In Europe, the genus is represented with six species (Aspöck et al. 2001, Canard 2004). One of them, Nineta guadarramensis (Pictet, 1865), is separated into two allopatric subspecies: N. guadarramensis guadarramensis (Pic¬ tet, 1865) (only in Spain) and N. guadarramensis principiae Monserrat, 1980 (rare and sporadic in several European countries except Spain). Canard et al. (1998) and Canard (2004) consider the two subspecies to be valid species. In Switzerland, four of the six European species were known so far. The most common species is Ninetaflava (Scopoli, 1763), developing on deciduous trees, fol¬ lowed by N. pallida (Schneider, 1846), restricted to coniferous trees, and N. vittata (Wesmael, 1846), which is mostly found on deciduous trees. N. inpunctata (Reu¬ ter, 1894), on the other hand, is a rare species in Europe (Aspöck et al. 1980), with only two localities known for Swit...

They can be yellow (autosomal recessive mutant); change from whitish-yellow to green as young adults; or temporarily turn yellowish, reddish, or brown during diapause. New findings on a yellow mutant in a natural population in southern California and on species-specific diapause coloration are presented, old findings are reviewed, and the adaptive value of color variability and color change in the genus is discussed.
