Weightlifting ant is photo winner
An amazing image of an ant lifting 100 times its body weight has won first prize in a science photography contest. The image shows an Asian weaver ant hanging upside down on a glass-like surface and holding a 500mg (0.02oz) weight in its jaws. It was taken by zoology specialist Dr Thomas Endlein of Cambridge University as he researched insects' sticky feet.
Percentage of biomass made up by ants...
According to Hölldobler and Wilson (1990), up to 1/3 (33%) of the terrestrial animal biomass (NOTE: not including aquatic animal, or terrestrial and aquatic flowering plants and microorganisms) was made up of ants and termites. A study made in Finland produced a terrestrial animal biomass of ants alone of 10%. In the Brazilian rain forest the biomass of ants exceeds that of terrestrial vertebrates by four times! Thus a figure for ants of 15% of all terrestrial animal biomass is not out of line.
On a sunny day I took a camera and set out to photograph something of the life of ants. At first I was no good as the ants moved very quickly and I was easily distracted. But gradually I was drawn to a group which was climbing up a nearby dandelion. They would each pull out one seed and then parachute to the ground. Unfortunately I could not photograph these moments well, but I did manage to get this one shot of the last few ants before they flew down.

Pheromones produced by healthy kings and queens normally suppress gonad development in "helper" classes, and when the kings and queens die, the pheromones disappear or diminish. As a result, suppression lifts and nonrelated, "sterile," helper offspring from both colonies are able to become new "reproductives" and assume the throne
