A variant sub-species of energy spider was discovered by Han Solo and Leia Organa Solo while investigating a series of ground quakes on behalf of Lando Calrissian, owner of the spice mining operation. The newly discovered subspecies had a reddish hue and lacked the hooks and spines that are present on the arms of typical spiders. These "red spiders" were found to be herbivorous, feeding on the giant fungi found in the lower reaches of Kessel's spice mines. These red spiders had a poisonous effect on baseline energy spiders, allowing the two to coexist. Genetically, the two different types could even mate, though no documentation of the act nor results existed.
