Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.

Leaves, stems, and green unripe fruit of the tomato plant also contain small amounts of the poisonous alkaloid tomatine, [36] although levels are generally too small to be dangerous. [36] [37] Ripe tomatoes do not contain any detectable tomatine. [36] Tomato plants can be toxic to dogs if they eat large amounts of the fruit or chew the plant ...
Although they appear to be furry and soft, the caterpillars actually have a defense system of poisonous bristles that can break off into your skin if they are touched.
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 ...
Because gregaria caterpillars have darker coloration and maintain positions higher up on the crops, they have increased exposure to the sun, resulting in more rapid development than solitaria caterpillars. [1] Generally, African armyworms are not noticed by farmers until the caterpillars are ten days old and start exhibiting the gregaria phase ...
Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. They are known for sequestering acids from the plants they feed on in order to defend themselves from predators by being poisonous when consumed. The adults feed on the nectar of a variety of flowers. Some species of Aristolochia are toxic to the ...
