Birds are ladybugs’ main predators, but they also fall victim to frogs, wasps, spiders and dragonflies. Ladybirds lay their eggs in clusters or rows on the underside of a leaf, usually where aphids have gathered. Larvae, which vary in shape and colour depending on the species, emerge in ...
The relative impact of cannibalism and predation on the development and survival of fourth instar larvae was assessed in two species of aphidophagous ladybird beetles, Coccinella septempunctata and Harmonia axyridis . The effect of eating aphids, conspecific larvae or heterospecific larvae on larval ...

Neonate larvae of E. connexa required eating prey daily to develop into adults. However, non-prey food such as honey water solution did prolong larval and adult survival but neither fulfilled larval development nor adult reproduction. Honey water solution promoted 100% adult survival up to 25 ...

Where predation of larvae is recorded, it can be higher than that of ladybird adults [38], suggesting that much predation of ladybirds (i.e., the soft-bodied larvae) may be missed in dietary inventories. When the species or genera of ladybirds are recorded, they are usually the large ...
