Abstract. 1. Reproductive interference occurs when members of different species engage in reproductive interactions, leading to a fitness cost to one or both actors.2. These interactions can arise through signal interference ('signal-jamming'), disrupted mate searching, heterospecific rivalry, mate choice errors, or misplaced courtship, mating attempts or copulation.3. We present a definition of reproductive interference (RI) and discuss the extent to which a failure of species discrimination is central to a definition of RI.4. The possible mechanisms of RI are reviewed, using a range of insect examples. 5. Some of the causes and consequences of RI are discussed, focusing in particular on mating systems and mating system evolution.6. We conclude by considering future ways forward, highlighting the opportunities for new theory and tests of the old theory presented by reproductive interference.

“…As M. caffra females show high levels of sexual cannibalism, such attempts frequently end in the male's death ( Fig. 3; Fea et al, 2013). Extreme costs need not only arise from damage or predation though.…”

“…However, for male Habronattus , indiscriminate courtship comes with a risk that is not faced by males in many other taxa: female aggression and predation. While this phenomenon has not been well-studied, there is recent evidence from two taxa of voracious predators (praying mantises and gift-giving spiders) that indiscriminate courtship by males leads to aggression and predation by heterospecific females [12–13]. Our data show that female aggression in Habronattus can occur during both conspecific and heterospecific courtship in the field.…”

“…Even conspecific courtship is risky; if heterospecific courtship never results in offspring, we might expect strong selection on males to avoid it. Despite a growing body of literature addressing misdirected courtship in animals, few studies have considered the potential cost of predation from the female that is being courted (see [9] for a review of misdirected courtship); this cost is unique to voracious and cannibalistic predators such as spiders [12] and praying mantises [13]. …”

Frequent misdirected courtship in a natural community of colorful Habronattus jumping spiders

Male courtship display is common in many animals; in some cases, males engage in courtship indiscriminately, spending significant time and energy courting heterospecifics with whom they have no chance of mating or producing viable offspring. Due to high costs and few if any benefits, we might expect mechanisms to evolve to reduce such misdirected courtship (or ‘reproductive interference’). In Habronattus jumping spiders, males frequently court heterospecifics with whom they do not mate or hybridize; females are larger and are voracious predators, posing a severe risk to males who court indiscriminately. In this study, we examined patterns of misdirected courtship in a natural community of four sympatric Habronattus species (H. clypeatus, H. hallani, H. hirsutus, and H. pyrrithrix). We used direct field observations to weigh support for two hypotheses (differential microhabitat use and species recognition signaling) to explain how these species reduce the costs associated with misdirected courtship. We show that, while the four species of Habronattus do show some differences in microhabitat use, all four species still overlap substantially, and in three of the four species individuals equally encountered heterospecifics and conspecifics. Males courted females at every opportunity, regardless of species, and in some cases, this led to aggression and predation by the female. These results suggest that, while differences in microhabitat use might reduce misdirected courtship to some extent, co-existence of these four species may be possible due to complex communication (i.e. species-specific elements of a male’s courtship display). This study is the first to examine misdirected courtship in jumping spiders. Studies of misdirected courtship and its consequences in the field are limited and may broaden our understanding of how biodiversity is maintained within a community.

“…Furthermore, the introduced M. caffra in New Zealand has proven its interaction with O. novaezelandiae goes beyond pure competition. It has been shown that by sexual deceit, M. caffra females will attract males of the native species willing to mate (Fea et al 2013). The latter are then eaten and mating is not accomplished.…”

The Afrotropical Miomantis caffra Saussure 1871 and M. paykullii Stal 1871: first records of alien mantid species in Portugal and Europe, with an updated checklist of Mantodea in Portugal (Insecta: Mantodea)

The recent growing interest on the Mantodea fauna of southern Europe and Portugal in particular, has enabled the discovery of two geographically separated populations of hitherto unknown species in Europe. Analysis of specimens shows that they belong to two Afrotropical mantids: Miomantis caffra Saussure, 1871 and Miomantis paykullii Stal, 1871, thus raising the number of known species in Europe to 39 and in Portugal to 11.While these are remarkable findings, they also represent the first alien mantis species recorded from this continent. As yet, these species appear to be confined to artificial humanised gardened areas but call for more attention to the problem of biological invasions and the need for better bio-security measures for the conservation of natural ecosystems.In the absence of recent revisionary work on the Mantodea of Portugal and given the need to provide an accessible identification tool, both a checklist and a key to species are provided for all species in the country.
