“…In the field, there are only short-distance flights of at most a few hundred meters between locally patchy milkweed (Asclepias curassavica and A. nivea) host plants. Long-duration tethered flight occurred at low frequency in laboratory experiments, and there was little evidence of response to photoperiod, in contrast to Iowa bugs (Dingle et al, 1980a(Dingle et al, , 1980b. The Puerto Rico bugs are also smaller than the Iowa bugs (although total fecundity is similar in these populations), and there are some other physiological and ecological differences between the Puerto Rico and Iowa samples (Dingle, 1981).…”

“…Artificial selection experiments tend to be of long duration, and correlations are limited to the selected trait, but they do reveal patterns of direct and correlated response to selection and provide additional evidence for genetic variation and covariation in a given environment. We chose wing length as the selected trait because it shows considerable geographic variation in O. fasciatus, because it differs in migratory and nonmigratory populations, and because it displays high values of additive genetic variance and thus should respond to imposed selection differentials (Dingle et al, 1980b; see also Palmer and Dingle [1986] for further rationale). Our results indicate that there are distinct differences in the genetic structures ofthe Iowa and Puerto Rico populations.…”

Abstract. -Genetic parameters were assessed in the nonmigratory Puerto Rico population of the milkweed bug, Oncopeltus fasciatus, and compared with parameters estimated in a migratory population from Iowa (Palmer and Dingle, 1986). Offspring-parent regression analysis provided initial estimates of heritabilities and phenotypic and genetic correlations among wing length, headcapsule width, female age at first reproduction, fecundity for the first and second five days of reproduction by females, and clutch size for the first and second five days of reproduction by females. Replicated bidirectional selection for wing length was then imposed, with a direct response to selection revealing substantial additive genetic variance for this trait, as was also the case with the Iowa population. Assays for correlated response to selection yielded two further similarities to Iowa: a positive response in head-capsule width and no consistent response in age at first reproduction. In contrast to the results with Iowa bugs, neither regression analysis nor selection revealed statistically significant genetic correlations between fecundity measures and those of other traits. In both populations the potential exists for body-size characters to evolve together independently ofage at first reproduction; but in the nonmigratory Puerto Rico bugs, fecundity does not contribute to a life-history syndrome involving genetic correlations among these traits.

“…During laboratory culture, a tends to decrease (Dingle et al, 1977). Since laboratory-bred descendants of field populations have been used in all previous work (and in the present study), the shorter a reported in the previous study (Dingle et al, 1980a) may be attributable to artificial selection imposed by laboratory culture conditions. Iowa O. fasciatus collected in years subsequent to my 1981 collections have alphas similar to those found in the present study (J. D. Baldwin, pers.…”

“…Although previous studies (Dingle et al, 1980a(Dingle et al, , 1980b Dingle and Baldwin, 1983) have examined samples of populations from several geographic areas, this study is the first to sample all populations in the same year and examine them simultaneously in the laboratory. This procedure attempts to avoid complications due to random fluctuations in life-history traits among natural populations (across years) and minimizes the effect that uncontrolled fluctuations in the laboratory environment may have on population comparisons.…”

“…It is found in the middle latitudes of North America only during the summer and early fall. In past studies of this insect, the major emphases have been on quantifying phenotypic variation in life-history traits among populations (Dingle et al, 1980a(Dingle et al, , 1980bDingle, 1981;Evans, 1982) and on quantitative-genetic studies assessing the level of variation (heritabilities and genetic correlations) within populations from Iowa and Puerto Rico (Dingle et al, 1977(Dingle et al, , 1988Hegmann and Dingle, 1982;Palmer, 1985;Palmer and Dingle, 1986;Dingle and Evans, 1987). In this report, the life-history characteristics ofintra-and interpopulation crosses of laboratory-bred descendants of six geographic populations of O. fasciatus are examined and compared with previously reported data.…”

GEOGRAPHICAL AND GENETIC STRUCTURE OF LIFE‐HISTORY VARIATION IN MILKWEED BUGS (HEMIPTERA: LYGAEIDAE: ONCOPELTUS )

Abstract. -Life-history variation was investigated using crosses within and among the laboratorybred descendants of six geographic samples ofthe large milkweed bug, Oncopeltus fasciatus. These samples spanned the species' range, from permanent (year-round) populations on tropical islands to seasonal middle-latitude populations found in temperate North America. The seasonal populations must be refounded each year by colonists from more southern populations. Marked differences in life-history traits (particularly in age at first reproduction, clutch size, and rate of egg production) were observed among the six population samples, with tropical-island and west-coast populations being the most distinct. In the eastern and central United States, there was a marked north-south difference in life history. Crossing experiments demonstrated a genetic basis for these differences. F, and F 2 hybrids from crosses between continental populations tended to have intermediate phenotypes. The similarity of the seasonal middle-latitude populations' life histories and the consistency of the distribution of life-history characteristics among populations (across years) may indicate that the north-south difference in life history is due to selection on these traits during the annual northward movement or that migrants represent a distinct genetic form of this species.

Regional populations of geographically widespread species may respond to different environmental factors across the species' range, generating divergent effects of climate change on life-history phenology. Using thousands of citizen science observations extracted from iNaturalist and associated with corresponding temperature, precipitation, elevation, and daylength information, we examined the drivers of adult mating and of nymphal phenology, development, and group size for populations of the large milkweed bug, Oncopeltus fasciatus, in different ecoregions. Research-grade iNaturalist images were correctly identified 98.3% of the time and yielded more than
