As parasitoids upon solitary bees and wasps and their nest cohabitants, Melittobia have an intricate life history that involves both female cooperation and variably expressed male siblicidal conflict. Inter- and intrasexual dimorphism includes blind, flightless males and (probably nutritionally determined) short- and long-winged females. Thought to be highly inbred, Melittobia do not conform to local mate competition (LMC) theory but exhibit simple forms of many social insect traits, including… 
Female Fighting and Host Competition Among Four Sympatric Species of Melittobia (Hymenoptera: Eulophidae)
Melittobia is a genus of parasitic wasps well known for high levels of inbreeding and violent male combat. Casual observations of groups of sisters of M. femorata placed with hosts revealed a
Morphological features, development and reproduction of Melittobia acasta on Bombus terrestris
TLDR
This study shows that both mated and virgin females of M. acasta can produce many offspring on B. terrestris pupae within a short period, indicating that they are dangerous parasites of the bumblebee in a mass rearing system.
INEXPLICABLY FEMALE‐BIASED SEX RATIOS IN MELITTOBIA WASPS
TLDR
The finding that the sex ratios produced by females led to a decrease in their fitness suggests that the existing theory fails to capture a key aspect of the natural history of Melittobia, and emphasizes the importance of examining the fitness consequences of different sex ratio strategies, not only whether observed sex ratios correlate with theoretical predictions.
Solving the sex ratio scandal in Melittobia wasps
TLDR
It is shown that, in nature, females of M. australica have sophisticated sex ratio behaviour, where their strategy also depends upon whether they have dispersed from the patch where they emerged, and whether they should adjust their sex ratio in response to the number of females laying eggs on the patch.
Sex ratios, virginity, and local resource enhancement in a quasisocial parasitoid
TLDR
It is shown that S. harmandi sex ratios are overdispersed, with high variance largely attributable to the common occurrence of developmental mortality, and approaches for the development of LRE theory are suggested, in particular using models of ‘population elasticity’ in which the intensity of kin competition is reduced because extra resources are available to local populations that are more cooperative.
Social evolution in Melittobia
TLDR
It is shown that mating opportunities are sufficiently valuable that male Melittobia will always engage in fighting irrespective of relatedness, that there is no evidence of opponent assessment prior to fighting, and that the intensity of fights increases with the number of competitors.
Nesting and Developmental Biology of the Cleptoparasitic Bee Stelis ater (Anthidiini) and Its Host, Osmia chalybea (Osmiini) (Hymenoptera: Megachilidae)
TLDR
The first account of the nesting biology of Osmia (Helicosmia) chalybea Smith and of its cleptoparasite Stelis (Stelis) ater Mitchell is provided, a newly confirmed host association.
Semiochemical Exploitation of Host-Associated Cues by Seven Melittobia Parasitoid Species: Behavioral and Phylogenetic Implications
TLDR
This study shed light on the host location within the Melittobia genus and represents a first attempt to understand semiochemical use in an evolutionary perspective in the context of parasitoids’ foraging behavior.
Behavioral responses of the parasitoid Melittobia digitata to volatiles emitted by its natural and laboratory hosts
TLDR
It is suggested that M. digitata adopts a ‘sit and wait’ strategy to locate mud dauber wasps, relying mainly on indirect host‐related cues: females search for nests that are under construction and once found, they wait inside the cell until the host completes its cocoon and releases meconium, an indicator that is associated with host suitability.

Female and Male Polymorphism in Two Species of Melittobia Parasitoid Wasps (Hymenoptera: Eulophidae)
TLDR
This study examined the role of maturational factors in 2 widespread representatives of different species groups, M. australica and M. digitata, and concluded that there is no justification for recognizing a “jumper” morph.
On the Life-history of Melittobia acasta , Walker; a Chalcid Parasite of Bees and Wasps
Melittobia is a chalcid, ectoparasitic upon a number of species of Hymenoptera and upon the pupae of certain flies. The insect was bred in the laboratory and the life-history is described in detail.
Review of the Biology of Melittobia acasta (Walker) (Hymenoptera: Eulophidae) and Additions on Development and Sex Ratio of the Species
TLDR
Development, sex ratio, and offspring production, on wild, facultative, and factitious hosts, and size of stages at different temperatures are shown; however, as temperature rises development time decreases.

Temporal patterning of courtship behaviour in some parasitic Hymenoptera, with special reference to Melittobia acasta
TLDR
In Melittobia acasta (Walker) (Eulophidae) the male display is composed not only of repeating elements, but also includes new elements, introduced along the way; the display progresses towards a climactic finale.
Increased male sex ratio among brachypterous progeny in Melittobia femorata, a sib‐mating parasitoid wasp (Hymenoptera: Eulophidae)
TLDR
Melittobia femorata Dahms is unique among the 13 species of Melittobia in that adults emerge as two temporally distinct clutches, and the elevated first clutch sex ratio in this species is discussed.
A Sex Pheromone in Males of Melittobia Australica and M. Femorata (Hymenoptera: Eulophidae)
TLDR
Bioassays implicated the abdomen as the source of the male sex pheromone in both species and forms were strongly attracted to freshly killed mashed and intact males and to living males.
Superparasitism in gregarious hymenopteran parasitoids: ecological, behavioural and physiological perspectives
TLDR
This review synthesizes and interprets the available results in the literature reported from field studies, and from behavioural and physiological investigations, and evaluates superparasitism in gregarious wasps from the host’s angle, addressing host survivorship and development, host food consumption and growth.
