Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

open access: yesInsect Molecular Biology, EarlyView.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Neurons in capitate peg sensillum of maxillary palp are activated by DMDS, DMTS and sulcatone.

open access: yes, 2016
Electrophysiological activities of (A) cpA, (B) cpB and (C) cpC neurons in capitate peg sensillum (highlighted in a red box; picture modified from a previous study [35]) of maxillary palp in gravid An. coluzzii females are identified by spike amplitudes,

Visualization of antennal lobe glomeruli activated by nonappetitive D-limonene and appetitive 1-octen-3-ol odors via two types of olfactory organs in the blowfly Phormia regina

open access: yesZoological Letters, 2020
Appetite or feeding motivation relies significantly on food odors. In the blowfly Phormia regina, feeding motivation for sucrose is decreased by the odor of d-limonene but increased by the odor of 1-octen-3-ol odor.

Living cockroach genus Anaplecta discovered in Chiapas amber (Blattaria: Ectobiidae: Anaplecta vega sp.n.) [PDF]

open access: yesPeerJ, 2019
Cenozoic cockroaches are recent and with two indigenous exceptions, based on their fragmentary preservation state, they cannot be discriminated formally from representatives of living genera. Anaplecta vega sp.n.

Neurogenetic identification of mosquito sensory neurons

open access: yesiScience, 2023
Summary: Anopheles mosquitoes, as vectors for the malaria parasite, are a global threat to human health. To find and bite a human, they utilize neurons within their sensory appendages. However, the identity and quantification of sensory appendage neurons

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

open access: yesInsect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

First Zoeal Stage of the Snapping Shrimp Alpheus Fabricius, 1798 (Caridea: Alpheidae): New Description of Alpheus bouvieri A. Milne‐Edwards, 1878 and Literature Review

open access: yesActa Zoologica, Volume 107, Issue 3, Page 361-376, July 2026.
ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...

Comparative study of larval head structures of Megaloptera (Hexapoda)

open access: yesEuropean Journal of Entomology, 2008
External and internal head structures of the larva of Neohermes are described in detail. The results are compared to conditions found in other representatives of Corydalidae, in Sialidae, and in Raphidioptera and Neuroptera.

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...
