“…In the current study, less orange pigment developed at low nutrient levels, suggesting that there may be a physiological cost of being orange in addition to any behaviourally mediated life history costs. In the flour moth Ephestia kuehniella , non‐melanic females live significantly longer than females of the melanic genotype, a difference which may be explained by the higher activity rates of melanic compared to non‐melanic genotypes ( Verhoog et al . 1998 ).…”

Males of the damselfly Mnais costalis Selys (Odonata: Calopterygidae) are morphologically and behaviourally polymorphic, typically existing as clear‐winged non‐territorial ‘sneaks’ and orange‐winged territorial ‘fighters’. The amount of orange pigment in the wing, as measured with a chromameter, varied between individuals, and decreased as the reproductive season progressed. Young individuals maintained in the laboratory on high or low nutrient diets differed in the amount of pigment that developed in the wing. Males in the high nutrient group developed darker wings faster than those in the low nutrient group. Young adults of both sexes and morphs were fed 14C‐radiolabelled tryptophan or tyrosine (precursors of the pigments ommochrome and melanin, respectively). Ommochrome was restricted to the pseudopterostigma of the males of both morphs and was not present in females. The presence of tyrosine in the wing cells of orange males, but not of clear males, indicated that the orange pigment is at least partly constituted from melanin. These data show that at least some pigment levels must be maintained continuously in the wings of orange males, and that maintenance is costly as it is compromised at low nutrient levels.

“…On the basis of laboratory selection experiments, Dombeck and Jaenike (2004) demonstrated genetic variations for abdominal spot number polymorphism in Drosophila falleni and found that individuals without abdominal spots are nearly twice as susceptible to nematode infection as the spotted wild-type flies. In Adalia bipunctata (coleopteran) and Ephestia Kuehniella (lepidopteran), melanics display higher mating success compared with typicals (Verhoog et al 1998).

“…Melanin patterns are involved in diverse aspects of ectothermic insect ecology (Majerus 1998;Rajpurohit et al 2008). Field and laboratory studies in moths, butterflies, and beetles have proposed that melanization patterns play a role in thermoregulation (Majerus 1998), desiccation resistance (Safranek & Riddiford 1975), and mating success (Verhoog et al 1998).

We investigated eight populations of Drosophila immigrans from low to high montane localities (600–2202 m) for altitudinal variations in abdominal melanization and fitness‐related traits (desiccation resistance, copulation duration, and fecundity). On the basis of common garden experiments, persistence between‐population differences at 21°C suggests that observed variations in fitness‐related traits have a genetic basis. Parent–offspring regression analyses showed higher heritability (h2= 0.77) for melanization patterns on all the abdominal tergites. All the traits showed significantly higher repeatability across generations. Under colder and drier environments in dispersed montane localities, abdominal melanization and desiccation resistance significantly increased (1.5–1.9 fold) along altitude. Thus, there are correlated effects of abdominal melanization on desiccation resistance. Genetic correlations, based on family means, were significantly high between abdominal melanization and other fitness traits. Furthermore, darker flies along increasing altitude resulted in a 35–40% increase in copulation duration as well as fecundity. There are significantly positive correlations of abdominal melanization with copulation duration as well as fecundity on the basis of within‐ as well as between‐population variations. Such observations are in agreement with the thermal budget hypothesis. Present data suggest that changes in body melanization impact fitness‐related traits in montane populations of Drosophila immigrans.
