The first known troglomorphic, eyeless spider wasp (Hymenoptera: Pompilidae): Troglopompilus miracaecatus gen. et sp. nov. from the Nullarbor Caves, Western Australia

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
Abstract Surveys of caves of the Nullarbor Plain, Western Australia, revealed a remarkable assemblage of exceptionally well‐preserved mummified arthropods, comprising Araneae, Blattodea, Coleoptera and Chilopoda, all of which exhibit high levels of troglomorphism, lacking eyes and showing a number of other adaptations.

Glomerular organization in the antennal lobe of the oriental armyworm Mythimna separata

open access: yesJournal of Integrative Agriculture
In insects, the number and specificity of antennal lobe glomeruli often reflect the number and diversity of expressed chemosensory genes, which are linked to its ecological niche and specific olfactory needs.

Engaging and disengaging recurrent inhibition coincides with sensing and unsensing of a sensory stimulus

open access: yesNature Communications, 2017
Sensory stimuli evoke temporally dynamic responses. Here the authors report that responses to odour onset and offset are orthogonally represented in the locust antennal lobe, differentially entrain oscillations, and propose a model in which they are ...

Role of histamine as a putative inhibitory transmitter in the honeybee antennal lobe

open access: yesFrontiers in Zoology, 2006
Background Odors are represented by specific spatio-temporal activity patterns in the olfactory bulb of vertebrates and its insect analogue, the antennal lobe.

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

open access: yes, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

Description of Austrocelis gen. nov. (Diptera: Periscelididae), including the description of eight new species and the diversity and abundance of the species in different strata of the Amazon Rainforest

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
Abstract Austrocelis gen. nov. is described based on the following characters: maxillary palpus short and spatulate; setae of the head elongate; face protrudent, with the dorsal portion flattened and oblique, and ventral portion shorter and recessed towards the mouth opening; wing banded, with setae present on dorsal surface of vein R1; surstylus ...

Dynamic contrast enhancement and flexible odor codes

open access: yesNature Communications, 2018
Sensory stimuli are encountered in multiple ways necessitating a flexible and adaptive neural population code for identification. Here, the authors show that the dynamics of odor coding in the locust antennal lobe varies with stimulus context so as to ...
