Urban environments are not usually considered to be rich in biodiversity; surveys of urban biodiversity often report limited and declining numbers of species. Hartop et al. show that they can nevertheless yield surprises, at least when it comes to insect diversity. Studying thousands of samples from private backyards in Los Angeles, CA, the authors have discovered 30 previously unknown species of Megaselia flies. Possible reasons for this unexpected diversity may be the wide range of geography in the Los Angeles area and the introduction of invasive species via its large container ports. It remains unclear, however, whether this diversity represents native or invasive species.
