Both are insect related mixes. I don't know exactly whats in
either of them. They are made by Sigma. The catalogue contains no
ingredients. Both are irritants.

It goes a little dry out of the fridge, but I must admit i've
never seen it go moldy

Yes, and they've also got a stinger. I work in the Biology dept,
(we do biophysics really) and I look after our fruit flies (which we
never use for anything- so they all go to my fish, or the frog groups
frogs) anyway, the manduccas are used for some nutrition thing or other,
only for 2 months each year, and their keeper was on leave, so I
volunteered (purely with fish food in mind (and overtime of course)),
and all I did was hatch eggs , feed them up, and pass them on. I had
masses spare, of all sizes, which the fish wouldn't eat. Their stingers
did fall off every now and again, but even this didn't make them more
paletable. After 2 months was up, I had loads of food left, which is why
my whiteworms got it.
