Question

Mention the feeding habits and modern taking food of ladybird

Answer 1

Most people like ladybugs because they're cute, but gardeners love them for a different reason. You may be wondering, "If those tiny little ladybugs are predators, what on earth is small enough for them to hunt?" The answer to that is an aphid. Aphids are insects that suck the sap out of plants. An infestation of them can destroy whole gardens and decimate crops. A single ladybug can eat up to 5000 aphids, which means they're invaluable to farmers trying to control an aphid population. A good ladybug colony in a garden can eliminate an aphid problem in no time.
Not all ladybug species are carnivores, though. Some ladybugs also eat pollen, mildew or mushrooms. A few ladybugs, like the Mexican bean beetle, eat plants and are pests themselves. However, most ladybugs are predators and a welcome sight to gardeners. Ladybug eggs are small and yellow and are usually laid on the backside of a leaf, near aphid colonies. This ensures that young ladybug larvae will have a food source as soon as they hatch. Ladybugs also lay eggs that are infertile, or won't hatch, amongst the fertile eggs as a first meal for their offspring.
