Ever since Modeer (1764) first described maternal egg guarding in the parent bug, Elasmucha grisea, attempts have been made to understand the evolution of postzygotic maternal care in insects (Wheeler 1928; Wilson 1971, 1975; Smith 1980; Zeh & Smith 1985; Tallamy & Wood 1986; Zeh et al. 1989; Clutton-Brock 1991; Tallamy 1994; Trumbo 1996; Tallamy & Schaefer 1997). The task has been difficult, for the disparate appearance of this behaviour throughout 13 orders and at least 45 families of insects… 
Maternal Care, Iteroparity and the Evolution of Social Behavior: A Critique of the Semelparity Hypothesis
Iteroparity was common both among nesting species with non-overlapping broods and in species where a female produces broods of different aged offspring in the same nest (within-nest iteroparity).
Revisiting Paternal Care in the Assassin Bug, Atopozelus pallens (Heteroptera: Reduviidae)
The reproductive behavior of Ralston’s “Zelus” is reexamined in both lab and field to conclude that his descriptions of paternal care were accurate with one important caveat: the authors believe he reversed the sexes.
Facultative Second Oviposition as an Adaptation to Egg Loss in a Semelparous Crab Spider
This work suggests that facultative second oviposition in L. coronatus females has evolved as an adaptation to egg loss, and that the development of ovaries during the guarding period is intrinsically programmed for compensatory Oviposition.
Phenotypic selection and function of reproductive behavior in the subsocial bug Elasmucha putoni (Heteroptera: Acanthosomatidae)
This study is the first to evaluate phenotypic selection on parental care and other reproductive traits in arthropods and showed that early season oviposition and larger clutch size, as well as a longer duration of care by a female, was favored during the breeding episode.
Insights into the costs of complex maternal care behavior in the burrower bug (Sehirus cinctus)
Through analysis of individual maternal performance, there is no evidence for trade-offs between successive clutches, and data suggest that variation in overall condition may obscure variation in allocation strategies.
Parental investment and the evolution of subsocial behaviour in harvestmen (Arachnida Opiliones)
The scarcity of paternal care among harvestmen and the differences when it does occur suggest that male care evolved independently in different laniatorean lineages from a plesiomorphic state of non-care rather than from female care.
Assessing the Semelparity Hypothesis: Egg-guarding and Fecundity in the Malaysian Treehopper Pyrgauchenia tristaniopsis
Finds in field data on reproductive output and maternal care in the Southeast Asian treehopper Pyrgauchenia tristaniopsis are interpreted as being in accordance with the weaker claim of the semelparity hypothesis, i.e. the iteroparous P.tristaniopsis provided less maternal care thanSemelparous membracid species.
Evolution of exclusive paternal care in arthopods.
Comparisons suggest parallels between prezygotic nuptial gifts and exclusive postzyGotic male care and support the hypothesis that, in arthropods, male behaviors that enhance female reproductive success either directly, by releasing females from the fecundity constraints of maternal care, or indirectly, by identifying mates with superior genes (handicap principle), are traits on which sexual selection has acted.
Maternal investment in a spider with suicidal maternal care, Stegodyphus lineatus (Araneae, Eresidae)
The study shows the importance of the female’s body mass and her resource allocation decisions for her reproductive outcome and found that brood size was positively correlated with body mass: larger females had larger broods.
Limited adaptive life-history plasticity in a semelparous
The existence of plasticity in the semelparous spider Stegodyphus lineatus is investigated by drastically reducing brood sizes at different stages of the reproductive cycle and whether females will be able to produce another clutch while caring for young.
