Summary
Anthocoridae, or minute pirate bugs, are small predatory insects that are beneficial in controlling pest populations. They inhabit a variety of environments and are characterized by their small size, distinct body shape, and feeding habits that focus on soft-bodied arthropods.
Physical Characteristics
Anthocoridae are 1.5–5 mm long and have soft, elongated oval, flat bodies, often patterned in black and white. They have an extended head, and the antennae are longer than the head, visible from above. The species possess a three-segmented beak or labium for feeding, two ocelli as adults, and two pairs of wings including hemelytra and membranous hindwings.
Identification Tips
Anthocoridae can be differentiated from common plant bugs (Miridae) by their two ocelli as adults and their specific body shape. Additionally, their size ranges from 1.5 to 5 mm and their distinctive black and white patterns can help in identification.
Habitat
Anthocoridae inhabit various environments including cryptic habitats like galls and are also common in open surface environments such as agricultural crops.
Distribution
Anthocoridae are found worldwide, with the highest diversity in the tropics and Holarctic Region.
Diet
They primarily feed on other small soft-bodied arthropods, but they can also consume plant material.
Life Cycle
Eggs are laid in plant material, hatching in approximately 3 to 5 days. Nymphs go through five instars, taking at least 20 days to mature into adults, which typically have a lifespan of about 35 days.
Reproduction
Eggs are deposited in plant material, and the development involves nymph stages before reaching adulthood.
Ecosystem Role
Many species act as beneficial biological control agents, preying on pest species such as the eggs of the corn earworm (Helicoverpa zea).
Economic Impact
Anthocoridae are significant in agriculture as biological control agents, aiding in the management of pest populations.
Health Concerns
Some species can inflict minor bites leading to swelling and irritation, but do not feed on human blood or inject venom.
Collecting Methods
- Sweep netting
- Hand collecting from plants
Preservation Methods
- Pinning
- Ethanol preservation

Misconceptions
It is a common misconception that minute pirate bugs feed on human blood; however, they do not feed on humans and only cause minor irritation when biting.
