The life cycle of a thrip is unique and fast. Eggs are laid on plant tissue and hatching young will immediately begin to feed on any part of the plant which presents sap and vital fluids containing nutrition. After a week or so, these larva will have passed through two stages having eaten all the time. Once the third stage begins eating will stop and at this stage some may even develop wings, fly off or simply crawl down into leaf litter and mulch to pupate. It is probably the hatching of the pupa which are most responsible for the cases involving biting thrips. The fourth stage, the pupa, is where they turn into fully mature adults ready to mate and reproduce. Females have the unique ability to lay eggs which will prosper whether they mated with a male or not. In general, eggs produced from fertile females will yield offspring of either sex; eggs generated by females which could not find males will produce nothing but males. This biased result insures the local population gets a good balance for the future since thrips develop so quickly. This whole process from egg to adult can happen in as little as two weeks depending on the species and the local environment. For this reason it is important to realize just how quickly a few can turn into a few thousand and further explains why it is all important to head off these developing colonies and populations when first found.
