UV‐Induced Fluorescence in the Balance: Mate Choice and Predation Risk in the Female Ornamented Jumping Spiders

open access: yesIntegrative Zoology, EarlyView.
This study investigates the potential adaptive advantages of female‐specific UV‐induced fluorescence in male mate‐choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. Our findings provide empirical evidence of a trade‐off: While fluorescence enhances male mate preference, it ...

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

State of the spread of the exotic parasitoid wasp Leptopilina japonica tracking the route of its invasive host fly Drosophila suzukii in France

open access: yesAgricultural and Forest Entomology, EarlyView.
To document the current distribution of Leptopilina japonica in France and compare its genetic background, we collected wild fleshy‐fruited plants and cultivated cherries from 11 sites across different regions. The fruits were collected from the canopy. We calculated the percentage of emerging individuals of L.
