Spiderlings of both sexes and adult males hunt without a bolas. This might be because the small globule these spiders could produce would dry out rapidly. Rather, they position themselves at edges of leaves and grab prey with their frontal pair of legs. Juvenile females and males of all ages of "M. hutchinsoni" have a row of strong bristles on the prolateral surface of the tibiae and metatarsi of each of their first two pairs of legs which may aid in prey capture. Females lose these bristles after a few moults. Moth flies of the genus "Psychoda" are prominent prey of juvenile and adult male "Mastophora".
