Fierce Big-Headed Ant
A widespread tropical ant and minor invasive species with clearly dimorphic workers. Majors have disproportionately large heads used in colony defense. Colonies are aggressive and fast-growing, often dominating disturbed tropical habitats.
Did You Know?
Despite being one of the most species-rich ant genera with over 1,000 species, Pheidole remains one of the least studied.
Rhinoceros Cockroach
A large burrowing cockroach related to the giant burrowing cockroach but with a more northern distribution. It is wingless and lives in deep soil burrows. It feeds on leaf litter pulled underground.
Did You Know?
It digs permanent burrows up to a meter deep and emerges only at night to drag fallen leaves underground.
