Tears for food
Tear-feeding moths and butterflies
in Africa and Asia and South America
feed on large placid animals
deer antelope crocodiles
which cannot readily
brush them away
In Madagascar there are
no such large animals
Birds can fly away
but not when sleeping
The Madagascan moths
can be seen on the necks
of sleeping magpie robins
and red-tailed newtonia
the tip of their proboscis
inserted under the bird’s eyelid
avidly supping for the sodium
in the tears
As the birds have two eyelids
both closed
instead of the soft
straw-like mouthpart
found on tear-drinking moths elsewhere
the Madagascan moth
has a harpoon-shaped proboscis
with hooks and barbs
which it inserts and secures
under the bird’s eyelids
without disturbing the bird
The Madagascan tear-drinkers
all male
derive most of their nutrition
from tears :
take from this observation
what you will
