Hunting
Every spider species produces the pheromone of only one specific moth species (or a small set) and is thus dependent on it. However, bola spiders will try and often succeed to catch any insect that is flying nearby, aided by their good eyesight. They also seem to detect prey by the sound of their approaching flight.
Spiderlings and adult males hunt without a bola. 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. Moth flies of the genus Psychoda are prominent prey in juvenile and adult male Mastophora. Adult spiders consume the bola after at most half an hour if the hunt was fruitless.
Female Mastophora catch an average of two moths per night, but as many as six or seven catches during a single night have been observed.

Famous quotes containing the word hunting:
“The man that once did sell the lion’s skin
While the beast lived, was killed with hunting him.”
—William Shakespeare (1564–1616)
“The French manner of hunting is gentlemanlike; ours is only for bumpkins and bodies. The poor beasts here are pursued and run down by much greater beasts than themselves; and the true British fox-hunter is most undoubtedly a species appropriated and peculiar to this country, which no other part of the globe produces.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“God prosper long our noble king,
Our liffes and saftyes all!
A woefull hunting once there did
In Chevy Chase befall.”
—Unknown. Chevy Chase (l. 1–4)
