The Alamo!

By Icy Ho (Nottinghamshire, United Kingdom)

Red ants fiercely attacking an intruder near a flower bed in a park in Hong Kong on a sunny day. Icy Ho was taking insect photos with her 90mm macro lens when she noticed this circle of red ants surrounding a black insect that had invaded their territory.
