Show me Your Hiney!

As in Hine's Emerald dragonfly! On July 13-15, I was at the Hine's Emerald Workshop that took place in St Ignace, MI. Sponsored by the US Fish & Wildlife Service, Michigan DNR, and US Forest Service, the workshop was FINALLY held in Michigan to educate state and federal and NGO conservation people on the habitats and biology of the Federally endangered species.
We visited several sites in Mackinac Co., and saw many dozens of these dragonflies. It its proper habitat Somatochlora hineana is a pretty dominant dragonfly species during the adult flight period. We observed both sexes perched, as the male is in this photo, we also saw them mating, female oviposition, male territoriality, and feedingding flights. In addition, Margi Chrisinscke found larval exuviae (a great find) at one of the sites, and we also saw larvae that were removed from crayfish burrows.
Margi Chrisisncke, Stephen Ross, Carl Freeman, and I stayed at a Little Traverse Bay Conservancy cabin on the Pigeon River E of Indian River. It was rustic and perfect for us. It meant commuting to St. Ignace every day, but that wasn't a big deal. Crossing the Mackinac Bridge at 7:30 am is a big difference from mid-day when the tourists are going across.
On Friday, Steve, Carl, and I visited several sites in the lower peninsula near Misery Bay and Thompson's Harbor. The Misery Bay area has me worried -- we saw Hine's emerald there in 2002, but there iss a lot of development going on, and most of the suspected Hine's habitat is on private land. The Thompson's Harbor sites are mostly on public lands, and cover more area.
It was a great trip for the four MOS members, and we also gathered quite a few new county records of other Odonata species.
