But for ingenuity, the Latrine blowfly may very well take the cake."The Latrine blowfly is a warm-weather insect best known for depositing its eggs on dead animals.And they observed that the reddish coloured bubble -- growing to almost double its head size -- cooled rapidly, "down to as much as eight degrees Celsius (14.Other functions may include digestion.This "bubbling behaviour", he told AFP, appears to be "a very effective way for blowflies to promote evaporative cooling and, therefore, lower their body temperature.0 C, 0.The flies blew more bubbles as air temperature increased, but fewer in humid surroundings where moisture in the air hampers evaporation, the team observed.2 C respectively" -- and more after repeated efforts.

Andrade and a team used infrared heat imaging cameras to look for any temperature changes on the fly&disposable facial mask Factory39;s body during "bubbling behaviour".Humans sweat, dogs pant, cats lick their fur..Other insects may use the same method as the latrine fly, suggested the team, but only those that can blow a big enough bubble relative to their body size.Put together, the observations serve as "compelling evidence" that bubble-blowing is used, at least partly, to regulate body temperature, said Andrade.4 degrees Fahrenheit) below ambient temperature, within about 15 seconds," the researchers wrote."As the fluid moves out, evaporation occurs which lowers the fluid temperature, the fly then moves the cooled droplet in, # which cools off the body temperature of the fly," explained Denis Andrade of the Sao Paulo State University in Brazil, who co-authored a study in the journal Nature Scientific Reports.

While sweating and panting is an effective cooling method for mammals and birds, body surface evaporation is tougher for insects with their hard, wax-covered external skeletons.To cool down, it blows bubbles with its stomach juices through its mouth, and then sucks them back in, scientists revealed on Thursday. Animals have adopted an interesting array of techniques for regulating body temperature through evaporation.The fly's bubble-blowing has been observed before, but its function has remained a mystery up until now.5 C, and 0."Blowflies then re-ingest the cooled droplet, which lowers the temperature of the fly's head, thorax and abdomen by 1
