Frontiers in Ecology and Evolution, 2021 Leg chordotonal organs in insects show different adaptations to detect body movements, substrate vibrations, or airborne sound. In the proximal tibia of stick insects occur two chordotonal organs: the subgenual organ, a highly sensitive vibration ...

Integrated phylogenomic and fossil evidence of stick and leaf insects (Phasmatodea) reveal a Permian–Triassic co-origination with insectivores [PDF]
Royal Society Open Science, 2020 Stick and leaf insects (Phasmatodea) are a distinctive insect order whose members are characterized by mimicking various plant tissues such as twigs, foliage and bark.

Capillary adhesion of stick insects
Annals of the New York Academy of Sciences, 2023 Abstract Scientific progress within the last few decades has revealed the functional morphology of an insect's sticky footpads—a compliant pad that secretes thin liquid films. However, the physico‐chemical mechanisms underlying their adhesion remain elusive.

Sequence, characterization and pharmacological analyses of the adipokinetic hormone receptor in the stick insect, Carausius morosus [PDF]
Frontiers in EndocrinologyBackgroundAdipokinetic/hypertrehalosaemic hormone (AKH/HrTH), corazonin (Crz) and the AKH/Crz-related peptide (ACP) are neuropeptides considered homologous to the vertebrate gonadotropin-releasing hormone (GnRH).

Supermodels: stick insects or hourglasses? [PDF]
The Lancet, 1997 Supermodels have been criticised for being a bad role model for young women because of their unnatural thinness, and have even been linked to the increase in eating disorders, such as anorexia and bulimia. We compiled a biometric database of 300 fashion models, 300 glamour models, and 300 normal women (table).

Evidence for cryptic sex in parthenogenetic stick insects of the genus Timema. [PDF]
Proc Biol Sci, 2023 Obligately parthenogenetic species are expected to be short lived since the lack of sex and recombination should translate into a slower adaptation rate and increased accumulation of deleterious alleles.

Evolutionary dynamics of specialization in herbivorous stick insects [PDF]
Ecology Letters, 2018 AbstractUnderstanding the evolutionary dynamics underlying herbivorous insect mega-diversity requires investigating the ability of insects to shift and adapt to different host plants. Feeding experiments with nine related stick insect species revealed that insects retain the ability to use ancestral host plants after shifting to novel hosts, with host ...

Attachment Performance of Stick Insects (Phasmatodea) on Plant Leaves with Different Surface Characteristics. [PDF]
Insects, 2022 Simple Summary Herbivorous insects and plants greatly affected each other’s evolution due to their close interactions. This resulted in the development of a variety of adaptations on both sides. Through the need for protection against herbivorous insects,

Disruptive selection and the evolution of discrete color morphs in <i>Timema</i> stick insects. [PDF]
Sci Adv, 2023 A major unresolved issue in biology is why phenotypic and genetic variation is sometimes continuous, yet other times packaged into discrete units of diversity, such as morphs, ecotypes, and species. In theory, ecological discontinuities can impose strong
