Antipredator benefits of group living in colonial web-building spiders: the ‘early warning’ effect
Analysis of naturally occurring wasp attack ‘runs’ showed that the per-attack run and per-spider capture success of wasps decreased significantly with increased spider colony size, and the ‘early warning’ hypothesis of antipredator benefits for colonial web-building spiders was supported.

Seroepidemiological data indicate that ERBV2 infection of horses may be common (24%) in Australia, and it is suggested that P313/75 can be classified as a new serotype of the genus Erbovirus, tentatively named ERbV2.

SummaryIn the laboratory, females of Gerris remigis foraging singly after being separated from a copulating male averaged 16 times longer to repel male copulatory attempts compared to repelling time…

Sex Discrimination in Gerris remigis: Role of a Surface Wave Signal
- R. Wilcox
- 14 December 1979
Freely moving females that were artificially made to play back computer-generated male surface wave and body-contact signals were treated as males by the masked males and as females when no such playbacks were made.
Ripple communication in aquatic and semiaquatic insects

Abstract:Among insects, ripple communication has been described in water striders (Gerridae) and giant water bugs (Belostomatidae), although it also seems likely to occur in whirligig beetles…
Spider flexibly chooses aggressive mimicry signals for different prey by trial and error
Evidence is provided that Portia uses a trial-and-error method as part of its strategy for deriving appropriate signals for different prey, and appears to be an example of deception involving at least a limited form of learning in invertebrates.
Observations in nature of detouring behaviour by Portia fimbriata, a web‐invading aggressive mimic jumping spider from Queensland
These detours of Portia fimbriata were longer and more complex than those previously recorded for salticids, and these are the first detailed records of detouring behaviour by a salticid in the field.
Aggressive mating as a tragedy of the commons in the water strider Aquarius remigis

It is shown in a laboratory study that competition among males for females can also result in a tragedy of the commons’ situation, and individual differences in male aggression are stable across time and are not influenced by food or light regime, although all individuals become nonaggressive in the presence of fish predators.
