About Brachysaura minor

Hardwicke's Bloodsucker (Brachysaura minor)

Hardwicke's bloodsucker, scientifically known as Calotes minor, is a small, stocky agamid lizard native to South Asia. This species is recognized by its pot-bellied appearance, short tail, and a distinct coloration pattern of olive-brown with dark-brown, light-edged spots on its back and tail. It also features unique markings on its neck and head, with an ink-blue interior to its mouth.

Distribution and Habitat

Calotes minor is found across parts of Bangladesh, India, and Pakistan. It primarily inhabits terrestrial environments, though it can occasionally be found in trees. Its preferred habitats include fragmented dry forests, arid regions, barren deserts, and desolate areas, often situated within the Indo-Gangetic plains.

Behavior and Diet

This lizard is diurnal and crepuscular, meaning it is active during both the day and twilight hours. It typically shelters in burrows dug near the roots of thorny bushes. While often observed resting on stones, it is capable of climbing shrubby vegetation. Hardwicke's bloodsucker is known for its sluggish movements and docile nature, rarely attempting to escape when approached.

Its diet is predominantly insectivorous, consisting of grasshoppers, earwigs, beetles, bugs, arthropods, and spiders. In some instances, it has also been noted to consume flowers.

Reproduction and Physical Characteristics

Calotes minor reproduces oviparously, laying its eggs between April and June. Females deposit four to six hard-shelled white eggs in burrows. Females are generally larger than males and exhibit more vibrant coloration during the breeding season. Adult lengths commonly measure around 10 cm, with a maximum recorded length of 18 cm (snout to vent: 6 cm).

Conservation and Human Interaction

Despite a baseless reputation for being harmful, Hardwicke's bloodsucker is entirely non-venomous and harmless to humans. Its role in the ecosystem involves controlling insect populations. However, this unfounded reputation has unfortunately contributed to its depletion. The species name 'minor' is a Latin word signifying 'less' or 'smaller,' reflecting its diminutive size within the agamid family.
