Marion, Flathead, Montana (Zone 5a) 4b - 5a ... deep in the NW rockies
this lady visited me today and left me 8 eggs on 2 different plantings of Asclepius incarnata ... and she refused to even land on the Asclepias sullivantii inbetween . It was interesting to watch her fluttering about downwind of the plants then catch the scent of the incarnata plants and fly str8 to them . I have concluded by this behavior and a couple of other trials that sullivantii is NOT on the list of preferred monarch munchies . I personally have never seen any eggs on any sullivanti plants anywhere I have found them . I tried to get newly hatched eggs from 3 different females to even sit on it for their first meal ... different leaves from 3 different plantings of sullivantii and all 3 trials they hi-tailed it off the leaves for other diggs . If anyone else has any feedback it would be appreciated ... but for now ... here at least sullivantii has been relegated to the curiosity corner of the garden . I will keep my promise to collect seed pods this fall and send them to those who asked in my A.s. thread .
