Studies on Morphological Variation in the Ladybird Beetles (Coleoptera: Coccinellidae) Abdominal Segments in Ventral View | Chapter 12 | Cutting-edge Research in Agricultural Sciences Vol. 7

 The current research focuses on Ladybird Beetle Morphological Variation (Coleoptera: Coccinellidae). The abdomen of a Coccinellidae consists of 1st to 8th or 1st to 9th segments, with the 1st, 2nd, and 3rd segments being visible. The ladybird beetle's abdomen only shows the 4th to 8th ventral segments in males and 4th to 9th segments in females. The abdomen of coccinellids plays an important role in oviposition and predator mimicry. Their parts are more chitinized and flexibly attached to one another, with the last two carrying tarsi or hair. Each species' first abdominal segment has been extensively studied and found to be substantially different. Abdominal form, scale, and colour are all important morphological characteristics in different Coccinellid species. Abdominal form, size, colour, and hairs can vary seasonally in their behavioural activity for finding odours or honeydew in their host plant for complete reproduction. The study found that different Coccinellidae species have their own distinct shape and scale, which is their morphological characteristic. At the same time, various species characters play a major role in their abdominal colour variation.
