We studied the effect of morphological variation and basking posture on thermal
characteristics in the speckled wood butterfly Pararge aegeria (L.). The process of heating …

Butterflies regulate their internal thoracic temperature in order to optimize performance
activities (eg flight, foraging). Previous research has shown that butterfly wings, particularly …

Males of the speckled wood butterfly Pararge aegeria L.(Satyrinae), actively search for
females (“patrolling”) or wait for them at particular places (“perching”). Darker males are …

Poikilothermic animals are often reliant on behavioural thermoregulation to elevate core-
body temperature above the temperature of their surroundings. Butterflies are able to do this …

Behavioural thermoregulation of 3 Pieris butterfly species, P. rapae, P. melete and P. napi,
was examined in relation to the intensity of solar radiation. To evaluate solar radiation …

Body orientation and wing tilting in Hipparchia semele (L.) have been explained previously
both by the need for shadow‑minimization (crypsis hypothesis) and by the need to regulate …

Many diurnal lepidoptera rely on solar basking to achieve elevated thoracic temperature. We
examined the effects of wind, radiation, body orientation, and wing position on the thoracic …

Free and unnarcotized butterflies in a vertical basking position were exposed to radiation
from a halogen lamp. Warming rate and equilibrium excess temperatures were recorded by …

1. Most ectotherms have a complex life-cycle, yet the impact temperature has on
metamorphic development of adults is generally unknown. 2. In this study, pupal …

In this field study, I examine whether body mass affects flight behavior and thoracic
temperature (T th) in butterflies from a relatively cool environment (3,100 m high in the Sierra …
