Do caterpillars eat aphids?
Caterpillars eat aphids, but only large caterpillars. Small- to medium-sized caterpillars will eat the leaves and stems of plants but don’t have the jaw strength to tackle aphids. Large caterpillars, however, will go after aphids.
In general, the larger the caterpillar, the more likely it is to eat aphids. Smaller caterpillars usually cannot penetrate the waxy exoskeletons of aphids to suck out their insides. However, once a caterpillar gets big enough for its jaws to pierce an aphid’s exoskeleton, it can then use its sucking mouthparts to feed on it just like it feeds on any other insect prey.
Aphids are tiny insects that live on the leaves of plants. Aphids eat the parts of a leaf that contain chlorophyll and nutrients.
Do monarch caterpillars eat aphids?
The caterpillar of the monarch butterflies (Danaus plexippus) is a well-studied insect. Monarch caterpillars are voracious eaters, and like most caterpillars, they will eat almost any plant material.
And yes, monarch caterpillars feed on aphids. But milkweed is the exclusive food source for monarch caterpillars and the only plant on which monarch butterflies will lay their eggs. All milkweeds are acceptable food sources for monarchs, but some have higher concentrations of toxins than others.
The more time a monarch caterpillar spends consuming milkweed leaves, the more toxins it accumulates in its body. This makes it distasteful to predators that may try to eat them. Monarch caterpillars also have fleshy horns on their heads and behinds that are used for defense against predators.
Do green caterpillars eat aphids?
The short answer is no. Green Caterpillars are herbivores, and aphids are not plants.
Green caterpillars will eat leaves and sometimes the fruit of many different types of plants. They can be found in the garden, on trees and bushes, or in any area where there are lots of leaves for them to eat.
Do butterflies eat aphids?
Butterflies do not eat aphids. Butterflies drink nectar, which is a sugary substance produced by flowers.
Adult butterflies have a very different diet than caterpillars. Caterpillars, of course, are in the larval stage of butterflies and moths. Caterpillars have mandibles (jaws), which they use to feed on plants.
Adult butterflies have no mandibles, so they don’t eat at all. Butterflies do drink nectar from flowers using their long tubular mouthparts called proboscis. While drinking from flowers, butterflies occasionally eat pollen as well.
What are the natural enemies of aphids?
An endless amount of creatures exist that prey on aphids. These creatures include but are not limited to green and brown lacewings, lady beetles, hoverflies, midges, big-eyed bugs, damsel bugs, soldier beetles, and blister beetles. It is typically the adult and larval stages of these creatures which prey on aphids.
The larvae of lacewings are particularly effective at reducing aphid populations. They are large aphid predators which can consume up to 400 aphids in their lifetimes. Adult lacewings are also effective predators of aphids, although they do so primarily by consuming the honeydew produced by the insects rather than by eating the aphids themselves.
Aphidius colemani is a parasitic wasp that lays eggs inside living aphids. The eggs hatch inside the aphid and live off its body until eventually killing it.
The hoverfly is a dipteran with a bee-like appearance that feeds on nectar and honeydew. Its larvae are voracious predators of aphids. Both adult and larval hoverflies feed on aphids. While ladybugs (ladybirds) will eat any soft-bodied insect in their vicinity, including aphids.
Thus, Caterpillars can sometimes eat aphids for a snack. However, if the caterpillar is very small, it might not have enough jaw strength to eat aphids.
