Buy insect cocoons:  Click here are three major layers viz., vitelline membrane, the endochorion and the third (Mo), which further radiates down into the micropylar canal. Fresh food plant (replace often) and hygiëne (remove droppings) and a not too high density (they can generally stand being crowded, but overcrowding will result in viruses, bacteria and pathogens wiping them all out, so be mindful of how many you keep together. Caterpillars do not sequester toxins from their poisonous food plants and are thus safe to use as feeder animals; they do however have a crop that stores food for 1-2 days (as a defense mechanism they may “vomit up” their crop/gut content, that may be toxic due to them feeding on  toxic plants such as Ricinus communis) so it is best to not feed them for two days prior to feeding so their gut is clean. The surface of the egg chorion of eri moth, revealed the structural elements viz., the micropylar rosette surrounding the micropyle, micropylar canals, shell imprints, aeropyles and the regional differentiation at the different poles.
