“…These cues might be intraspecific chemical odours, which have direct or indirect genetic foundations (Roberts et al, 2003). Chemically mediated kin recognition is reported in spiders (Miller, 1989;Evans, 1999). Cannibalism did not occur more or less frequently when the larvae were fed the same diet compared to different diets, suggesting that diet has no role as an exogenous cue for detecting kinship.…”

Abstract. The role of relatedness and diet in kin recognition was investigated in the aphidophagous ladybirds Propylea dissecta and Coccinella transversalis. Third instar larvae of both species exhibited kin recognition, as they were reluctant to consume related first instar larvae. They spent significantly more time prior to cannibalism when interacting with genetically related victims; this indicates the presence of a kin recognition system. Kin recognition, however, was not evident in fourth instar larvae as they ate both related and unrelated victims. This result reveals that the need of fourth instar larvae to attain a critical weight for pupation might subdue kin recognition. The diet of cannibals did not affect cannibalism, number of encounters or time that elapsed prior to cannibalism. This indicates that kin recognition is not dependent on exogenous cues derived from the diets of the cannibal and victim.

“…As many taxonomic groups have not been studied (Table 7.1), general conclusions about the occurrence and adaptive significance of kin recognition cannot be drawn. However, based on the present data its benefits seem to be unequally distributed across the taxon and often not easy to reveal (Evans 1999). It is important to note that the apparent lack of kin discrimination does not necessarily imply that this trait is absent; it may simply not be in use in relation to the behaviours under investigation.…”

“…In the thomisid subsocial spider Diaea ergandros, Evans (1999) showed that the performance of sibling groups does not significantly differ from groups of unrelated individuals in the adult stage. Juveniles, however, contribute more to nest construction when cooperating with siblings, and if unfavourable conditions causes the colony to starve, cannibalism spreads and spiders then prefer to eat non-sibs first (Evans 1999).…”

Social Recognition in Invertebrates

More than 99 % of arachnid species are solitary, aggressive and often cannibalistic predators. A few species are social and cooperative, but they do not reach the level of eusociality found in some insects. Kin recognition is suggested to be a key feature for the evolution of cooperation and sociality and thus found predominantly in those few species. While kin recognition and social interactions are well investigated in spiders, these behaviours are understudied in other arachnid taxa. Nevertheless, social species are also known in the Acari, Pseudoscorpiones, Scorpiones, Opiliones and Amblypygi. Still, we have limited information on the adaptive value of social recognition in arachnids, how it is facilitated and maintained. While this field of research is still young, it has produced some encouraging results. This chapter reviews the knowns and the unknowns of social recognition mechanisms with respect to their importance for the evolution of arachnid sociality. We will particularly focus on kin recognition and kin discrimination. First, we shortly introduce the evolution of sociality in arachnids which provides the background for the understanding of the different recognition and discrimination mechanisms explained subsequently. Further, we illustrate the interspecific discrimination abilities of arachnids, and present the state of the art on intraspecific recognition and kin recognition in spiders and other arachnids. This chapter illustrates that various social recognition abilities and especially kin recognition exist in social but also non-social arachnids. These mechanisms allow different species to distinguish between familiar and foreign, or related and unrelated individuals, to either support or discriminate against them. In contrast to eusocial insects, the necessity of maintaining kin recognition abilities often appears to be obscure and highly context-dependent. Thus, a generalisation of its adaptive value in arachnids is not possible. There is some evidence for the concept of kin recognition facilitating the evolutionary transition from subsocial

“…The filial cannibalism and nest mate recognition in F. binodulus resembles that in social spiders in which sociality is associated with a family group and extended maternal care. Although unrelated spiders are accepted by a group, cannibalism and some kin recognition occurs (Evans, 1999). In addition, communal breeding is often profitable even if group members are not kin.…”

Sociality improves larval growth in the stag beetle Figulus binodulus (Coleoptera: Lucanidae)

Abstract. The benefits for offspring of attendant adult were investigated in the stag beetle Figulus binodulus. The initial growth rate of third-instar larva was significantly higher when the larvae were in a nest with adults compared to those in a nest without adults. The difference in growth rate is reflected in adult body size. Although the presence of adult beetle generally benefited the offspring, the adults did eat some of the larvae. Filial cannibalism was the primary cause of juvenile death in nests with adults. Mortality was lower in nests with adults related to the juveniles compared to nests with unrelated adults, suggesting that infanticide of nest mates may be inhibited. These results suggest that F. binodulus has a level of sociality and nest mate recognition that is very rare in stag beetles. Social behaviour may be more advantageous for small stag beetles than fighting.
