[...] The eggs durinthis time are developing in the paired ovaries in the bodies of the females and finally mature and are oviposited into a space formed inside the lac cell by contraction of the body of the female which is known as the incubating chamber. [...] The four lac crops are named after the Hindi months in which they are cut from the tree but it must be made clear that lac is not always left on the tree until it matures fully ; particularly in the case of the Baisalrhi crop most of the lac is cut immature leaving a certain proportion on the tree to act as brood for the next crop.
