Are there large numbers of iNaturalist observations found globally or does it appear to be rare?What is the native range of this species? Is it native or introduced to to southern California?What is the conservation status of this species? If it is native to Southern California, is it a species of conservation concern? Why or why not? If it is introduced, how/why was it introduced and what makes the species successful outside of its native habitat?
Note: Be sure to include a picture or screenshot of a worldwide map of observations from iNaturalist as evidence.  Phenology (timing of important events in the life cycle)  for your species For each response, you should have an in-text citation (author, year) for the source of the information.
