Fight mozzies with dragonflies

With dengue (and now the Zika virus) still on the rise despite our best efforts, we could perhaps consider other, more natural, solutions, like increasing the population of dragonflies in our midst to counter the mosquito menace.

Dragonflies are known to have a voracious appetite for mosquitoes. They are also beautiful to look at. Such "flying machines" are a marvel of nature - able to fly forward, backwards, upside down and hover.

Dragonflies eat mosquitoes at every stage of their development; that is why they are so effective.

Some countries such as South Korea have successfully used dragonflies to combat the scourge of mosquitoes, especially in areas where large bodies of water exist.

Increasingly, we have man-made reservoirs in our midst, so dragonflies are a solution worth looking at.

And since we already spend thousands of dollars landscaping our HDB heartland, perhaps we could also include dragonfly breeding spots in the plans.
