A New Malagasy Spider with Matjaž Gregorič

On an expedition to Madagascar, Matjaž Gregorič and his research team came upon a damaged termite nest that had a few other invertebrate visitors. When they experimentally damaged the nest again, they found two unexpected things: spiders ballooning in to prey on the termites as they rebuilt, and hopeful ants standing by to steal termites from those spiders. It created what the authors called “a perilous Malagasy triad”, a three-way predator-prey-kleptoparasite interaction that tells a very interesting story about chemical signaling and arthropod behavior. As a bonus, they identified the spider involved as a brand new genus and species, named Vigdisia praesidens to honor Vigdís Finnbogadóttir, Iceland’s first female president. Listen in as researcher Matjaž Gregorič gives us the full story, as well as his thoughts on why it’s important to pursue science for science’s sake.

Matjaž Gregorič’s paper “A perilous Malagasy triad: a spider (Vigdisia praesidens, gen. and sp. nov.) and an ant compete for termite food” is in the July 14th issue of New Zealand Journal of Zoology.
