The study was to examine the variation and pattern of colony components of Vollenhovia emeryi. The total of 38 colonies was collected from 10 locations, including 35 colonies from 9 locations in South Korea and 3 colonies from 1 location in USA. To know colony components variation, we studied the approximate colony size, the approximate number of reproductives: queens, gyne and male, the approximate number of brood during 7 months. The observation period was from September 2012 to March 2013 over the breeding season from July to August. As a result, the study has found that colony components of the 38 colonies are not constant. This also indicates that gynes and males appear during non-breeding season at least in the laboratory condition. There are 4 types of gynes and males emergence: both(31.6%), only gynes(2.6%), only males(28.9%), absence(28.9%). The number of gynes and males of each colony also shows variance. It indicates that Vollenhovia emeryi may show colony components continuum. In this species, fertilized eggs become worker females and males; worker females are diploid but males are haplid because of maternal genomic elimination. Unfertilized eggs become queens which are diploid by clonal reproduction. Therefore, each individual of the sex can exceptionally transfer its own genes. This unique haplodiploid sex determination may create the conflict between queen and male and cause colony components continuum.
