Spatial memory helps animals to navigate familiar environments. In insects, spatial has extensively been studied in central place foragers such as ants and bees. However, if butterflies memorize a location remains unclear. Here, we conducted behavioural experiments test whether monarch (Danaus plexippus) can remember retrieve the of food source. We placed several visually identical feeders flight cage, with only one feeder providing sucrose solution. Across multiple days, individual predominantly visited rewarding feeder. Next, displaced salient landmark close which visual cue used relocate While occasional displacements were ignored by did not affect their decisions, systematic displacement both demonstrated that associated feeder's position. Altogether, show consolidate context foraging.

Abstract Many predatory animals, such as the praying mantis, use vision for prey detection and capture. Mantises are known in particular their capability to estimate distances by stereoscopic vision. While initial visual processing centers have been extensively documented, we lack knowledge on architecture of central brain regions, pivotal sensory motor transformation higher functions. To close this gap, provide a three‐dimensional (3D) reconstruction Asian Hierodula membranacea . The atlas facilitates in‐depth analysis neuron ramification regions aides elucidating potential neuronal pathways. We integrated seven 3D‐reconstructed interneurons into atlas. In total, 42 distinct neuropils cerebrum were reconstructed based synapsin‐immunolabeled whole‐mount brains. Backfills from antenna maxillary palps, well immunolabeling γ‐aminobutyric acid (GABA) tyrosine hydroxylase (TH), further substantiate identification boundaries areas. composition internal organization compared anatomical fruit fly ( Drosophila melanogaster ) two available atlases Polyneoptera—the desert locust Schistocerca gregaria Madeira cockroach Rhyparobia maderae ).
