Mechanosensory encoding of forces in walking uphill and downhill: force feedback can stabilize leg movements in stick insects.

J Neurophysiol
Force feedback could be valuable in adapting walking to diverse terrains but the effects of changes in substrate inclination on discharges of sensory receptors that encode forces have rarely been examined.

Cretaceous winged stick insects clarify the early evolution of Phasmatodea. [PDF]

Proc Biol Sci, 2019
Wingless and shorter winged stick insects are very common today, but most known extinct stick insects had fully developed wings, leading to contentious affinities among the extinct winged and extant groups.

Shear-sensitive adhesion enables size-independent adhesive performance in stick insects. [PDF]

Proc Biol Sci, 2019
The ability to climb with adhesive pads conveys significant advantages, and is hence widespread in the animal kingdom. The physics of adhesion predict that attachment is more challenging for large animals, whereas detachment is harder for small animals ...

Influence of surface free energy of the substrate and flooded water on the attachment performance of stick insects (Phasmatodea) with different adhesive surface microstructures.

Journal of Experimental Biology, 2023
Stick and leaf insects (Phasmatodea) are exclusively herbivores. As they settle in a broad range of habitats, they need to attach to and walk on a wide variety of plant substrates, which can vary in their surface free energy (SFE).

Influence of native and exotic plant diet on the gut microbiome of the Gray's Malayan stick insect, Lonchodes brevipes

Frontiers in Microbiology, 2023
Herbivorous insects require an active lignocellulolytic microbiome to process their diet. Stick insects (phasmids) are common in the tropics and display a cosmopolitan host plant feeding preference.

Evidence for cryptic gene flow in parthenogenetic stick insects of the genus Timema

bioRxiv, 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.

Consequences of Asexuality in Natural Populations: Insights from Stick Insects. [PDF]

Mol Biol Evol, 2018
Recombination is a fundamental process with significant impacts on genome evolution. Predicted consequences of the loss of recombination include a reduced effectiveness of selection, changes in the amount of neutral polymorphisms segregating in ...

The genome of the stick insect Medauroidea extradentata is strongly methylated within genes and repetitive DNA. [PDF]

PLoS ONE, 2009
BACKGROUND: Cytosine DNA methylation has been detected in many eukaryotic organisms and has been shown to play an important role in development and disease of vertebrates including humans.

Dispersal of Phraortes illepidus (Phasmida: Phasmatidae) Eggs by Workers of the Queenless Ant, Pristomyrmex punctatus (Hymenoptera: Formicidae)

Sociobiology, 2021
Eggs of some stick insects bear external appendages called capitula. Foraging worker ants attracted by capitula disperse eggs in a response similar to the responses of workers to elaiosome-bearing seeds of many plants.
