A prerequisite for honest handicaps is that there are significant condition–dependent costs
in the expression of sexual traits. In the wolf spider Hygrolycosa rubrofasciata (Ohlert) …

Conditional handicap models of sexual selection predict that sexual traits are reliable
signals of male quality because they are (a) condition dependent and (b) costly to produce …
