Caterpillar foraging Woolly Bear. This species is a generalist feeder, consuming many plant species, including herbs and trees. [1] Based on the caterpillars' wide range of food plants, this moth could be found almost anywhere that plants grow. [8]
Plants contain toxins which protect them from herbivores, but some caterpillars have evolved countermeasures which enable them to eat the leaves of such toxic plants. In addition to being unaffected by the poison, the caterpillars sequester it in their body, making them highly toxic to predators. The chemicals are also carried on into the adult ...
Yellow bear on milkweed.. It has a diet of a wide range of low-growing plants, including ground cover like grass and clover. The larvae are defoliators, skeletonizing the leaves they feed on, but only the late summer batch of caterpillars is plentiful enough to do much damage to crops.
As caterpillars, they tend to feed on a wide range of host plants. This includes oak, apple, birch, willow, hackberry, cherry and coniferous trees such as fir and spruce.
In early instars, the larvae feed together in groups, but beginning in the third or fourth instar the caterpillars begin to feed individually. [8] [9] The larvae eat the entire leaf blade and are capable of consuming a few leaves each. Thus, large populations of greenstriped mapleworms are capable of defoliating trees.
The caterpillars eat from several host plants. [6] Caterpillars begin as yellow with black stripes, but become blue green over time. Once they are blue green, they develop four red and one yellow protuberances. These caterpillars go through several instars or skin shedding, and usually after the fifth shedding the caterpillar is ready to form a ...
As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. [3] With a wide geographic range throughout Central and North America, H. lineata is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. [4] [5]
