Short summary
We re-evaluate a recently published observation of a spider preying on a bat which made the news internationally and highlighted the potential negative impact of the spider. Spiders are not well loved creatures and often fall victim to false or exaggerated claims in the media. In the current case, we believe the authors' lack of familiarity with bat biology led them to an erroneous conclusion of predation, which was echoed by the media, when no evidence was shown to support this.
