Thoracic and abdominal temperatures (Tth and Tabd) of Diceroprocta apache were monitored during exposure to an ambient temperature (Ta) of 45.5 C in dry air. Mass-specific heating constants averaged 0.36 ± 0.036 min g⁻¹ below body temperature (Tb) of 39-40 C, but above that temperature range heating constants decreased to 0.012 ± 0.002 min g⁻¹ as a result of evaporative cooling. After 1 h exposure to 45.5 C, Tb's were still ≥2.9 degrees C below Ta. Tb's maintained by cicadas in these… 
Thermoregulation and evaporative cooling in the cicada Okanagodes gracilis (Homoptera: Cicadidae).
TLDR
O. gracilis is the first cicada reported that is able to continue activity while simultaneously feeding and evaporatively cooling and the possible thermoregulatory value of the species' coloration is discussed.
Evaporative cooling and endothermy in the 13-year periodical cicada, Magicicada tredecem (Homoptera: Cicadidae)
TLDR
The location of the abdominal pore tracts is such that extrusion of water through the ducts may preferentially cool the heart and perhaps other abdominal tissues, and an hypothesis is proposed to account for the diversity of body temperature setpoints in cicadas.
Thermoregulation and endothermy in the large western cicada Tibicen cultriformis (hemiptera: cicadidae)
Abstract 1. Measurements of body temperature (Tb) in the field demonstrate that Tibicen cultriformis (Davis) regulates Tb through a combination of behavioral mechanisms and endogenous heat
Evaporative cooling in the desert cicada : thermal efficiency and water/metabolic costs
Using plant xylem water for evaporative cooling, the desert cicada Diceroprocta apache can maintain a body temperature as much as 5°C below ambient ( T a =42°C). Simultaneous measurements of water
Cloacal evaporative cooling: a previously undescribed means of increasing evaporative water loss at higher temperatures in a desert ectotherm, the Gila monster Heloderma suspectum
TLDR
The results show that Gila monsters have high EWL rates relative to body mass and emphasize the potential value of EWL for thermoregulation in ectotherms and demonstrate for the first time the role of the cloaca in this process.
Regional Differences in Cuticular Permeability in the Desert Cicada Diceroprocta Apache: Implications for Evaporative Cooling
TLDR
These findings confirm that the large pores are the routes by which water reaches the surface and that the temperature at which this active extrusion of water begins corresponds to the point where cicadas must seek milder microclimates to prevent body temperature from reaching lethal levels.
Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
TLDR
Endothermy in cicadas may serve to uncouple reproductive behavior from environmental constraints; to circumvent possible thermoregulatory problems; to permit the utilization of habitats unavailable to strictly ectothermic cicada; to reduce predation; and to optimize broadcast coverage and sound transmission.
Temperature regulation by evaporative cooling in a desert grasshopper, Calliptamus barbarus (Ramme, 1951)
Abstract 1. 1. We examined the desert-dwelling grasshopper, Calliptamus barbarus, to determine whether it used evaporative cooling, and if differences existed in the use of evaporative cooling
Temperature regulation by respiratory evaporation in grasshoppers.
Grasshoppers of the species Schistocerca nitens (Thunberg), Locusta migratoria (L.) and Tmethis pulchripennis (Bolivar) are able to withstand air temperatures higher than lethal internal temperature
Not all cicadas increase thermal tolerance in response to a temperature gradient in metropolitan Seoul
TLDR
This research is the first to detect a variation in thermal responses and body size of H. fuscata individuals at a local scale and to better understand the adaptation mechanisms of insects linked to UHI effects.

Temperature Responses of the Desert Cicada, Diceroprocta apache (Homoptera, Cicadidae)
TLDR
In temperate climates the thermal load upon the insect usually permits sufficient warming for full activity, and only at midday are insects forced into shade, but the desert cicada, Diceroprocta apache, faces a different situation.
Keeping a Cool Head: Honeybee Thermoregulation
TLDR
Honeybees regulate head teriperature by evaporative cooling of regurgitated honeycrop contents by means of passive conduction and physiological facilitation resulting from accelerated blood flow, which permits flight at the extraordinarily high ambient temperature of 46�C without overheating the head and thorax.
Electron paramagnetic resonance spectroscopy of spin-labelled cuticle of Centruroides sculpturatus (Scorpiones: Buthidae): Correlation with thermal effects on cuticular permeability
TLDR
EPR spectra of spin-labelled cuticle indicate that the epicuticular lipids are very mobile at ambient temperature, with the translational diffusion coefficient being about 5 × 10−6 cm2 sec at 22 C, and that the low-temperature transition is associated with an increase in mobility of the hydrocarbon chains of the Epicuticular Lipids.
Water transport in perfused scorpion ileum.
TLDR
Water transport in desert scorpion ileum appears to be adaptive, as scorpion dehydration results in alterations of luminal ion concentrations that favor increased net flow of water to the hemolymph.
Cuticular lipids of adults and nymphal exuviae of the desert cicada, Diceroprocta apache (homoptera, Cicadidae)
TLDR
Hydrocarbons were the most abundant lipid constituent in the cuticles of nymph (exuviae) and adult desert cicadas, Diceroprocta apache, and this difference is correlated with the increased transpiration potential experienced by the adult.
Cuticular Permeability and Epicuticular Lipid Composition in Two Arizona Vejovid Scorpions
TLDR
The results indicate that cuticular permeabilities can be altered to meet environmental requirements, and that in scorpions predictable changes in epicuticular lipid composition are in part responsible.
