Holarctic distributions of lineages with eusocial behavior can be explained by migration as solitary populations from Eurasia to North America across Pleistocene Bering land bridges, with re-expression of double-brooded, eussocial behavior when the species then extended their ranges southward in North America.

SummaryMales of the wool-carder bee, Anthidium manicatum, patrol clumps of garden plants. Females of this species visit these plants for pollen, nectar, and pubescence; they also mate there. Females…
Evolution and Life-History Patterns of Mites Associated with Bees
- G. C. Eickwort

- 1994
All species, except cleptoparasites (cuckoos), construct nests and provision cells with pollen and concentrated nectar (honey), the sole food of both larvae and adults, otherwise occupied only by a few vespid wasps.

This chapter provides the first review of the diversity and biology of all mites associated with all taxa of social insects, and places the important associates into currently accepted families and genera.
Tribal Positions of Western Hemisphere Green Sweat Bees, with Comments on Their Nest Architecture (Hymenoptera: Halictidae)
- G. C. Eickwort

- 15 May 1969
The generic assignments of 6 Chilean halictines important for nest architecture studies are corrected, and possible reasons for poor correlation of nest architecture and taxonomy in 3 other Chilean halitzines are discussed.
A NEW SPECIES OF CHRYSOMELOBIA (ACARI: TARSONEMINA; PODAPOLIPIDAE) FROM NORTH AMERICA AND THE TAXONOMIC POSITION OF THE GENUS
- G. C. Eickwort
- BiologyThe Canadian Entomologist
- 1 June 1975
Morphological similarities of all stages of Chrysomelobia with those of the generalized podapolipid Dorsipes support the retention of Chrysamelobia in the PodapolIPidae as a most primitive genus in that family and the only one with 4 pairs of legs in the adult female.
