Faunistic survey of myrmecophilous and other ant-associated beetles and spiders in the Belgian province of Limburg (Araneae, Coleoptera, Hymenoptera: Formicidae)
- Many researchers have been fascinated by the social organisation within an ant colony. They have noticed that several other invertebrates are found in or near the ants’ nests, notably a variety of Coleoptera and to a lesser extent, some spiders. Many of these observations have been written down, some just as a brief statement but sometimes a detailed report of these interactions as a result of accurate and prolonged monitoring was published. All this information allowed us to make a comparison with the ant species associated with beetles and spiders in the Belgian province of Limburg. We will discuss a large number of species within their respective families and mention in particular a certain connection between the guest and its host, a relationship which cannot necessarily be called myrmecophilous

Remarks on Hymenoptera on urban green roofs in Belgium
- In this paper we discuss all Hymenoptera (10.085 specimens) caught on several urban green roofs in Belgium during 2020 and 2021. We thereby try to connect species’ ecology and the specific habitat of extensive green roofs. Based on these findings we suggest what life communities can indeed be expected there. Six species on 120 taxa discovered are first reported for Belgium: Gonatopus lunatus (var. bifasciatus) Klug, 1810 (Aculeata: Dryinidae); Synacra paupera Macek, 1995 (Parasitica: Diapriidae); Alysia lucicola Haliday, 1838, Idiasta dichrocera Konigsmann, 1960 and Leiophron deficiens (Ruthe, 1856) (Parasitica: Braconidae) and Gelis declivis Forster, 1850 (Parasitica: Ichneumonidae).

De loopkever Amara strenua en zijn recente uitbreiding in Nederland en België (Coleoptera: Carabidae)
- Na lange tijd niet te zijn waargenomen, lijkt de loopkever Amara strenua weer in toenemende mate voor te komen in Nederland en België. Voor ons was dat een unieke gelegenheid om meer te weten te komen over deze internationaal schaarse soort. We hebben gekeken naar de verspreiding van A. strenua, de karakteristieken van zijn habitat en naar zijn biologie. Door middel van kweekproeven kon voor het eerst de larve (stadium II) beschreven worden. Ten slotte beschrijven we een nieuw kenmerk om A. strenua van A. kulti te onderscheiden.

La pratique de l’entomologie du terrain au conservatoire ou l’essentiel est de bien transmettre
- The principles and conventions concerning research, killing, treatment, preparation and classification of insects in collections are discussed in this note. A special attention to the labeling and related items are recalled with the aim of harmonizing practices and correcting drifts observed over the time.

Hypoponera eduardi (Forel, 1894) (Hymenoptera: Formicidae) on extensive green roofs in the Province of Antwerp: a new species for the Belgian ant fauna
- From 2019 until 2021, we investigated extensive green roofs in Flanders (Belgium) for their arthropod communities. On two different roofs we found, amongst the collected specimens, a species new for the Belgian ant fauna: Hypoponera eduardi (Forel, 1894). The presence of multiple worker ants belonging to this species indicates that it has formed a colony on at least one roof. Apparently, the warm and dry conditions that arise on extensive green roofs as a consequence of the shallow substrate layers lead to suitable habitat conditions for this species.

Notes on the myrmecophilous spider Mastigusa arietina (Thorell, 1871)
- We provide records of the rarely detected ant-associated spider Mastigusa arietina (Thorell, 1871) in northwest Belgium and discuss how to locate and capture this spider. We show that this myrmecophilous spider is much more common than currently presumed but it is often missed in common spider surveys due to its obligate association with ant nests. We also summarise and illustrate the recently gained insights into its ecology, behaviour, and interactions with its host and other ant associates.

IUCN's encounter with 007: safeguarding consensus for conservation
- A controversy at the 2016 IUCN World Conservation Congress on the topic of closing domestic ivory markets (the 007, or so-called James Bond, motion) has given rise to a debate on IUCN's value proposition. A cross-section of authors who are engaged in IUCN but not employed by the organization, and with diverse perspectives and opinions, here argue for the importance of safeguarding and strengthening the unique technical and convening roles of IUCN, providing examples of what has and has not worked. Recommendations for protecting and enhancing IUCN's contribution to global conservation debates and policy formulation are given.
