Fig. 2 a–c in Non-ecological speciation, niche conservatism and thermal adaptation: how are they connected?
Fig. 2 a–c. Strong sexual isolation between two congeneric species of demoiselles (Odonata: Calopteryx) in Europe. a These two species differ mainly in the male's secondary sexual character (amount of wing melanization, while females of both species are very similar. The banded demoiselle (C. splendens) has about 50 % of the wing covered with melanin, whereas the beautiful demoiselle (C. virgo) has almost the entire wing melanized. b At a sympatric locality in southern Sweden ("Klingavälsåns Naturreservat") these two species are strongly sexually isolated from each other and mate assortatively, although a few heterospecific pairs are found. c Experimental manipulation of
Fig. 5 a–c in Non-ecological speciation, niche conservatism and thermal adaptation: how are they connected?
Fig. 5 a–c. Mate preferences and species recognition is learned, rather than purely genetic among females of the banded demoiselle (C. splendens). a Female C. splendens discriminate between con- and hetero-specific males based on a visual cue: the amount of wing melanization (see also Fig. 2). Females (middle, below the two males) were allowed to choose and/or physically interact with either con- or hetero-specific males, and their mate responses were recorded (b, c). b Species discrimination is not present among sexually naïve C. splendens females that have been isolated since emergence from males of both species, but is present among sexually experienced females that have interacted with males in the field.

Fig. 4 a–c in Non-ecological speciation, niche conservatism and thermal adaptation: how are they connected?
Fig. 4 a–c. Sexual and natural selection on 12 morphological traits in the banded demoiselle (C. splendens), based on field observations of mating success of marked individuals. a Sexual selection is stronger than natural selection across all traits, irrespective over which time scale sexual selection is measured ("short" vs "long", referring to minutes and hours vs days). b Natural selection on the morphological
Fig. 3 a–c in Non-ecological speciation, niche conservatism and thermal adaptation: how are they connected?
Fig. 3 a–c. Weak interspecific thermal niche divergence between phenotypically and ecologically similar demoiselles (C. splendens and C. virgo). a Thermal images obtained from infrared (IR) photographs of demoiselles can be used to obtain accurate estimates of body temperatures, ambient temperatures and substrate temperatures. Here a copulating pair of C. virgo (pair in middle of figure). Note the white colour of the male, which reveals his substantially higher body temperature than the substrate (temperature scale on the right). b Interspecific niche divergence between C. splendens and C. virgo in minimum thorax temperature, substrate temperature, maximum substrate temperature and ambient temperature at a sympatric site ("Klingavälsåns Naturreservat" in southern Sweden).
