Adhesive and frictional tarsal pads in stick insects
Insects rely on specialized attachment systems to adhere to and move across substrates. For this purpose, stick insects (Phasmatodea) employ two types of smooth attachment pads on their tarsi: the pretarsal arolium, responsible for adhesion, and the tarsal euplantulae, generating friction. These …

Molecular adaptation to low-temperature in New Zealand stick insects
… this adaptation. The unusual incidence of alpine sticks insects within New Zealand suggests these species have suitable cold-tolerant phenotypes and genotypes warranting investigation. The objectives of this thesis were to: (i) verify the application of RNA-Seq to identify mild cold-shock …

Evolutionary physiology of New Zealand stick insects: A thermal biology approach
… is limited to a few model organisms. New Zealand stick insects are a monophyletic group that originated from New Caledonian tropical ancestors and currently occur in habitats ranging from subtropical to temperate and alpine. This work aims to understand if the physiology of different lineages of …

Reproductive Genomics in the Stick Insect Clitarchus hookeri
Stick insects (Phasmatodea) are orthopteroid insects that are famous for their natural camouflage to the foliage of the plant on which they feed. Parthenogenesis is common among these insects, with 10% of the taxa scattered in different families being completely or partially parthenogenetic. These …

Decentralization and Hierarchical Organization for Control of Adaptive and Cognitive Behavior in Autonomous Robots
… disturbances. Detailed experimental findings in insects suggests that this evolved flexibility results from a hierarchical and decentralized architecture. While a lower control level coordinates muscle activation patterns and joint movements on a short timescale, a higher level handles action …

Biomechanics of the fibrillar adhesive system in insects
… beetle Gastrophysa viridula and smooth pads of stick insects (Carausius morosus) was compared. Adhesive and frictional stresses were found to be similar in smooth and hairy pads, inconsistent with contact splitting theory, which predicts higher adhesive stresses for fibrillar adhesives. Hairy …

Functional characterisation of the hypertrehalosaemic hormone from the Indian stick insect Carausius morosus: metabolic and myotropic studies
… regulators for many physiological processes in insects, notably energy metabolism, and a possible role in myostimulation. The Indian stick insect Carausius morosus contains two members of this family, hypertrehalosaemic hormone I and II (Carmo-HrTH-I and -II). Both these are decapeptides and …

Ultrastructure and functional morphology of adhesive organs and anti-adhesive plant surfaces
… Both animals under inverstigation, the Indian stick insect Carausius morosus and the Australian tree frog Litoria caerulea, possess adhesive organs classified as “smooth pads”. The adhesive organ of the stick insects, the arolium, revealed to consist of a layered setup. Underneath the surface …
