Two spiders, both alike in family,
In fair Victoria, where we lay our scene,
From ancient grudge break to new animosity,
Where spider blood makes spider fangs unclean.
Jumping spiders (like all spiders) are generally predators of insects and other arthropods. Spiders are the second most common prey items of Phidippus johnsoni (27% of their diet, just after dipterans, coming in at 30% of the total count), and comprise 5% of the diet of Salticus scenicus.
