Recently, the use of abandoned spider webs as oviposition substrate for Chrysopidae has been reported, yet so far this behaviour had never been observed on an active (i.e. non-abandoned) spider web. In July 2020, a stalked-cluster of Chrysopidae eggs was found glued to the outermost of an active Steatoda nobilis web in Inca, Mallorca (Balearic Islands, Spain). This spider species is different from those reported so far in literature with Chrysopidae eggs on their webs. Biological implications of this understudied behaviour are discussed.
