Helpis minitabunda

Unlike most spiders, males are larger than females; males can grow up to 10 mm in body length, whereas mature females may be up to 8 mm long.

H. mintabunda, like other Saticidae (and most Arachnids), exhibit sexual dimorphism, both physically and behaviourally: in particular, the front pair of legs are characteristically longer and darker in colour in males than in females, and the male's head – or "caput" – is noticeably flat-topped and covered in creamy white hairs, which continue onto the upper surface of their large and more prominent chelicerae – a feature unique to males.

Males are more active and aggressive hunters, noted for their speed and agility, often preying on smaller spiders, while females are more cryptic.^[3]

The pre-mating courtship dance between males and females of the species has been observed to last between two and three hours.^[4]

H. mintabunda are commonly observed in the East and Southeastern regions of Australia, while they are listed as an invasive species in New Zealand.^[3]
