What is the fundamental body shape shared by most aphids, including yellow varieties?

Answer

Pear shape

Aphids, regardless of their specific coloration or species variation, share a basic, fundamental body plan structure. They are classified as small, soft-bodied insects whose general contour is described as being pear-shaped. This means their bodies are typically somewhat rounded, widening slightly before tapering down towards the rear end where the reproductive structures reside.
