Hoverfly responses to looming stimuli depend on elevation and speed

This study shows that hoverflies respond more strongly to looming stimuli approaching from below at intermediate speeds, matching the sensitivity of ventral descending neurons.

Sexual dimorphism in sensorimotor transformation of optic flow

The paper investigates sexual dimorphism in sensorimotor transformation of optic flow in hoverflies, finding dimorphic neural responses but monomorphic behavioral output.

Visual physiology of Australian stingless bees

This study compares the visual physiology of two Australian stingless bee species, finding differences in contrast sensitivity but not spatial resolution.

A new leaf sensing organ in a predatory insect group, the praying mantises (Mantodea)

The paper describes a new sensory organ in praying mantises that detects plant volatiles, supporting their leaf-planking life strategy.

Dual receptive fields underlying target and wide-field motion sensitivity in looming sensitive descending neurons

The paper identifies dual receptive fields in descending neurons of hoverflies that respond to both small targets and looming/widefield stimuli, supporting complex visual behaviors.

Neural responses to reconstructed target pursuits

The paper studies how target-tuned neurons in male hoverflies respond to reconstructed pursuit trajectories, finding that individual neurons respond to specific parts of the pursuit while the population covers a larger proportion.
