The broad objectives of the International Heteropterists’ Society (IHS) are to promote systematic, biogeographic, and biological studies of Heteroptera and to cultivate cooperative research among heteropterists throughout the world. The Society is organized and operated exclusively for scientific and educational purposes.

The Society holds a meeting every four years at locations around the world, where members give presentations on their work and discuss the directions of the Society. The Society’s website provides an online portal for distribution of information about bugs, including a world bibliography, taxon pages, and membership details.

Interested in joining the IHS? Read more about the Society and information on membership. You can also donate to the Student Travel Fund your contribution is very valuable!

We had an excellent presentation about the next Meeting in Thailand during the last Truebug Tuesday.

Follow the link to our Youtube channel to see it, and do not forget to explore the section about the Meeting. If you have any questions, contact the organizer Bob Sites (bugsinbangkok@gmail.com).

Nowińska A. & Kóbor P.: "Morphological study using both light and scanning electron microscopy reveals systematic and ecological importance of antennal morphology in big‑eyed bugs (Hemiptera: Heteroptera: Geocoridae)".

Insects’ sensory organs (sensilla) are important structures responsible for reception of environmental stimuli, a majority of which are present on the antennae. The aim of this study was to analyze morphological types of antennal sensilla in selected species of big-eyed bugs (Geocoridae) to assess their relation to the systematics and ecology of the taxon. Main types of mechano-, chemo-, and thermo-hygroreceptive sensilla were observed in all the studied species. However, differences in the distribution patterns of sensilla were observed between two studied subfamilies. The study also revealed a cavity on distiflagellomere supporting the monophyly of the family. Its development and types of sensilla present might correspond to different ecological adaptations. More studies are needed to ultimately confirm this hypothesis.

Chen Z. et al.: "Tool use aids prey-fishing in a specialist predator of stingless bees".

Tool use is widely reported across a broad range of the animal kingdom, yet comprehensive empirical tests of its function and evolutionary drivers remain scarce, predominantly focused on a few relatively intelligent vertebrate lineages. In this study, we provide a comprehensive examination of tool use behavior in the assassin bug Pahabengkakia piliceps, a specialist predator of stingless bees that exploits resin droplet from bee nest entrance to facilitate hunting. Field behavioral experiments demonstrated that resin use is critical for hunting success, as the predator uses resin to stimulate the colonial defense of stingless bees, luring attacking bees toward its optimal hunting position. Chemical analysis revealed that resin processing by the assassin bug enhances the emission of volatile compounds, making the resin more attractive and stimulating to guard bees. Through these experiments, we empirically demonstrate how an invertebrate predator adapts to the colony defense of social insects via tool use behavior. We further propose that complex tool use can evolve under selective pressures driven by diet specialization. Our findings offer a new model for studying the adaptive functions and underlying mechanisms of tool use behaviors in animals..

Kim W. et al.: "Additions, corrections, and bibliographic issues on the Heteropteran fauna of Korea (Insecta: Hemiptera)".

We address issues of faunistic studies on Korean true bugs (Hemiptera: Heteroptera) and critically review the literature records on recently (2011–2024) reported species. Furthermore, 18 species in 11 families are newly reported from Korea: Cimicomorpha—Anthocoridae: Elatophilus (Elatophilus) nipponensis Hiura, 1966, Temnostethus (Temnostethus) gracilis Horváth, 1907; Miridae: Stethoconus takaii Nakatani & Yasunaga, 2018, Yamatofulvius miyamotoi Yasunaga, 2000; Reduviidae: Oncocephalus heissi Ishikawa, Cai & Tomokuni, 2006, Polytoxus fuscovittatus (Stål, 1860); Tingidae: Physatocheila nigrintegerrima Souma, 2019; Pentatomomorpha—Aradidae: Aradus unicolor Kiritshenko, 1913, Aneurus (Aneurodes) taterasanus Shimamoto & Ishikawa, 2022, Neuroctenus quercicola Nagashima & Shono, 2003, Mezira pygmaea Hsiao, 1964; Cydnidae: Parachilocoris japonicus Lis, 1994; Lygaeidae: Arocatus rufipes Stål, 1872; Pachygronthidae: Pachygrontha similis Uhler, 1896; Pentatomidae: Niphe elongata (Dallas, 1851); Pyrrhocoridae: Dysdercus (Paradysdercus) evanescens Distant, 1902; Rhyparochromidae: Appolonius oblongus Tomokuni, 1995, Neolethaeus lewisi (Distant, 1883), of which five species are recorded based on photographic evidence. Eleven species are excluded from the Korean fauna based on review of literature records: Acanthosomatidae: Elasmucha signoreti Scott, 1874, Lindbergicoris gramineus (Distant, 1883); Aradidae: Brachyrhynchus taiwanicus (Kormilev, 1957), Daulocoris formosanus Kormilev, 1971, Mezira subtilis Josifov & Kerzhner, 1974; Miridae: Apolygus nigrovirens (Kerzhner, 1988), Neolygus lobatus (Linnavuori, 1963), Kasumiphylus ryukyuensis (Yasunaga, 1999), Tytthus parviceps (Reuter, 1890); Pentatomidae: Erthesina fullo (Thunberg, 1783), Plautia splendens Distant, 1900. Three species are reconfirmed from Korea: Geocoridae: Geocoris (Geocoris) proteus Distant, 1883; Rhyparochromidae: Caridops pseudadmistus Zheng, 1981; Veliidae: Halovelia septentrionalis Esaki, 1926.
