Article Reference 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.

Article Reference 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.

Article Reference 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.

Article Reference 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).

Article Reference 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

Article Reference Do carabids struggle to recolonize restored grasslands in the fragmented landscapes of Northern Belgium?
1. Semi-natural grasslands in Western Europe are degrading and declining. Their plant species diversity and associated fauna, such as arthropods, are decreasing fast making restoration crucial. 2. Carabid beetles are an essential link in ecosystem functioning (e.g., through herbivory and predation) and provide important ecosystem services (e.g., pest control). As a diverse group from different trophic levels, they occupy a variety of ecological niches, making them good indicators of restoration success and habitat quality. 3. To study how different aspects of carabid diversity change along a restoration gradient from degraded grasslands to restored semi-natural Nardus grasslands, we sampled carabid beetles in grasslands in Northern Belgium. We analysed differences in abundance, diversity and community composition and investigated carabid traits potentially influencing carabids’ response to grassland restoration. 4. Species richness did not change along the restoration gradient, but number of individuals decreased as grassland restoration time and effort increased and species composition changed, mostly caused by species turnover. As grassland restoration time and effort increased, carabid body size decreased and the proportion of dayactive carabids increased. Predators and habitat generalists were dominant along the entire gradient. 5. Even though the target vegetation was restored, the carabid communities were not, or at least, did not possess yet traits to be expected from a restored community. The landscape in Northern Belgium might be too fragmented for larger species with low dispersal ability to recolonize restored grasslands. However, restored speciesrich grasslands are beneficial for conservation of meadow birds as day-active beetles thriving in restored grasslands are an important food source
