Always the Spider and the Fly, but not this Time!

We have described a new record of spider egg-predating fly of the family Sarcophagidae in Chile. These flies hover around spider webs and lay their larvae directly on the spider egg sac. With numerous species of these flies found worldwide, we conducted a thorough review of their biology and predation habits. Although the larvae have a predatory behavior, we discuss that adult females display a behavior similar to that of parasitoid flies, treating the spider egg sac as a host. This behavioral pattern offers insights into the evolutionary dynamics of predation and parasitism across various Sarcophagidae lineages. You can check more on the link below.
