• Life Cycle of Cemecidae and Reduvidae

  1. Egg laying habits of Cimex and Rhodnius

  2. egg laying in batches→Cimex

  3. egg laying in singly→Rhodnius

  4. Larvae (nymphs I) hatch from eggs

  5. 3–7 molts of nymphal instars needed to reach sexually mature stage

  6. Reduviidae develop fore- and hindwings

  7. Cimicidae remain wingless
• The eggs are laid in batches by Cimex and mostly singly by Rhodnius in the crevices of bed frames, walls, or similar household sites.
• The larvae (nymphs I) which hatch from the eggs are wingless and feed (as do all other stages) by sucking the blood of humans, and also many other mammals.
• 3–7 molts of the nymphal instars are needed to reach the sexually mature female or male stage.
• In Reduviidae typical fore- and hindwings are eventually formed, but Cimicidae remain wingless in all stages.
