Hi marvin, Welcome to Project Noah! OC has a great resource you can use to help narrow down your spottings: http://nathistoc.bio.uci.edu/
When you update the ID, please consider adding your spottings to the Southern California Wildlife Mission: http://www.projectnoah.org/missions/7964554 This particular spotting can also be added to the Flies! mission: http://www.projectnoah.org/missions/8526126. Happy spotting :)
