Fair enough Jacob, I wasn't trying to be rude, I did find it funny though but Im sorry.
Whoever told you that was wrong, Kenya is right at the equator and is one of the hottest countries in Africa by average outside of the Sahel region. The area where these cocoons came from does not experience those types of temperatures, pretty much ever. In Nairobi which is relatively colder, temps might get that low 2-3 times a year in a cold year, if that. Temperatures bellow 10C being unusual and only lasting for a few hours (during the night time). If you kept them in the fridge for months they are most definitely all dead. Sorry for being the carrier of bad news. For future reference, do not use the fridge ever again with Afrotropical species and please make sure you invest in some literature before you spend money with other Afrotropical species. Take your time with learning about the Miombo woodland, the Afromontane rain forest and grasslands, the dry savannas, the plants that occur there, etc.
