SWERVING STICK INSECTS

Journal of Experimental Biology, 2005
![Figure][1] Watch a stumbling toddler and you'll see that we struggle to learn how to control just two legs. But spare a thought for the humble stick insect; it has to coordinate 18 leg joints as it ambles around.

Divergence time and environmental similarity predict the strength of morphological convergence in stick and leaf insects

Proceedings of the National Academy of Sciences of the United States of America
Significance Phasmids (stick and leaf insects) exemplify the extraordinary power of natural selection to shape organismal phenotypes. The animals themselves are charismatic exemplars of crypsis and masquerade; and our characterization of their adaptive ...

Egg chorion architecture in stick insects (Phasmatodea)

International Journal of Insect Morphology and Embryology, 1993
Abstract Comparative analysis of egg chorion architecture by scanning and transmission electron microscopy is reported in about 50 species of stick insects (Phasmatodea). Particular attention has been paid to: (1) synthesis and structure of egg shell layers; (2) egg shape; (3) morphology of the external chorionic surface; (4) position and structure ...

Feeding Habits of Stick Insects

Nature, 1937
IN reference to the communication from Mr. Sidney T. E. Dark1, and the observations from the Notre Dame Training College, Glasgow2, relating to the eating of dead cellulose by Carausius, it may be of interest to record that these insects will occasionally eat paper.

Dynamics of the walking stick insect

Proceedings., IEEE International Conference on Robotics and Automation, 2002
In order to gain insight into the biological constructional conception of walking as a basis for future technical developments, the gait dynamics of the walking stick insect (Carausies morosus) is investigated. It is modeled by a rigid multibody system consisting of 19 bodies and forming multiple closed kinematic chains corresponding to the regarded ...

Microtubules in the spermatids of stick insects

Journal of Ultrastructure and Molecular Structure Research, 1988
Spermatids from two phasmid species were seen to possess an unusually large amount of microtubules along the nucleus and tail. Some of the microtubules have a loosely fitting sleeve for half a micron or more. During late stages in spermiogenesis the microtubules aggregate and form one or several "microtubular crystals" consisting of electron-lucid ...

How stick insects got their colors

Science, 2020
Ecological Genomics Stick insects of the genus Timema show variations in color that are likely due to selection for camouflage on their plant hosts. Some species are only brown or only green, whereas others span from reddish-pink hues to green to brown. To identify the genetics underlying this variation, Villoutreix et al.
