Laboratory rearing, description of pre-imaginal stages, and ontogenesis of four species of Latridiidae (Coleoptera). Abstract. Four species of Latridiidae were reared in the laboratory and all the ontogenetic stages were obtained for Latridius hirtus, L. consimilis, L. minutus and Enicmus rugosus. The mature larvae of these four species are illustrated in detail. The duration of development from egg to imago lasted 17 days (L. consimilis, E. rugosus) up to 23 days (L. minutus). The complete life cycle (from egg to egg) lasted 22 days (E.) up to 32 days (L. consimilis). The oviposition rate was 1–3 eggs per day. Egg deposition varied between 20 eggs (L. consimilis) and 40 eggs (E. rugosus). 69 detailed figures are provided.
