- Visual approach computation in feeding hoverflies
Highlighted Article: Reconstruction of the take-off and flight of feeding female hoverflies when approached by other insects, and quantification of visual parameters, reveals how freely behaving hoverflies perform escape responses from competitors and predators in the wild.
- Photoreceptor signalling is sufficient to explain the detectability threshold of insect aerial pursuers
Summary: Across four insect species, the smallest target size a photoreceptor can robustly encode is sufficient to explain the detection limit of higher-order, target-detecting neurons or observed behavioural pursuits.
