Does temperature affect pupal development?

[dannus plex]

Maybe this question has been answered previously, but does air temperature affect pupal development? I raised a cat late last summer and into the autumn which stayed in pupa for 14 days in an area which air temperatures dropped to 60 degrees or lower. I have recently raised several cats which were in pupa for 8 days or less in temperatures of 80 degrees and higher.
Any comments?

In my experience, the later in the season the longer it can take for the entire cycle to be completed. I don't know if it's temp or daylight. The days are getting shorter, but the temps are also getting cooler, so it may be a combination of both. I have also found that some of the last butterflys to hatch can also be smaller than normal.

The hotter it is the faster the cycle goes. The cooler, it gets slower. A friend once had a pupa that took 6 weeks to emerge.
