The rains are the harbinger of life in this
region and no other species group defines this more than the Odonates or Dragonflies and Damselflies.
During these months they are everywhere, in every kind of water body, both
permanent and short-lived, running and still, pure and dirty. It’s as if the Dragonflies
have taken over our tiger reserve as ‘tigers of the sky’ and will continue to
do so till the attention moves back to the striped cats in October.
Kanha goes through a magnificent
transformation between July and September. The Southwest Monsoons
are unleashed on this landscape thanks to the barrier created by the Maikal
Hills. The rain comes in spurts that
could last between a few minutes to a few
days, with cloudy or sunny breaks in between. It is impossible to travel this
landscape on jeeps, leading to the closing down of national park for three
months. But for the keen Nature enthusiast, this is the best time to visit the
region.

The rains transform the landscape. Farmland turns emerald with rice plantations, seasonal streams swell with a gushing flow, and
depressions in the ground become puddles and ponds. The barren land gets
carpeted with green grasses and reeds forming shallow marshes, and of course,
the rivers and lakes, that were barely a trickle in the summer months, go back
to their majestic best. Even within and around SALBAN, the rain water takes
over the rice fields, the pond in front of the house, and the channels created
for excess water flow into the two large lakes on either side of the property.
Rain water is everywhere (except inside the house)!
We
have noticed different species of Odonates in different kinds of water bodies. The flooded
grasslands and reeds in the water’s edge are covered with slender damselflies.
The larger bushes and the low trees provide perches for the high flying
dragonflies. Even old stumps and drift wood become fascinating spots to observe
these aerial hunters when they take a break to feed or clean themselves. One
piece of wood by the lake played host to a common
clubtail, a crimson-tailed marsh hawk, a blue marsh hawk, an orange marsh dart
and a fulvous-forest skimmer, all in
a span of ten minutes.
We
see dragonflies even in our own patch of Sal trees, far away from the water
bodies. Some species prefer to live their life
away from water and visit the water sources only during breeding time. We often see the males carrying females from drier land to their breeding pools to
mate and lay eggs. How they lock themselves up in this dance is definitely
nothing short of a natural wonder. Studies show that the lock is so perfect
that it is possible only between members of the same species.

After the monsoons, you may have noticed the mass emergence of literally thousands of dragonflies. They
fill up the sky in vertical stacks, especially around open fields, water pools
and in forest clearings. Many of us may not know that these reddish dragonflies
(females are yellowish), known as globe skimmers or wandering gliders (Pantala flavescens) migrate large distances along with the monsoon winds, making for one of the most
spectacular insect migrations recorded. They congregate in big numbers and are
believed to travel an amazing 12,000 miles every year using the tropical
weather system. This journey is known to be completed by two generations of
dragonflies. Many studies are being carried out to
understand this migration, but it is only a matter of time before it is
revealed as one of the greatest natural history spectacles on this planet.
