“…Badister pictus is found in the wet grasslands along paddy fields, lakeshores, and riverbanks of Japan, Taiwan, and Russia (Morita 2001;Yahiro 2007;Mori 2018;Anichtchenko et al 2021). Four males and seven females of B. pictus (body length as mean ± standard error: 6.9 ± 0.1; range: 6.5-7.5 mm) were collected using light traps at Sonocho (35°26'53"N, 132°51'58"E, alt.…”

“…For example, adults of the genera Licinus Latreille, 1802 and Diplocheila Brullé, 1834 break snail shells using their extraordinarily asymmetrical mandibles (El-Moursy and Ball 1959;Brandmayr and Zetto Brandmayr 1986;Ball 1992).

The adults and larvae of some groups in the coleopteran family Carabidae are known to prey on snails (Mollusca: Gastropoda). Most species of the carabid tribe Licinini are believed to feed on live snails. However, the snail-eating behavior of only a few species has been studied. Whether adults of the licinine genus Badister can prey on live snails was tested by providing 155 live snails of 20 species (eleven terrestrial and nine aquatic species) to adults of Badister pictus Bates, 1873, and observing their behavior under laboratory conditions. Six of the 20 snail species have an operculum that can close the aperture of the shell. Each B. pictus adult attacked all of the snails provided. Badister pictus successfully preyed on ten terrestrial and six aquatic snail species. These beetles used their strikingly asymmetrical mandibles to break the dextral shells along the dorsal part of the whorls from the outer lip of the aperture towards the apex, allowing subsequent consumption of the soft bodies. However, 41.9% of snails could not be eaten by B. pictus adults. The rate of predation success by B. pictus decreased with increasing shell size and thickness of snails. In addition, the presence of an operculum decreased the rate of predation success by B. pictus. The results show that the shell size, thickness, and operculum of some snail species could play important roles in preventing B. pictus mandibles from breaking the shells. Therefore, Badister beetles may exert selective pressure on the evolution of defensive shell structures in small-sized snails.

“…Adults of the beetle tribe Brachinini Bonelli (Coleoptera: Carabidae) can eject toxic chemicals at temperatures of approximately 100 C (i.e., bombing) from the tips of their abdomens in response to a predator attack (Aneshansley et al, 1969;Dean, 1979;Eisner, 2003;Eisner, Eisner & Siegler, 2005;Arndt et al, 2015). Beetles of the subfamily Brachininae Bonelli, which comprises the tribes Brachinini (645 species in 8 genera) and Crepidogastrini Basilewsky (123 species in 6 genera), are called 'bombardier beetles' (Arndt, Beutel & Will, 2016;Anichtchenko et al, 2021). Bombardier beetles of the tribe Brachinini store hydroquinone and hydrogen peroxide separately in two reservoirs in the abdomen (Eisner, 2003).…”

Beetle bombing always deters praying mantises

Some animals have evolved chemical weapons to deter predators. Bombardier beetles (Coleoptera: Carabidae: Brachininae: Brachinini) can eject toxic chemicals at temperatures of 100 °C from the tips of their abdomens, ‘bombing’ the attackers. Although some bombardier beetles can reportedly deter predators, few studies have tested whether bombing is essential for successful defence. Praying mantises (Mantodea) are ambush predators that attack various arthropods. However, it is unclear whether bombardier beetles deter mantises. To test the defensive function of bombing against praying mantises, I observed three mantis species, Tenodera sinensis, Tenodera angustipennis, and Hierodula patellifera (Mantidae), attacking the bombardier beetle Pheropsophus jessoensis (Carabidae: Brachininae: Brachinini) under laboratory conditions. All mantises easily caught the beetles using their raptorial forelegs, but released them immediately after being bombed. All of the counterattacked mantises were observed to groom the body parts sprayed with hot chemicals after releasing the beetles. When treated P. jessoensis that were unable to eject hot chemicals were provided, all mantises successfully caught and devoured the treated beetles. Therefore, bombing is essential for the successful defence of P. jessoensis against praying mantises. Consequently, P. jessoensis can always deter mantises.
