Table 1.

Diversity of social parasites in the genus Formica compared to all other ants

	Temporary social parasites (%)	Dulotic social parasites (%)	Permanent social parasites (%)	Total social parasite diversity (%)
All ants (n = 13,861)	200 (1.4)	80 (0.6)	100 (0.7)	>400 (2.9)
Formica (n = 172)	68 (39.5)	14 (8.1)	2 (1.2)	84 (48.8)

Socially parasitic life histories are significantly overrepresented in Formica ants, except for inquilinism. The total social parasite diversity in ants is higher than the sum of species in individual life history categories because the biology of numerous social parasites remains unknown. The data are derived from published sources (1, 3, 4, 55).
