So after meeting Gary's son Ted at the Mexican border to see him off on his Pacific Crest Trail adventure, Gary and I decided to take a hike at Lake Morena, convenient and close by. I did not really expect perfect "hill top" conditions (hill-topping is the habit of some insects of congregating at a high point like the top of a hill or mountain and often establishing territories, in an attempt to intercept passing potential mates). Bot flies are known for this behavior, and amazingly, after a false alarm, in which I thought a smaller carpenter bee was a bot fly (!), we actually FOUND deer bot flies perched and periodically flying about at a high point in the chaparral overlooking the lake!
