Ladybug (or Ladybird beetle)
Scientific Name: Coccinellidae (various genera and species)
Order & Family: Order: Coleoptera, Family: Coccinellidae
Size: Generally 0.8 mm to 18 mm (0.03 to 0.7 inches) depending on the species; common garden varieties are usually 4-8 mm.
Natural Habitat
Gardens, agricultural fields, meadows, forests, and other areas with abundant prey (like aphids). Many species are found on plants.
Diet & Feeding
Primarily predatory, feeding on soft-bodied insects such as aphids, scale insects, mites, and mealybugs. Some species also consume pollen, nectar, or mildew.
Behavior Patterns
Ladybugs undergo complete metamorphosis (egg, larva, pupa, adult). Adults are typically solitary but may congregate in large numbers for overwintering. They are known for their defensive strategy of reflex bleeding, releasing a foul-smelling, bitter fluid when disturbed. They are also known to feign death.
Risks & Benefits
Benefits: Highly beneficial insects, especially in agriculture and gardening, as they are natural predators of many common pest insects, reducing the need for chemical pesticides. Risks: The Harlequin ladybug (Harmonia axyridis), an invasive species in some areas, can outcompete native ladybugs and occasionally bite humans (though not harmful) or become a nuisance when overwintering indoors.
