1/22/2022      CHANGED INTO A VIRTUAL MEETING!! Annual Membership Meeting with guest speaker Ken Osborne: Biology of the endangered Quino Checkerspot and its purported response to climate change in California.

Join the Central Arizona Butterfly Association (CAzBA) VIRTUALLY (via ZOOM) Saturday, Jan 22nd, from 2 pm to 4 pm for a presentation by Ken Osborne. For the past 25 years Osborne has conducted butterfly ecological/biological research, undertaken comprehensive arthropod inventories and diversity studies, and implemented species reintroduction, habitat restoration, mitigation, and conservation plans for a wide range of threatened, endangered and sensitive butterfly species. Today's presentation is titled: "Biology of the endangered Quino Checkerspot and its purported response to climate change in California". The checkerspot butterflies (Euphydryas, pictured) are a charismatic group with many species across the northern temperate latitudes both old world and new. One species is the iconic Edith’s Checkerspot (E. editha) with many geographic subspecies over western North America. This presentation will focus on the biology, ecology, and complex population dynamics of southern California’s Quino Checkerspot (E. editha quino) as the backdrop for a saga of historic decline, endangered status, and conservation. With these concepts in hand, Ken will make a critical examination of two landmark studies of climate-change induced species range shifts for 1) a purported northward latitudinal shift for the species as a whole, and 2) a purported elevational range shift for populations in southern California. You are invited to watch this presentation via Zoom. When: Jan 22, 2022 02:00 PM Arizona Register in advance for this meeting: https://asu.zoom.us/meeting/register/tZwocuyrqzkjEtLHvCz0FtMxX21OLouqE8-S After registering, you will receive a confirmation email containing information about joining the meeting.

10/28/2021      Review results 2021 Butterfly Counts in Central Arizona and COVID guidelines

We are looking forward to our meeting tomorrow night and hearing about the amazing results of the recent butterfly counts in Central Arizona. However, please be advised that because of the state of COVID in Arizona, we will encourage participants to take precautions against COVID. Right now, transmission rate is rated as HIGH in Maricopa County and as a result it is recommended that all participants in indoor meetings be masked (https://www.cdc.gov/TemplatePackage/contrib/widgets/covidcountycheck/) Hence, we will encourage everyone to put on a mask as they enter the building and keep it on except while eating and drinking. Also, individuals who are feeling ill or who suspect they may recently have been exposed to COVID are asked not to attend the meeting. We appreciate your help in keeping this meeting safe for all participants. At this meeting of the Central Arizona Butterfly Association led by our president, Ron Rutowski, we will review the results of the three butterfly counts that were done in Central Arizona in 2021. The results will be compared to previous years and we will explore the causes of year-to-year in the number of species and individuals recorded. There will be plenty of time for questions. You may even bring some identification challenges on a memory stick if you'd like. This will provide an opportunity for us to learn from each other, while taste testing Laura's savory homemade cookies and lemonade. read more »
