My tiny caterpillars have been growing quickly. I have had to rehome them in bigger containers. Here are some of the caterpillars in each of the three batches four days ago. They are all still looking very similar to each other.
Anyway here are the caterpillars now, what a difference in just a few days. The darkest ones are the ones that are the high-yielding silk variety (blancos), but they probably won't be dark for much longer, as these are quite pale when they are big.
Above are the zebras, and this time the 5p coin is with the "green" caterpillars. There is quite a variation in the sizes of the little caterpillars, just a couple of days' difference in the hatching time is making a big difference in their current size.
