I got my very first beetle on the 10th May and I just found my very first baby worm
I just skimmed the surface with a teaspoon and spread it out on a sheet of white paper under a light with magnifying glass I could see them. I put this one on a $2 coin to show size. I am in Australia and its winter here not that it gets very cold in north Queensland.
So you should be getting babies very soon if you dont already have them. They are tiny.
Well, I tried the white paper technique... I took a little of the substrate and spread it on a white paper. I don't have a magnifying glass so I just used the flashlight on my cell phone. I looked, and looked, and looked and I found... nothing. Ha, just kidding, I found my first baby worm!!!
