After hatching, the larvae will begin eating, including the other eggs in their clutch. [7] Certain species lay extra infertile trophic eggs with the fertile eggs, providing a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. [41]
Coccinella septempunctata, the common ladybug, the seven-spot ladybird (or, in North America, seven-spotted ladybug or "C-7" [1]), is a carnivorous beetle native to the Old World and is the most common ladybird in Europe.

Ladybugs aren't just cute little insects. They play a large role in our ecosystem. Here's what they eat and why you might want them in your yard.
Female H. convergens can lay over 1000 eggs over the span of a few months during the spring or early summer. [3] In some populations, the beetles may undergo diapause if there are limited food resources to delay reproduction. [4] H. convergens eat soft-bodied insects, with aphids being the primary food resource. [2]

Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
Curculio glandium eggs are deposited in acorns by the adult weevil chewing channels into the fruit. The eggs are then released using an ovipositor, a long, narrow organ featured in female weevils. [2] These do not reach the acorn's embryo and are healed by the plant, sealing the holes and protecting the eggs from parasites.
