There are two types of ladybirds; predatory ladybirds and plant-eating ladybirds. Ladybirds are easily recognised by their half-circle shape, short legs and bright colours combined with black. The larvae of the predatory ladybirds are black with distinct white or yellow markings, while that of the plant eating types are yellow with black-tipped spiny projections.
Predatory ladybirds are beneficial carnivores of aphids and other small sap-sucking insects. The adults and the larvae share the same food source. Plant-eating vegetarian ladybirds can cause serious damage on a variety of plants showing a characteristic narrow banded feeding pattern. They can skeletonise leaves and cause damage to the skin of fruits like tomatoes.
