Order Phasmida: the stick insects (or walkingsticks) and leaf insects — Examples

Families represented below:
Diapheromeridae (the diapheromerid stick insects)
Phasmatidae (the phasmatid stick insects)
Pseudophasmatidae (the striped walkingsticks)

Phasmatidae, the phasmatid stick insects

Titan Stick Insect (Acrophylla titan)
Titan Stick Insect, Acrophylla titan, family Phasmatidae (the stick insects).
Photographed and identified by: Peter Rowell. Location: northern New South Wales, Australia. Date: 15 January, 2017. Peter described this insect as “a rather large Stick Insect about 30cm long.” Yes, that qualifies as rather large, Peter!
Titan Stick Insect (Acrophylla titan)
Titan Stick Insect, Acrophylla titan, family Phasmatidae (the stick insects).
□ This is the same insect as shown in the previous photo. Its common and scientific names include “titan” — an apt decription!
Photographed and identified by: Peter Rowell. Location: northern New South Wales, Australia. Date: 15 January 2017.

Pseudophasmatidae, the striped walkingsticks

Northern Walkingstick (Diapheromera femorata)
Devil Riders, or Southern Two-Striped Walkingsticks, Anisomorpha buprestoides, family Pseudophasmatidae (the striped walkingsticks). Photographed and identified as walkingsticks by: Mechele Harrington. Identified to species by: Thies Büscher. Thank you, Dr. Büscher! Location: Beach City, Texas, USA. Date: 18 August, 2017.
Northern Walkingstick (Diapheromera femorata)
Devil Riders, or Southern Two-Striped Walkingsticks, Anisomorpha buprestoides, family Pseudophasmatidae (the striped walkingsticks).
□ This is a great shot of the antennae, which are more than half as long as the body.
Photographed and identified as walkingsticks by: Mechele Harrington. Identified to species by: Thies Büscher. Thank you, Dr. Büscher! Location: Beach City, Texas, USA. Date: 18 August, 2017.

Northern Walkingstick (Diapheromera femorata)
Devil Riders, or Southern Two-Striped Walkingsticks, Anisomorpha buprestoides, family Pseudophasmatidae (the striped walkingsticks).
Photographed by: Logan Bush. Identified to species by: Thies Büscher. Thank you, Dr. Büscher! Location: northwestern Florida, USA. Date: 5 September, 2017. Logan says, “It is about 3–4 inches long (7.6–10.2 cm).
Northern Walkingstick (Diapheromera femorata)
Devil Riders, or Southern Two-Striped Walkingsticks, Anisomorpha buprestoides, family Pseudophasmatidae (the striped walkingsticks).
□ As with other species of walkingsticks, the female is much larger than the male.
Photographed and identified as walkingsticks by: Mechele Harrington. Identified to species by: Thies Büscher. Thank you, Dr. Büscher! Location: Beach City, Texas, USA. Date: 18 August, 2017.
Add your photo here! Devil Rider (<i>Anisomorpha buprestoides</i>)
Devil Riders, or Southern Two-Striped Walkingsticks, Anisomorpha buprestoides, family Pseudophasmatidae (the striped walkingsticks).
□ Devil riders are sometimes known as musk mares. This refers to the pungent musky spray that they can emit. It’s an excellent defense mechanism, because the spray is irritating and painful when it comes in contact with the eyes, the mouth and other mucous membranes.
Photographed and identified by: Maryle Barbé. Location: Bonita Springs, Florida, USA. Date: 28 November, 2013.
Devil Rider (<i>Anisomorpha ferruginea</i>)
Devil Riders, also known as Northern Two-Striped Walkingsticks, Anisomorpha ferruginea, family Pseudophasmatidae (the striped walkingsticks).
□ Look closely! This is actually a mating pair. A small male is on top of the much larger female.
Photographed and identified by: Kelly Ray. Location: Tyler, Texas, USA. Date: 22 June, 2017.

Diapheromeridae, the diapheromerid stick insects

Northern Walkingstick (Diapheromera femorata)
Northern Walkingstick also known as Common Walkingstick, juvenile, Diapheromera femorata, family Diapheromeridae (the diapheromerid stick insects).
□ This Northern Walkingstick is holding its front pair of legs straight out frontwards from the head (on the left in this photo), so the legs look almost like long antennae. The juveniles of this species are green (as shown), and the adults are brown. Most people never see them because they like to stay up in trees, especially in cherry, oak, and American elm, but also in other hardwood trees. This is a wingless species. Note: It is sometimes erroneously listed as being a member of the family Heteronemiidae.
Photographed by: Rhonda Baxter. Identified by: KnowYourInsects.org Location: Ypsilanti, Michigan, USA. Date: August, 2015.
Phasmid Egg Casings
Egg casings of a Stick Insect in the genus Trachythorax, subfamily Necrosciinae, family Diapheromeridae (the diapheromerid stick insects).
□ A mystery solved! The photographer suspected this intricate structure (2-3 cm or about an inch long) was a cluster of insect eggs. Expert Thies Büscher of the Zoological Institute at Kiel University in Germany confirmed that it was indeed eggs, and suspected they may be from a species in the subfamily Necrosciinae. A few months later, the photographer (Vandan Jhaveri) happened upon someone else’s posting of a photo of a stick insect with eggs that look just like the ones in this photo, and that stick insect is in the genus Trachythorax.
Photographed and identified as walking stick eggs by: Vandan Jhaveri, Varad Giri, Rahul Khot and “few Facebook groups.” Identified to subfamily by: Thies Büscher. Thank you, Dr. Büscher! Identified to genus by a Facebook post by Varad Giri, which Vandan spotted. A team effort! Location: Phansad Wildlife Sanctuary, Maharashtra, India. Date: 12 January, 2018.
Phasmid Egg Casings
Egg casings of a Diapheromerid stick insect, possibly in the subfamily Necrosciinae, family Diapheromeridae (the diapheromerid stick insects).
□ The photographer of the previous photo ventured out again, found additional egg casings, and took this close-up photo.
Photographed and identified as walking stick eggs by: Vandan Jhaveri. Location: Sanjay Gandhi National Park, Mumbai, India. Date: 18 February, 2018. Vandan says he later found another one, however each egg’s operculum (or cap) was already opened, so “all must have hatched.” Vandan points out that the eggs unfurl like flower petals and believes they do so soon after the eggs are being laid.
