Timeline of entomology – 1800–1850

Entomology, the study of insects, progressed between 1800 and 1850, with the publication of important texts, definition of new orders such as Aphaniptera and Strepsiptera, and the shift to specialization.The following timeline indicates significant events in entomology in this time period.There remained entomological polyhistors – those who continued to work on the insect fauna as a whole.From the beginning of the century, however, the specialist began to predominate, harbingered by Johann Wilhelm Meigen's Nouvelle classification des mouches à deux aile (New classification of the Diptera) commenced in the first year of the century.Also then, as now, few could entirely resist the lure of groups other than their own, and this was especially true of those in small countries where they were the sole 'expert', and many famous specialists in one order also worked on others.
