Conversely, as it is not possible to observe a behavioural manifestation of covert attention, it remains unclear whether covert attentional mechanisms are present to aid target detection by the secondary eyes...

...Elisa Rigosi; Steven D. Wiederman; David C. O'Carroll ABSTRACT An essential biological task for many flying insects is the detection of small, moving targets, such as when pursuing prey or conspecifics. Neural pathways underlying such ‘target-detecting’ behaviours have been investigated...
