So i was shocked when i went into my reptile room yesterday to find that almost all of my silkworms had died. I've had many silkworms in the past and have never had a mass die off like this, in fact its usually the opposite and i end up with several cocoons and very large adults. I didn't change anything in the way i keep them...I use 6qt rubber maid tubs, keep them in the reptile room which holds around 80 degrees all day, and a little colder at night, i feed the silkworm chow which i keep in a tuppeware in the fridge - with a layer of saran wrap over the chow and a lid over that. I never touch the chow with my hands, using only a clean fork to scrape it from the tub and place it in with the silkies. I had this particular batch of silkies for a couple weeks kept in this method and they were doing fine, thriving and growing. When i first noted the die off i suspected that perhaps the room had gotten unusually cold overnight, so i placed the tub with the remaining silkies over an extra piece of heat tape that is heating my cornsnakes, set at a staple 85 degrees. This morning all the remaining silkies are dead. Im a bit upset just because they are so expensive and i was going to try and breed them to save money...I also now have a bunch of silkworm chow and no silkies to eat it! ugh! I want to order more to eat the remaining chow and hopefully to grow and breed them but i want to figure out what happened. Any ideas anyone???
