As noted in Chapter 2, considerable difficulty has arisen in deciding whether endopterygote orders are monophyletic or polyphyletic. Five orders, Mecoptera, Trichoptera, Lepidoptera, Diptera, and Siphonaptera, show clear affinities which enab

Not only does it provide physical protection for internal organs but, because of its rigidity, it serves as a skeleton to which muscles can be attached. It also reduces water loss to a very low level in most Insecta, a fe

The adjustments they make may be immediate and obvious, for example, flight from predators, or longer-term, for example, entry into diapause to avoid impending adverse con­ditions. The nature of the response depends, obviously, on the natur

Of the six, the order Hymenoptera appears most isolated phylogenetically and is sometimes considered in a distinct superorder, the Hymenopteroidea. The other orders are then united in the Neuropteroidea.
