A newly identified spider in the Ecuadorian Amazon has been generating intense interest from the scientific community. Hanging motionless beneath a leaf, it appeared to be dead, with two pale, tendril-like structures on the back of the abdomen. The strange look closely resembled a spider killed by a certain parasitic fungus. But the spider was alive ? and possibly pretending.
Herpetologist Alexander Griffin Bentley chanced upon the unusual spider during a rainforest tour in August 2025. Believing it to be a corpse overtaken by a type of parasitic fungi known as Gibellula, also called “zombie fungi” for taking control of spiders before killing them, he poked the spider and was shocked when it moved.
The species, now named Taczanowskia waska, was confirmed through detailed analysis by researchers after Bentley shared images on iNaturalist, a citizen wildlife observation platform. In the study later published in Zootaxa, authors David R. Diaz-Guevara, Alexander Griffin Bentley, and Nadine Duperre theorize that the spider’s close resemblance to a host killed by the parasitic fungus may serve one of two purposes. Either as a defensive function to deter predators, such as birds, by appearing diseased, or as an aggressive mimicry to approach prey unnoticed. Unlike web-builders, it actively hunts its food using two enlarged claws.
The finding has drawn attention from scientists, though some caution that more evidence is needed to confirm true mimicry. Others note that, if proven, it could be the first known case of an animal imitating a late-stage fungal infection. The discovery also highlights the role of citizen science, as the iNaturalist platform played a significant role in the investigation. For Bentley, the find stands out among years of exploration ? a rare and striking example of nature’s creativity.
