Nothing is known about the biology of Camponotus ashokai.

Identification

Karmaly & Narendran (2006) - This species comes close to Camponotus angusticollis in general appearance and in the following features: 1. Head elongate; 2. Antennae elongate, slender, filiform, 12 jointed; 3. Circular anal orifice at the apex of last gastral segment guarded by guard hairs. However this new species differs from Camponotus angusticollis in having: 1. Anterior margin of clypeus somewhat rounded, not dentate (in Camponotus angusticollis anterior margin of clypeus transverse and dentate). 2. Eyes oval, convex, black at the center, surrounded by greyish brown (in Camponotus angusticollis eyes convex oval, black); 3. Metanotum not gibbous (in Camponotus angusticollis metanotum gibbous); 4. Apex of pedicel flattened (in Camponotus angusticollis apex of pedicel cylindrical); 5. Node of pedicel convex anteriorly, flat posteriorly, rounded above (in Camponotus angusticollis node of pedicel thick at front, flat at base, very concave above, upper margin transverse and notched).
