The 14-spotted ladybird is a small beetle very common in the European habitats. It feeds mostly on aphids that preys voraciously both at larval stage than as adult. Contrarily to other larges size species Propylaea visits plants even when aphid colonies are still at low density, acting as biocontrol agent already at low infestation density. Then when colonies become more numerous it promptly reacts reproducing till building conspicuous populations. Its flexible behaviour makes this predator apt to preventive introductions in protected crops like sweet pepper, aubergine, melon, cucumber and others where the damage threshold related to aphid does’t allow curative introductions of other predators.
