The
Curry Moth
The
curry moth, Samia aromii, is
closely related to the Ailanthus silkmoth, Samia cynthia,
and commonly found throughout southern India. It's
large size, as well as delicately coloured wings, have long made it a
species of interest for collectors, but it is only recently that its
culinary properties have been discovered. Or, to be more precise,
re-discovered.
The
curry moth, like most moths and buterflies, only lays its eggs on
specific plants that meet the requirement of the soon-to-be hatched
larvae. In the case of the curry moth, it looks for plants that have
a relatively high concentration of capsaicin, the “spicy”
molecule of chili peppers. As a result, they are mostly found on the
spice plantations that grow chilis, or on wild plants of the same
variety.
When
the British East India Company took over India in 1757, they also
took control over the spice trade and production. Due to poor
communication with locals, which was due as much to arrogance as
incompetence, the british failed to see the curry moth as anything
but a pest, and ordered farmers to dispose of the insects trying to
breed on their crops. Later, as pesticides and herbicides were
introduced, the curry moth population suffered an even more drastic
fall, and in 2005, the species hit its all-time low, now
being found only in the wild.
However, recent efforts to
introduce biological agriculture in the region have seen a revival of
the moth, and local population have kept the memory of the moth, and
its uses which eluded the british, alive until today.
In
fact, due to its restrictive regime, the curry moth was often used by
local s as a seasoning in and of itself. The moth larvae absorbs much
of the aromatic molecules of its food, especially
the capsaicinoids, and stores them in its body, possibly to deter
predators. This, however,
did not work well on humans, who quickly discovered that the subtly
modified spice produced by the moth was even more enjoyable than that
of the plants themselves. But
as the moths started
disappearing due to the chemicals used in the fields, they
disappeared from peoples food, too.
The
rediscovery of the curry moth as a seasoning, however, has
not only caused a
cultural revival in India,
but a culinary revolution in
the west as well. What was
inconceivable to british colonialists (namely, eating insects) is
commonplace for the modern “foodie”, and the moths are starting
to appear in more and more high-end restaurants in the western
hemisphere. This, in turn, encourages indian spice farmers to reduce,
or eliminate, the use of chemicals in their fields, allowing them to
switch to biological methods of cultivation and increase their
profits at the same time, the moths now fetching much higher prices
than the spices themselves.
