Note that 1e was a prepupa on the bottom of the cage, and had not spun a silk pad. When a piece of paper towel was pressed against its last larvapods, it grabbed hold. The piece of paper towel was then taped up such that the caterpillar was hanging properly. In the morning, it had pupated, but had fallen again. Bits of paper towel were attached to the stump, so it was taped up by those (the pupa felt like it was still soft). It looks like the wings expanded pretty much normally.
It was not possible to check on them on Sun. 11, 18, & 25 Aug. because the building was locked, and due to pupation, they could not be taken home for the weekend.
1e eventually emerged successfully, but its tongue was deformed and the halves did not stick together properly. Thus, this was designated as the third female for Kansas.
Subsequent to that, it was discovered that 2d, while able to feed properly, has a lame wing and cannot fly. Because of this, she is very photogenic and "put on a good show" for all the photographers.
By 22 Aug., the last day of lab class, 11 butterflies had emerged: 5 males and 6 females. Two of the females were set aside for Kansas, and 8 of the other 9 butterflies were released with press photographers watching (2d didn't fly off which is how her lame wing was discovered.). As of that time, 3 more had just emerged (1 male and 2 females--the male and female 1e were set aside for Kansas), and 6 more pupae were yet to emerge. Three of those butterflies emerged on 23 Aug, and all were females. Thus, as of 23 Aug., with 3 left to emerge, the sex ratio is 6:11. As of 26 Aug., with 1 left to emerge, the sex ratio is 6:13.
As of 27 Aug., the last adult emerged. This was the caterpillar who had been fed swamp milkweed, but was a male.
Butterfly 2d died the evening of Tues. 17 Sep. While she was given supervised opportunities to forage on butterfly bush, for the most part, she had been eating sugar water from a teaspoon, and seemed to prefer "raw" sugar or maple syrup over white sugar.
