The Evolution of Tarsal Adhesive Microstructures in Stick and Leaf Insects (Phasmatodea)
Insects have developed specialized structures on their feet for adhering to surfaces, with stick and leaf insects or Phasmatodea exhibiting an unexpectedly high diversity of these structures. In Phasmatodea, attachment on different substrates is achieved

Insect‐Inspired Resilient Machines
This study presents a decentralized resilient control for legged robots, enabling self‐organized locomotion and rapid adaptation to extreme leg loss within seconds. It encodes the self‐embodied resilience strategies observed in stick insects and relies on neural dynamics with synaptic plasticity, minimal sensory feedback, and dynamic robot–environment ...

De novo transcriptome analysis of the excretory tubules of Carausius morosus (Phasmatodea) and possible functions of the midgut 'appendices'. [PDF]
The Malpighian tubules are the insect excretory organs, responsible for ion and water homeostasis and elimination of nitrogenous wastes. Post-genomic assays suggest they also metabolize and detoxify xenobiotic compounds and have antimicrobial properties.

Native insect species should be selected for classroom rearings
Rearing insects in the school classroom can build positive attitudes towards insects among schoolchildren, which is becoming increasingly important as insect populations decline. Identified frequent use of non‐native insect species, raising environmental and ethical concerns after classroom rearing ends.

Genomic data support the definition of a new elateroid family, Badmaateridae fam. nov., with Badmaater chilensis gen. nov. sp. nov. as the only representative. Badmaateridae is sister to an extensive clade containing fireflies, soldier beetles, net‐winged beetles and click beetles.

A newly recorded species of the genus Lopaphus Westwood, 1859 (Phasmida: Lonchodidae: Necrosciinae) from China [PDF]
One species of Lopaphus (Phasmida: Lonchodidae: Necrosciinae), namely L. sphalerus (Redtenbacher, 1908), is reported from China for the first time. The identification of this species is primarily based on female morphological characters: cerci triangular,

Sexual conflict as a constraint on asexual reproduction: an empirical review
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

The ecological and genetic mechanisms that determine Phasmatodea reproductive biology are poorly understood. The order includes standard sexual species, but also many others that display distinct types of parthenogenesis (tychoparthenogenesis, automixis,

In this study, we analyzed individuals with male‐specific characters that emerged in an 8‐year captive isofemale line of Neohirasea japonica, a parthenogenetic stick insect from Japan. A total of three “male‐like” individuals (with a penis and without oviposition) were observed during this period.

Analysis of the gut microbiota of walking sticks (Phasmatodea) [PDF]
Abstract Background Little is known about the Phasmatodea gut microbial community, including whether phasmids have symbiotic bacteria aiding in their digestion. While symbionts are near ubiquitous in herbivorous insects, the Phasmatodea’s distinctively thin body shape precludes the gut enlargements needed for ...
