I have several founding colonies --3 in small formicariums and 3 still in test tubes. (For reference, the enclosures are kept with a temperature range of mid 70's to mid 80's) I've been feeding them each a bit of honey/honey water and a piece of boiled insect every week. They ants always have access to fresh water.
After about 2 days, the honey water dries up and the insect piece looks dry.
Should I be concerned that their food becomes dry? Or not, since they have access to water? Are ants interested in dry sugar/dry meat? I ask because I could imagine that the dry meat may be difficult for them to chew or cut.
Should I be giving them a refresh on their food more often?
