Kojiro Shiraiwa author of The Butterflies of San Diego County addressed the DHOSA members at their year end meeting (Saturday, December 17, 2016) to give a summary and orientation of ways to collect butterfly data to be collected throughout 2017. The species list generated would be compared to other years of butterfly presence or absence. In particular the list will be compared to the historical 1967 survey of Hilltopping Butterflies done by Oakley Shields.
