What do CPUs, stockbrokers, and
butterflies have in common? They are good at investing their resources in the
right place at the right time so as to maximize their returns! Trade-offs are a
way of life for butterflies and other small insects that must budget their
energy between numerous morphological features and activities during their
short lifespans. Time, food, and space are always at a premium, and optimizing
resource use is particularly important for migratory butterflies that must
prepare for arduous journeys in uncertain environments. A new study by
researchers at the National Centre for Biological Sciences (NCBS-TIFR,
Bangalore) reports on butterfly migrations in peninsular India and explores the
effect of migration on resource investment strategies of migratory butterflies.
It reveals that migration affects the morphology and physiological states of
female butterflies much more prominently compared to that of males.
