The Common black ant, garden ant, Lasius niger
Appearance

• Workers 4 to 5mm long.
• Queens 15mm long.
• Dark brown/black in colour.
• 1 small segment at waist point (pedicel).
• No sting present.

Lifecycle

• Queens overwinter in soil. Eggs are laid in late spring. Larvae hatch 3–4 weeks later.
• Larvae feed on secretions from the queen's salivary glands until the first worker ants emerge.
• Worker ants continue with larval care, nest building and food foraging.
• Fertile males are produced later in the season.

Habits

• Foraging worker ants follow well–defined trails around food sources. Sweet foods are preferred   but high protein foods will also be taken.
• Swarming characteristics – mating between queens and fertile males takes place on the wing   mid to late summer. Males perish after mating.
• Nest locations – often outdoors in soil and below paving slabs on the sunny side of buildings.
