  Back in Albany, our luna moths (Actias luna) have begun to eclose, anise swallowtail (Papilio zelicaon) rearing continues, and checkerspot skipper (Pyrgus communis) larva has become a prepupa. Today, we got some exciting yet unsettling news that two lunas (Actias luna), a male and a female, have emerged back at home. When we reared these, we had put a great deal of effort into controlling the amount of daylight they received, making sure to keep them in a dark tub for at least 12 hours a day in order to increase the chances that would diapause. (Of course, the set up wasn't perfect as we were not always consistent about it and there are still many factors that might make it different that what they naturally experience that would cue diapause. For example, a diminishing photoperiod may have helped.) Even at the time, though, we had a bad feeling that not many of them cooperated, seeing as only a handful of the cocoons were the course and dark brown as they should be if they are diapausing. Because this is such an inconvenient time for them to be breeding and we would feel pretty terrible about making our mother deal with them, we decided the best thing to do for now is to get one pairing just to keep the line going and then pin the rest. As for our Papilio zelicaon, the last few are still eclosing and our mother is trying her best to hand-pair them. She reportedly already paired a male polyxenes with a female zelicaon, but it has not begun to lay yet. The several hundred pure zelicaon eggs that we already had in the cage from the mass pairings we did before we left are making progress, but according to our mother, there are only about 80 or so caterpillars. Mysterious losses always seem to be high when rearing outdoors, even with a screen cage to protect them. . . She also found eight random caterpillars on a different fennel in our yard that we must have overlooked when we were there.  Authors

Timeline 2017–present
Ithaca, New York This timeline is a series of daily posts recording our observations and experiences with various insects around the Cornell University campus in Ithaca, New York, starting from the time we moved here in 2017. As this is a personal blog, we try to keep collections for our entomology course work to a minimum, and mainly focus on just the species we catch and raise for our own fun and interest. Posts prior to this time can be viewed at Timeline 2012-2017: Albany, California. Archives (80)
