9/5-6 tagged & released ~70 butterflies. Reared on tropical, common & swamp milkweed & collected as late instars or chrysalis.
The number of larvae in milkweed plants has notably decreased, as has the incident of NPV, due in part to near complete defoliation of the plants. (9/1-9/6 NPV = ~12/d).
Mortality in rearing cages = ~12/d from parasitic flies and NPV.
Tagging will shift to netting wild butterflies when #200 has been released.
