Endothermy during terrestrial activity in large beetles

C A Bartholomew, T M Casey

    Science (New York, N.Y.)
    |March 4, 1977
    PubMed
    Summary

    Large tropical beetles can internally warm their bodies significantly above ambient temperatures for extended periods. This thermoregulation supports terrestrial activity and flight, similar to mammals.

    Area of Science:

    • Insect physiology
    • Thermoregulation in arthropods
    • Bioenergetics

    Background:

    • Large tropical beetles, Strategus aloeus and Stenodontes molarium, inhabit diverse environments.
    • Understanding insect thermoregulation is crucial for ecological studies.

    Purpose of the Study:

    • To investigate the capacity of S. aloeus and S. molarium for endogenous thermoregulation.
    • To quantify the thermal differences maintained by these beetles relative to ambient temperature.
    • To assess the metabolic implications of their thermoregulatory strategies.

    Main Methods:

    • In vivo measurements of metathoracic temperatures in beetles.
    • Monitoring of ambient temperatures over extended periods.
    • Measurement of oxygen consumption during different activity states.

    Main Results:

    • Beetles maintained metathoracic temperatures 5-7°C above ambient for hours.
    • Terrestrial activity was associated with elevated metabolic rates, comparable to mammals.
    • Pre-flight and flight periods involved an additional 8-10°C temperature increase.

    Conclusions:

    • These beetles exhibit significant endogenous thermoregulatory capabilities.
    • Thermoregulation is vital for both sustained terrestrial activity and preparation for flight.
    • The metabolic cost of thermoregulation is substantial, supporting active lifestyles.
