Crematogaster lineolata

Nests under logs and in stumps. Their diet includes dead insects and liquids collected from tended Homoptera, with a decided preference for those kept on plant roots. Crematogaster lineolata is aggressive and can have an annoying bite. (Mackay and Mackay 2002)

Identification
The workers of this species have numerous hairs on the pronotum, at least two on the mesonotum and usually at least two on the propodeum or propodeal spines. The side of the mesosoma is roughly sculptured with striae and punctures, most surfaces are dull, although the central region of the side of the pronotum may be weakly shining (but still is sculptured). The top of the mesosoma is roughly sculptured with striae/rugae and scattered punctures. The sides or the head are roughly sculptured with striae and scattered punctures, the central region is partially smooth, although is only moderately shining. (Mackay and Mackay 2002)
