I learned many moons ago that if you raise/rear Lepidopteta indoors and out of the Sun, you screw up their biological clock and the can emerge at any time. The world of insects is tied directly to our Sun. The promethea in question were raised indoors, but in a room with sunlight. Paul what about yours? I've raised thousands of saturnids indoors, with varying levels of exposure to sunlight, though always indirect sunlight. They all developed as expected for the region and species. Chuck I raised luna and cecropia in the same room. Natural sunlight in the room ( south exposure )+ artificial light everyday till about midnight or slightly passed. I suppose that longer exposure to light either it is sunlight or any other light can cause premature emerging. None of Cecropia was emerged as I suppose they are forced to diapause by gene as they are univoltine . Luna on the other hand might have multiple generation thru out the year and exposure to longer light may caused emerging the same year. Promethea is also double brooded so if they were exposed to longer daylight they will emerge the same year as the second generation.

I paid a visit to Hamden Orchard WA. Set out four (4) Light Traps.
I took a hike down a two track road with lot's of Joepeye Weed, Golden Rod and Purple Asters all in bloom.
I collected two Aglais milberti, (Milberts Tortoiseshell). Both males.The last time I collected a Milberts Tortoiseshell was 1973 in a large field of Clover near Mentor Headlands State Park. When I return tomorrow. I will set out some Bait Traps. The problem with my Bait Trsps? I now have all of my personal Bait Traps set out.
I just looked in my collectoin and all fourteen (14) of my specimens are males. I do not beleive that I have ever collected a female.
