Lords of the flies: dipteran migrants are diverse, abundant and ecologically important

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1635-1659, August 2025.
ABSTRACT Insect migrants are hugely abundant, with recent studies identifying the megadiverse order Diptera as the major component of many migratory assemblages. Despite this, their migratory behaviour has been widely overlooked in favour of more ‘charismatic’ migrant insects such as butterflies, dragonflies, and moths.

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Finite-size scaling as a way to probe near-criticality in natural swarms [PDF]

open access: yes, 2014
Collective behaviour in biological systems is often accompanied by strong correlations. The question has therefore arisen of whether correlation is amplified by the vicinity to some critical point in the parameters space.

Tree hollow parameters and their effects on saproxylic arthropod diversity: A multi‐taxon approach

open access: yesInsect Conservation and Diversity, Volume 18, Issue 4, Page 580-592, July 2025.
Tree hollows are keystone structures for biodiversity in forests and support saproxylic arthropods but are declining in central Europe due to intensive forest management, threatening these invertebrate communities. Research using DNA metabarcoding examined non‐beetle arthropods in 40 beech tree hollows, exploring their habitat requirements in southern ...

Rocksitter Flies (Lauxaniidae: Cestrotus) are Key‐Pollinators of Ceropegia pulchellior—A Threatened and Localised South African Endemic With Foetid‐Scented Flowers

open access: yesJournal of Applied Entomology, Volume 149, Issue 6, Page 888-900, July 2025.
ABSTRACT Short‐tongued saprophilous flies are a diverse but under‐appreciated group of pollinators, which are particularly important for flowers in the subtribe Stapeliinae (Apocynaceae‐Asclepiadoideae‐Ceropegieae). This clade of plants is characterised by repeated shifts between tubular kettle‐trap and open non‐trap flowers and chemical mimicry (of ...
