Virus-specific small interfering RNAs (siRNAs) are a central component of antiviral responses in insects. In this issue of Cell Host & Microbe, Poirier et al. (2018) demonstrate that virus-infected flies and mosquitoes produce virus-derived extrachromosomal circular DNAs that serve as a template for the biogenesis of antiviral siRNAs.
