What's the difference? Galleria reproduces explosively, taking a long time to get going, then producing a very large number of 3-4 cm long larvae. Achroia grows faster initially but more steadily, with larvae and adult moths present in the culture at most stages, producing steady supply of 2-3 cm long larvae - more useful for dendrobatid keepers:
Both types of waxmoth can be cultured on a medium consisting of approximately:
- 3 parts wheatbran
- 3 parts wheatgerm
- 3 parts ReadyBrek
- 1 part dried yeast
- Enough honey and glycerin (=glycerol) to produce a dry, crumbly mixture (*not* sticky).
Add lots of crumpled up paper towels to the culture for pupation. Cultures need lots of ventilation or you get condensation and they go moldy. I use plastic food storage containers the lids of which have a section removed and replaced by metal gauze glued in place with silicone adhesive, or better, melted into the lid with a soldering iron. Whatever culture vessel you use, bear in mind that the larvae have an amazing ability to chew through almost anything that is not made of either glass or metal.
When first set up, the culture appears to stand still. The original moths, however, will have laid thousands of eggs, and the larvae which hatch from these are extremely tiny, remaining well hidden for a few weeks. Then, suddenly, they seem to appear from nowhere and chomp through the food at an alarming pace. At the same time they generate a tremendous amount of heat, and the base of the culture will be distinctly warm. Not only that, but water produced from respiration will condense on the inside of the lid and sides of the container, even if it is well ventilated. This can cause the medium to become rather too wet and soggy if there is insufficient ventilation.
To feed, just pick the larvae out of the medium and offer them to your animals.
