Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)

Temperature responses and habitat selection by mangrove cicadas in Florida and Queensland (Hemiptera Cicadoidea)

“…The differences in the general morphology of Diceroprocta and Arunta may be responsible for the observed differences in the minimum flight temperatures. The minimum flight temperatures of the Arunta species studied are similar to endothermic species from North America (SANBORN 2000), South America (SANBORN et al 1995b), and South Africa (SANBORN et al 2003a). The minimum flight temperature of D. biconica is similar to both endothermic species (SANBORN et al 1995a(SANBORN et al , 1995b(SANBORN et al , 2003a as well as an ectotherm whose southern distribution is a little north of the Florida Keys (SANBORN 2000).…”

“…The absolute values determined for the shade seeking temperatures are some of the lowest values determined for cicadas with the mean of A. interclusa being the lowest value reported to date. Mangrove cicada shade seeking temperatures are lower than other coastal species that inhabit the grasses on an open shore (SANBORN & PHILLIPS 2001) or an endothermic platypleurine cicada, Platypleura capensis (Linné 1764), inhabiting the Coastal Renosterveld from South Africa (SANBORN et al 2003a) but are similar to endothermic species which are active in the understory of forests (SANBORN et al 1995b, SANBORN 2000 and an ectotherm active early in the season when ambient temperatures may be low (HEATH 1967). Perhaps the convective cooling from ocean breezes combined with their preferred perch sites was a selection factor in the lower thermal preferences.…”

Thermoregulation and the influence of body temperature on calling song parameters in Cicada orni (Hemiptera: Cicadidae)

“…Similar relationships between Tb and Ta have been found in both ectothermic and endothermic cicadas from North America, South America and Africa (Sanborn, 2000(Sanborn, , 2004Sanborn & Maté, 2000;Sanborn et al, , 1995bSanborn et al, , 2002bSanborn et al, , 2003Sanborn et al, , 2004Villet et al, 2003). However, unlike the relationship seen in Diceroprocta olympusa (Walker, 1850) (Sanborn & Maté, 2000), the thermoregulatory behavior of C. orni more closely resembles what was observed in the desert cicada Okanagodes gracilis Davis, 1919 in that Tp is not a better predictor of Tb than Ta.…”

“…The slope of the regressions of C. orni are greater than any other analysis performed in cicadas (Sanborn, 2000(Sanborn, , 2004Sanborn & Maté, 2000;Sanborn et al, , 1995bSanborn et al, , 2002bSanborn et al, , 2003Sanborn et al, , 2004Villet et al, 2003) with the exception of one subset of data in an endothermic species which included partially as well as fully active animals (Sanborn, 2000). As Ta increases, there is an increase in the Tb range of active animals in the field.…”

Hot-blooded singers: endothermy facilitates crepuscular signaling in African platypleurine cicadas (Hemiptera: Cicadidae: Platypleura spp.)

“…Most cicadas are ectotherms that use solar radiation to regulate T b (see summary in Sanborn 2002). However, endothermy is a physiological thermoregulatory strategy used by some New World cicada tribes (Bartholomew and Barnhart 1984;Sanborn et al 1995aSanborn et al , 1995bSanborn 1997;2000). We describe and quantify endothermic behavior in several species of African cicadas of the genus Platypleura Amyot & Serville.…”
