| Pheidole sykesii|
A large species occurring in India, Pheidole sykesii throws up concentric embankments round the entrance to the nest (see image below); the extent of these earthworks varies according to the circumstances, from a mere single tube, less than 25mm high in flat dry country, to half-a-dozen concentric rings, the centre tube 75mm and more high, each ring decreasing in height, and the outside ring 450mm in diameter. Moreover, when the nest is on a slope, the up-hill half of a ring is always considerably higher than the other. Pheidole wroughtonii and Pheidole latinoda also build these earthworks, but they are always rudimentary compared with those of P. sykesii (Wroughton, 1892).
