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

open access: yesEcological 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

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

open access: yesInsect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Non‐crop habitats and cover crops as potential ecological corridors and stepping stones for autumnal migrating hoverflies

open access: yesInsect Conservation and Diversity, EarlyView.
Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

open access: yesInsect Molecular Biology, EarlyView.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.
