The document classifies the class Insecta into 31 orders, with 4 orders belonging to the subclass Apterygota which includes wingless insects, and 27 orders belonging to the subclass Pterygota which is further divided into exopterygota and endopterygota based on wing development. The orders are also grouped according to their wing flexing mechanism into paleoptera, orthopteroid, hemipteroid, and panorpoid complexes. The lecture provides details on the characteristics and examples of the different orders within the class Insecta.

?The class Insecta has two subclasses viz., Apterygota and Pterygota. Apterygota Pterygota Primarily wingless evolved from wingless ancestors. Winged or secondarily wingless evolved from winged ancestors e.g. Flea, head louse, bed bug. Metamorphosis is totally absent or slight. Present Mandibular articulation in head is monocondylic i.e. single Dicondylic i.e., double. Pleural sulcus in thorax is absent. Present. Pregenital abdominal appendages present. Absent.
The subclass Apterygota has 4 orders namely 1. Thysanura - Silverfish (Thysan-fringed, Ura-tail) 2. Collembola- Springtail or snowflea (coll-glue; embol-peg) 3. Protura - Proturans or Telsontail (Pro-first, Ura-tail) 4. Diplura - Diplurans or Japygids (Di-two; Ura-tail) ?The sub class Pterygota has two divisions, namely exopterygota and endopterygota based on the wing development. Character Exopterygota Endopterygota Wing development External Internal Metamorphosis (Hemimetabola) Incomplete (Holometabola) or gradual (Paurametabola) Complete Pupal stage Absent Present Immature stage Naiad or Nymph Larva No. of orders 10 17
