In a surprising turn of events during an August 2025 expedition in the Amazon rainforest, scientist Alexander Bentley encountered a spider seemingly alive under a mass covered with what appeared to be a lethal parasitic fungus. Familiar with cordyceps, a fungus known for its “zombie” manipulation of hosts, Bentley was initially convinced the spider was infected. However, it was later revealed to be a new arachnid species mimicking fungus traits, as detailed in a study published in Zootaxa.
Upon noticing signs of life in the spider, Bentley sought answers on the citizen-science platform iNaturalist. Although some speculated the spider was mimicking a parasitic fungi called gibellula, further examination led to the conclusion that it was indeed a new spider species, now identified as Taczanowskia waska.
The identification process involved meticulous scrutiny of the spider’s morphology by Bentley and his colleague David Ricardo Díaz-Guevara, ultimately confirming the species as a novel discovery within the Taczanowskia genus. Monika Fischer, a mycologist from the University of British Columbia, commended the value of citizen science platforms like iNaturalist in such breakthroughs.
The spider’s uncanny resemblance to fungus raised questions about its purpose. Some theories suggest it could serve as either an aggressive hunting tactic or a defense mechanism against predators. Andrew Swafford, an associate professor of biology, noted the similarity to cordyceps stalks but emphasized the need for further research to ascertain the purpose of the spider’s appearance.
Despite the ongoing debate, Bentley expressed immense excitement over this unparalleled discovery, deeming it the most remarkable find in his rainforest explorations to date.
