About Hyllus semicupreus (Simon, 1885)
This jumping spider species follows the common size pattern for spiders: females are significantly larger than males. Females have a total body length of 8–9 mm (0.31–0.35 in), while males measure 7–8 mm (0.28–0.31 in) in length. These are heavy-bodied jumping spiders, commonly found among foliage and inside tree trunks. They build thick, oval silken webs on the undersides of leaves, including the leaf spikes of coconut trees. The silk sac is empty during daytime. At night, the male typically occupies the sac, though females may sometimes inhabit it as well.
