From: Triatominae: does the shape change of non-viable eggs compromise species recognition?
Egg viability. Examples of viable (left) and non-viable (right) eggs of Panstrongylus chinai, P. howardi, Triatoma carrioni and Rhodnius ecuadoriensis. The non-viable eggs show eggs with yolk only (lacking of obvious development signals, as in P. chinai) (a); embryo in normal development (as in P. howardi) (b); embryo with malformations (development alteration, as in T. carrioni) (c) or a deflation-like deformation after 25 days of development (as in R. ecuadoriensis) (d). Abbreviations: P, Panstrongylus; T, Triatoma; R, Rhodnius
