Big-headed ant

Pheidole megacephala

A species of Big-headed ants, Also known as African big-headed ant

There are two types of worker ant, the major or soldier ant and the minor worker. The common name of bigheaded ant derives from the soldier's disproportionately large head. This has large mandibles which may be used to crush seeds. The soldiers are about 4 mm in length, twice as long as the minor workers. The colour of both types varies from yellowish-brown or reddish-brown to nearly black. The rear half of the head is smooth and glossy and the front half sculptured. The twelve-segmented antennae are curved and have club-like tips. The waist or petiole is two-segmented with the node immediately behind conspicuously swollen. There are a pair of short, upward-facing spines on the waist. The body has sparse, long hairs.

Habitat Preferences of Big-headed ant Through Different Life Stages
The eggs of big-headed ant are typically found in the protected environment of the nest's nursery chambers, where temperature and humidity are carefully regulated by worker ants. Larvae also develop within these chambers, with workers providing food and care. Once they pupate, the pupae remain in the nest until they mature into adults. To find these stages, one would search for nests, often located in the soil, under stones, or in dead wood, in warm regions. Adult big-headed ant can be found foraging on the ground, in leaf litter, or on plants, for food to bring back to the colony.

Are Big-headed ant harmful to humans?

Different kinds of ants cause different troubles to humans. To be sure, compared with other dangerous creatures, common ants are very harmful to humans, and most of them just gather in the courtyard or room to disturb human life.
But there are some dangerous groups. They have strong jaws and sting needles and can bite or sting when under stress. Usually, ants only cause physical damage and the pain caused by formic acid. These discomforts do not even need to be dealt with, and can be recovered quickly. But there are still very few ant stings that can cause allergies and even death. Other ants can pollute the environment, destroy buildings, affect harvests and even spread diseases.

Bite Humans

Big-headed ant is not characteristic for biting humans. If disturbed, it could defensively bite, but this is atypical. Bites, although rare, could cause mild irritation due to their method of biting and injecting formic acid as a defense mechanism. Typically, big-headed ant would rather retreat than engage with humans, so bites are incidental, not habitual.

Structural Pests

At both adult and larval stages, big-headed ant compromises the integrity of houses and can chew through electrical wiring, posing fire hazards. Infestations often lead to food contamination. Their presence ranges from mild annoyance to severe structural damage, depending on infestation size.
