As many of you know, Julie Craves and I are writing the Michigan Odonata Atlas. This year, we hope to accomplish quite a bit of the framework. However, there are still some gaps in the distributional data that would be nice to have filled. You can see where we have a dearth of records in certain counties by examining the excel spreadsheet available on the MOA Downloads page. I hope to have a bunch of files available soon that list species records for each county.
Last year, Doug McWhirter added a lot of records for Eaton co., and Jeff Sommer has really added a lot of new species for Saginaw County over the past two seasons. I’d like to especially note that Rhyne Rutherford collected a UP record for Libellula incesta in Dickinson Co. He and Bob Marr have both contributed some nice western UP additions. With this year’s early warming and mild winter, it will be interesting to see what kind of phenology patterns we get. Our first Anax junius was recorded in MI on March 18. That is almost a month earlier than typical. Of course, we have cooled off since then, but degree-days are cumulative, so pond species ought to be emerging earlier than normal very soon.
Here are the links for the resources:

Let me know if you need glassine envelopes for the 2012 season. I have a bunch in, and will gladly mail them to you. I know some of you keep field notes, and here is a good source for field notebooks. Julie and I look forward to your continued assistance, and let’s hope that 2012 is a banner year. Best wishes, Mark
