Western Spotted Orbweaver

Fascinating facts about the Western Spotted Orbweaver

• Western spotted orbweavers span an astonishing stretch of the New World, from the western United States down through Mexico and Central America to at least Costa Rica, then popping up as isolated reports in Colombia, Venezuela, Ecuador, Peru and even the remote Galápagos Islands.
• The name Neoscona oaxacensis carries a history of scientific reshuffling: Eugen Keyserling first described the spider in 1863 as Epeira oaxacensis, linking it to Oaxaca, Mexico. Just a year later, Eugène Simon split the broad genus Epeira, creating Neoscona in 1864. Finally, F.O. Pickard-Cambridge reassigned the species to Neoscona in 1904, a classification that endures today despite occasional Galápagos-specific synonyms.
• Females of Neoscona oaxacensis can grow up to 18 mm long, about the length of a small paperclip, while males top out at just 13 mm. The biggest individuals come from the Galápagos, where specimens are among the largest found.
• The spider's dorsal abdomen sports a bold black-and-white pattern. South American individuals differ: their abdomens are more slender and display a clearer light central band with a wavy border, compared with the broader North American form.
• When examined from behind, a female's epigyne stretches 2.5 times longer than it is wide. Mature males, by contrast, develop a modified terminal palp ending in an S-shaped conductor.
