The Flying Saucer At Sunset

Lenticular clouds (Altocumulus lenticularis) are stationary lens-shaped clouds with a smooth layered appearance that form in the troposphere, usually above mountain ranges. One was spotted in Singapore recently...

Eyes Of 30,000 Honeycombs

With 30,000 individual facets, dragonflies have the most number of facets among insects. Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture...

A Kaleidoscope Of Colours, Shapes And Patterns

Spectacular and innovative in design, the Flower Dome replicates the cool-dry climate of Mediterranean regions like South Africa, California and parts of Spain and Italy. Home to a collection of plants from deserts all over the world, it showcases the adaptations of plants to arid environments...

Lightning Strikes, Not Once, But Many Times

Unlike light, lightning does not travel in a straight line. Instead, it has many branches. These other branches flashed at the same time as the main strike. The branches are actually the step leaders that were connected to the leader that made it to its target...

Are You My Dinner Tonight?

A T-Rex has 24-26 teeth on its upper jaw and 24 more on its lower jaw. Juveniles have small, sharp blade-shaped teeth to cut flesh, whereas adults have huge, blunt, rounded teeth for crushing bones. Is the T-Rex a bone-crushing scavenger?

Central Catchment Area - Termites vs Ants

Central Catchment Nature Reserve
North, Singapore
August 2013

It was one of the cooler days out there when termites and ants abound in the Central Catchment Nature Reserve.

Both ants and termites live in colonies or nests where one or relatively few individuals reproduce while non-reproductive individuals cooperate to care for brood, maintain the nest, and defend the colony. These features - reproductive division of labor (only the queens lay eggs), overlapping generations (you have all ages in the nest), and cooperative brood care (all individuals care for the young, not just the queens) - are hallmarks of eusociality, a condition achieved in relatively few insects. 

These are termites. They have straight antennae that appear like a string of tiny beads. In termites the body segments are much more broadly attached.


And these are ants. They have elbowed antennae, where the first segment is much longer than the segments that follow. Ants also have a characteristically constricted "waist" while termites do not.

The most obvious difference is that termites usually avoid light, and are usually visible only before noon when the sun is still not too hot.

Elimination - The best way to get rid of termites, which probably explains why the NParks contractor was hacking this bit of termite-trailed wooden boardwalk out...

Some other interesting finds - a red-eyed fly, a slim wasp and a limping long-tailed macaque...
