There are several members who feed human jellies to beetles. Some will say that both human and beetle jellies are just a source of sugar and moisture. The only warning I've heard, is to avoid the human jellies that have small fruit pieces in them, as they can clog a beetle's mouth parts.
Personally, I prefer to use beetle jelly for beetles, as it was made for them. There are supposed to be various vitamins and minerals in beetle jelly and human jellies may not contain the needed vitamins and minerals.
