Most insects can't digest this strong sap, but a few can, including this one and the world-famous monarch butterfly, which feeds on milkweed and nothing else. This striking caterpillar lives in groups on milkweed plants and drops to the ground when it feels threatened....
Certain insects, including monarch butterfly caterpillars, are immune to the toxin. By feeding almost exclusively on milkweed leaves, they are able to accumulate enough of the poison in their bodies to make them distasteful to predators which means that milkweed is agreat plant for butterflies. ...
However, a Cornell study found that the corn killed or damaged monarch butterfly larvae that feed on corn pollen-covered milkweed. 4: Soy Even if you don't drink soy milk, you could be ingesting soy through foods like chocolate. Juan Silva/Getty Images Of all crops, soy is the ...
The common milkweed is found pretty much everywhere in North America east of the Rocky Mts., except for the driest plains, which we may be on our way to joining considering recent weather trends. Having said that, at the time of writing this we have had a couple weeks of seriously hot ...
The Ornate Checkered Beetle (Trichodes ornatus) is only found in North America. The larvae live in bee nests and are parasitic. The larvae feed on bee larvae and pollen. Adults feed on milkweed, yarrow, and other plants that are yellow. Adult females grow to fifteen millimeters with males...
They feed on woolly aphids, small insects that infest alders and other trees, and as a result of this high-protein diet, grow very quickly. Like most other Lycaenidae caterpillars, they are slug-like and inconspicuous; however, the pupa resembles the head of a snake, a form of protective ...
(vegetative biomass:H2 = 0.12). We found significant and relatively high heritability estimates for herbivory after flowering (H2 = 0.588) and milkweed stem weevil damage (H2 = 0.418) when measured on a presence/absence basis, but not quantitatively when measured as percent leaf ...

We found the first direct empirical evidence for two previously hypothesized defense synergies in milkweed (latex by secondary metabolites, latex by trichomes) and identified numerous other potential synergies and antagonisms. Our strongest evidence for a defense synergy was between leaf mass per ...
