From ancient grudge break to new animosity,

Where spider blood makes spider fangs unclean.

Notes
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.

The zebra jumper’s stripes may serve as camouflage in many settings, but in this case they were no match for the excellent visual hunting abilities of a fellow salticid. (Photo: Sean McCann)

  1. Nice story. Also happy that, although not important to the narrative, neither reference was pay-walled.
