Ephemeroptera: Baetidae of Gunnison County, Colorado

Callibaetis ferrugineus hageni
Speckled Wing Dun

Eaton, 1885

Updated 17 July 2016
TSN 609704

This female has been laying eggs, you can tell by the split near the back of her abdomen. After living much longer than most Baetid mayflies, she is able to lay eggs that hatch immediately. The fancy word for that is ovoviviparity.

      The author worked in Beaver Ponds in the Upper East River Valley near the Rocky Mountain Biological Lab. Abstract: "Organisms live in spatially complex environments, and many species persist as regional metapopulations, where dispersal among local subpopulations occupying habitat "patches" may strongly influence ecological and evolutionary processes. Three generations of the mayfly Callibaetis ferrugineus hageni were studied in a beaver pond metapopulation in the Colorado Rocky Mountains. The biology of adults, and patterns of larval abundance, recruitment, development, and behavior were examined to determine how trout predators, larval behavior within ponds, and adult dispersal among ponds interact to influence individual mayfly fitness and metapopulation dynamics.
Adult female size was strongly associated with potential fitness (fecundity). Females became sexually receptive one stage sooner than most mayflies (subimago stage), which may influence male swarming behavior and longevity. In males, there was no clear relationship between size and mating success. Males swarmed at their natal pond, while females frequently dispersed among ponds. Females did not avoid ovipositing in ponds with trout.
Patterns of oviposition, larval recruitment, and adult emergence revealed demographic sources and sinks in the metapopulation. To test whether trout negatively impacted pond quality, trout densities were manipulated and pond quality was inferred from local mayfly population growth rates. The results provided evidence that trout predators affected patch quality such that ponds with high trout densities were sinks, while ponds with low trout density were sources or sinks. Further, mayfly populations in ponds with high trout density would quickly go extinct without immigration from source ponds.
Surprisingly, larvae did not exhibit adaptive anti-predator avoidance behaviors or adaptive life history shifts in the presence of trout chemical cues. The lack of response to trout predators may result from conflicting selection pressure for rapid development in temporary fishless habitats. Additionally, frequent dispersal between fish and fishless habitat types may inhibit the evolution of traits adaptive to sink habitats. Overall, the observed source-sink dynamic in the mayfly metapopulation resulted from a combination of adult dispersal, larval behavior, and the distribution of predators. Similar source-sink metapopulation dynamics may be common in other taxa with complex life cycles, especially insects with unselective oviposition or those with a "passive" dispersal stage (plants, marine invertebrates, and fishes)."

     Abstract: " Callibaetis ferrugineus (Walsh) and C. fluctuons (Walsh) nymphs moved from the shallow, peripheral area of a pond during the late summer and autumn to the deeper water where they overwintered. In the spring they returned to the peripheral area where they were found throughout the summer. C. ferrugineus and C. fluctuans are ovoviviparous. A relationship between ovoviviparity and seasonal movements of the nymphs is suggested. "

     They worked on Callibaetis collected near Fort Collins, CO. By labeling chloride solutions and exposing Calibaetis larvae to various salt solutions, they established that Callibaetis can absorb chloride from a hypotonic solution which is more dilute than their body fluids. This is important for osmoregulation in a freshwater environment.
