SummarySeveral years' observations of population of a primitively social halictine bee,Halictus rubicundus, revealed the following: (1) there is a correlation between ambient temperatures during the spring provisioning phase and the sex ratio of the resulting brood, such that warmer temperatures are associated with an increase in male bias; (2) over the course of the season, the degree of male bias of eggs laid appears to correspond with photoperiod; and (3) increasing male bias in the first… 

Social polymorphism and social behaviour in sweat bees (Hymenoptera: Halictidae)

It is shown that queens probably incurs costs from producing more workers, and that a possible mechanism is that workers from larger groups may be of lower quality, and the mechanisms underlying social polymorphism and body size in this species are investigated.

Colony social organization of Lasioglossum malachurum Kirby (Hymenoptera, Halictidae) in southern Greece

Nesting and social biology of two aggregations of the obligately eusocial halictine bee Lasioglossum malachurum at Agios Nikolaos Monemvasias (ANM) in southern Greece revealed social and demographic variation between aggregations and years, as well as notable differences between these and other European populations.

Social polymorphism in the sweat bee Lasioglossum (Evylaeus) calceatum

This research determined the social phenotype of Lasioglossum calceatum, a widespread sweat bee that is thought to be socially polymorphic, and investigated sociality in detail across two years at the southernmost site, finding that it exhibits latitudinal social polymorphism within the UK.

Degree-day accumulation controlling allopatric and sympatric variations in the sociality of sweat bees, Lasioglossum (Evylaeus) baleicum (Hymenoptera: Halictidae)

The effect of degree-day accumulation on the sympatric social variation of L. baleicum was examined by rearing the bees to calculate the threshold temperature and the estimated dates were always consistent with observed eclosion dates.

Sex ratio variations among years and breeding systems in a facultatively parthenogenetic termite

Estimating colonial and population sex ratio over two consecutive dispersal periods in a French Guiana population of Cavitermes tuberosus in which the founding queen may be replaced only after colony maturity, some neotenic females may be sexually produced, and some female dispersers arise through parthenogenesis confirms that AQS breeding system is not necessarily linked with female-biased sex ratio.

Consequences of a warming climate for social organisation in sweat bees

Detailed foraging data is analysed in relation to climate change predictions for Great Britain to show that worker numbers and sociality both increase under predicted climate change scenarios, and that sociality should appear in northern areas where it has never before been observed.

Subsociality in halictine bees

It is suggested that seventeen species of eusocial halictine bees provide parental care, i.e. are subsocial, which suggests that in transitions to eUSociality, brood care antedated eussociality.

Fitness consequences of ecological constraints and implications for the evolution of sociality in an incipiently social bee

It is suggested that social nesting represents a form of bet-hedging against unpredictable fluctuations in parasite number in the socially polymorphic small carpenter bee, Ceratina australensis, based on 982 nests collected over four reproductive periods.

Environmental barriers to sociality in an obligate eusocial sweat bee

It is shown that transplanted bees can exhibit eusociality, but that the short length of the season and harsher environmental conditions could preclude its successful expression, and suggests that short season length together with poor weather conditions represent an environmental barrier to the evolution and expression of eussociality in sweat bees.

Genetic differentiation across the social transition in a socially polymorphic sweat bee, Halictus rubicundus

Results from conceptually different analyses consistently showed greater genetic differentiation between geographically distant populations, independently of their social phenotype, suggesting that the two social forms are not reproductively isolated.




E. nigripes is a large, polylectic social halictine bee, common in the Mediterranean region, which has a relatively distinct morphs, although caste determination can be influenced by environmental factors.

Observations of inter- and intraseasonal dispersal patterns in the primitively social sweat bee Halictus rubicundus in New York reveal considerable philopatry in both sexes, which should have important effects on population structure, particularly in terms of population subdivision, mate choice, and intracolony interactions.

The social organisation of Halictus ligatus (Hymenoptera; Halictidae) in southern Ontario

The social organisation of Halictus ligatus was studied at Victoria, southern Ontario. At this locality, the one worker brood has a protracted period of emergence; this results in small colony

Analysis of possible mechanisms of caste determination reveals that although gynes average significantly larger than non-gynes within the first brood, this appears largely due to a late mean emergence data coupled with an increase in the size of emerging females over the course of brood emergence, rather than a causal relationship.

Many of the females of the first summer brood of the sweat bee Halictus rubicundus mate, soon vanish from the nesting site, undergo diapause, and return unworn the following spring to found their own

Partial bivoltinism may cause alternating sex-ratio biases that favour eusociality

A model for the evolution of sex ratios in species having two generations per year with an asymmetrical pattern of overlap between the generations is described, showing one particular way in which ecological and genetic variables may interact to encourage the emergence of eusociality in some species and to discourage it in others.

The Nova Scotia population of Augochlorella striata had i) a lower proportion of multiple foundress nests, ii) a smaller worker brood and iii) a briefer period of foraging activity but iv) comparable overall nest productivity.
