Pipevine Swallowtail Eclosed after 7 weeks and 3 days

I have been keeping 13 Pipevine Swallowtail chrysalides which pupated around July 13-16. 50 Pipevine chrysalides from this time period eclosed by 29 July. The late chrysalides continue to look normal and viable. I was very surprised when 1 eclosed today. Has anyone seen Pipevine Swallowtails stay in the chrysalis this long in the middle of summer? Does anyone know why this delay happens?
