“…In taxa that exhibit defaecation or even AH in conjunction with DF (e.g. some lizards, most snake species, some Coleoptera) [21][22][23], interactions among these behaviours can become more apparent with future studies. Moreover, our findings provide evidence for the functional integration of distinct antipredator behaviours across sequential phases of the predator-prey interaction (musking during the capture phase and DF and AH during the post-capture phase).…”

“…The fact that DF occurs widely across various taxa suggests its effectiveness (insects [11]; fish [12,13]; amphibians [14,15]; reptiles [16,17]; birds [18,19]; mammals [20]), yet the precise mechanism by which DF enhances survival remains unclear. The presentation of this risky antipredator behaviour is rather distinctive across various taxa, often involving defaecation and autohaemorrhaging (AH) as common components in this display [21][22][23]. Still, when considering the extensive variation in DF displays, perhaps the most elaborate displays are seen in different snake species, such as Tropidophis sp.…”

Predation exerts a significant selection pressure on prey, shaping a multitude of traits that serve as antipredator defences. In turn, natural selection could favour combinations of antipredator defences with synergistic effects that enhance prey survival. An especially interesting antipredator defence is death feigning (DF), present in a wide variety of taxa and usually characterized by the prey lying motionless often along with defaecation, musking and autohaemorrhaging (AH). All these aspects of the DF display should work in conjunction with one another, intensifying the overall effect of the display and in turn facilitating quicker escape. To confirm this hypothesis, we tested 263 dice snakes ( Natrix tessellata ) directly in the field. We noted the occurrence of smearing faeces, musk and AH, and we measured the duration of DF, expecting to see a negative association between the occurrence of these behaviours and the duration of DF. Our results affirm our hypothesis: dice snakes that smeared themselves in musk and faeces prior to DF and had AH during DF spent significantly less time in DF. Our results highlight the functional integration of antipredator behaviours across different phases of predator–prey interactions, emphasizing the need for future research to prioritize studying the sequential display of behaviours.

“…Species of the family Meloidae, commonly known as blister beetles, present a wide range of complex courtship and defensive behaviors (Selander 1964(Selander , 1965Pinto 1972Pinto , 1977Rosas-Ramos et al 2021). Courtship behavior has been found to be particularly diverse in the tribe Eupomphini (Pinto 1975(Pinto , 1977(Pinto , 1984Selander 1964)…”

“…One of the most striking cases is probably related to epigean oil-beetles. Within meloids, these species are the largest among the clade — up to 5–7 cm total length — and present a very rich defensive behaviour repertoire (Bologna 1991, Rosas-Ramos et al 2021, Cortés-Fossati 2022a,b) — highlighting the autohaemorrhage — reinforced by a highly aposematic pattern — always presumed, never tested — in some species (Bologna 1991). In the Old World, records of shrikes preying on epigean oil-beetles have been published since the 19th century.…”

When Toxicity is Not Enough: Review and New Data on Blister Beetle (Coleoptera, Meloidae) Predation by Shrikes

Shrikes from the genus Lanius are generalists in terms of diet, even consuming highly toxic species, as blister beetles (Coleoptera, Meloidae). Despite the fact that regular predation on these coleopterans have never been described both in recent and historical literature, birds stand out as one of the groups to most often prey upon these insects. In the Old World, records of shrikes preying on oil-beetles -most of them treated as anecdotal -have been published since the 19th century. However, despite being repetitive, no review or in-depth study of this behavior has been conducted. After a literature study and new data collected in the Iberian Peninsula, it seems an extended behaviour within the clade. As could be observed in a high number of cases, birds even apply a specific technique, selecting specific body parts to kill the beetle, more sclerotic and presumably less toxic. In some cases, strict predation has been demonstrated. To date, at least six different shrike species -Red-backed Shrike Lanius collurio, Great Grey Shrike L. excubitor, Iberian Grey Shrike L. meridionalis, Loggerhead Shrike L. ludovicianus, Lesser Grey Shrike L. minor, and Woodchat Shrike L. senator -have been found to show signs of preying on at least nine Meloidae species throughout Europe, North Africa and North America, constituting a line of research that should be studied in greater detail.
