Behavioural responses to radio‐tag attachment in butterflies: Evidence for active tag removal

Ecological Entomology, EarlyView.
During controlled indoor flight experiments with 89 butterflies from eight tropical species, we monitored behavioural responses to dorsally attached radio tags using high‐speed video recordings. Four of 39 Morpho helenor exhibited coordinated abdominal flexion and hind leg movements directed toward the tag antenna during flight; in two individuals this

No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

Ecological Entomology, EarlyView.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

Ibis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Floral resource strips enhance parasitoid abundance and diversity in apple orchards and promote agroecological advances in a South African biosphere reserve

Insect Conservation and Diversity, EarlyView.
Floral resource strips within apple orchards increased parasitoid abundance and influenced community composition, enhancing local biodiversity in the Kogelberg Biosphere Reserve's transition zone. Ruderal and natural fynbos habitats supported higher parasitoid richness and abundance, emphasising the importance of conserving semi‐natural habitats ...

Forest type influence on Heliconia‐dipteran interaction networks

Insect Conservation and Diversity, EarlyView.
Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.

Wild bee diversity and land use: A case study in a mountain agroecosystem of the Serranía de Ronda, southern Spain

Insect Conservation and Diversity, EarlyView.
Orchards supported the highest wild bee diversity and functional diversity, highlighting their role in maintaining bee communities in Mediterranean agroecosystems. Landscape heterogeneity positively influenced functional evenness and dispersion of wild bee communities, underscoring the importance of diverse landscapes for bee conservation. The presence
