Description
|
|
Species in the subgenus Dendrolasius are jet black colored in workers. Maxillary palpi are short, not reaching the neck.
|
Remarks
|
|
These are temporary social parasites of other Lasius species. They resemble each other, but the shape of petiole provides characters for taxonomic separation. Females are relatively easily distinguished. Nests are constructed of carton and are usually found near tree roots. The ants smell like "Sansho", a Japanese pepper. They form long-term trunk trails and attend aphids on trees.
Five species are known from Japan as follows: L. capitatus, L. nipponensis, L. morisitai, L. spathepus, L. teranishii.
