What combination of body sections and legs defines the Subphylum Hexapoda placement for *Operophtera brumata*?

Answer

Three main body sections (head, thorax, abdomen) and three pairs of legs

The classification of the Winter Moth into the Subphylum Hexapoda serves as a crucial sorting step within the larger Phylum Arthropoda, definitively placing it among the true insects. The term 'Hexapoda' literally means 'six feet.' This classification mandates that the organism possesses a body clearly divided into three primary tagmata or sections: the head, the thorax, and the abdomen. Furthermore, it must possess exactly three pairs of legs, totaling six legs, all attached to the thoracic region. This characteristic immediately separates *O. brumata* from other arthropods like myriapods (which have many legs) or crustaceans (which often have different body segmentation and appendages).
