds: ...
