This is another stick insect, but this time I think it’s a mature specimen.
It was on august 2009, in Peru amazonia.
Can you help me to identify the species?

Stick Insect

Hello again Ferran,
We found an image on Alamy of mating Stick Insects from Peru that looks exactly like your male Stick Insect, but alas, it is not identified by species.  Based on this Insetologia image, this FlickR image and this BioDiversidade image, we believe it might be in the genus

Thanks one more time, Daniel.
I can see that stick insects are very difficult to identify, so my thanks to you are strong this time.
I’ll send you more insects soon. 😉

Hi again,
I know nothing about stick insects, so for me it’s difficult to identify the species.
It was on may 2016.
I hope you can help me.
Thank you.

Stick Insect

Dear Ferran,
This appears to be an immature individual, and correct identification of mature specimens is often quite difficult.  We are unable to provide you with a species identification at this time, but perhaps one of our readers will provide a comment.

Narrowed it down between a Goliath, crown or a titan.
Approx 15cm long not including legs.

Stick Insect:  Adult male Ctenomorpha marginipennis

Dear Jess,
Your individual appears to have very long antennae.  The Goliath Stick Insect pictured on Brisbane Insects has very short antennae.  According to Oz Animals, “The Crown Stick Insect is found in coastal Queensland and the Northern Territory” and it also appears to have short antennae.  Titan Stick Insect images on FlickR also have short antennae.  Using the long antennae as a diagnostic feature, and based on the slim body of your individual, we would entertain that this might be a Dark-Winged Stick Insect,
Mesaner sarpedon, which is pictured on the Brisbane Insect site.  The Atlas of Living Australia does not have any images, but there is a sighting documented near Sydney.  Unfortunately we cannot find any information on the size of the Dark-Winged Stick Insect.  Perhaps a Phasmid expert will write in with a correction or an affirmation.

Thank you very much. I’ll get onto finding out more!

I have received a reply from an entomology group on Facebook and they seemed very sure on this.

I have found many of these this fall around my porch and a few under my mobile home. I am worried because I need to work under the mobile and wonder if a bite or sting is possible. How do I get rid of them?

Mating Muskmares

Dear Freaked Out,
These are indeed mating Walkingsticks.  Commonly called Muskmares, adult Southern Two-Lined Walkingsticks,
Anisomorpha buprestoides, are frequently encountered as mating pairs.  Of the species, BugGuide indicates:  “Three color forms, two of them only found in limited areas:  White form, only found around Ocala National Forest, Orange form, only found around Archbold Biological Station.”  It appears you have a small white form male (you are in Ocala) mating with an orange female, so perhaps the orange form is increasing its range.  Though they do not sting nor bite, they do have an effective defense mechanism that should concern you.  According to Featured Creatures:  “this species is capable of squirting a strong-smelling defensive spray that is painfully irritating to the eyes and mucous membranes.”  According to Wilderness & Environmental Medicine:  “this phasmid’s intriguing, elongated body shape makes its existence well known, most are unaware of its chemical defense mechanism for warding off predators. Anisomorpha buprestoides, a common walkingstick in the southeastern United States, has the ability to eject an offensive spray from its thorax with pronounced accuracy. Although birds, spiders, and reptiles are likely their main nemeses, they take no pity on threatening mammals, including reported cases involving canines and humans. The arthropods target the eyes and have caused documented ocular injury ranging from conjunctivitis to corneal ulceration.”

I have seen 3 of these in my garage lately. I would like to know what it is and if it is dangerous for my toddlers.

We found what appears to be the same species of Walkingstick on Project Noah where it is identified as “Autolyca elena Gorochov & Berezin, 2008″ referred to as a Scorpion mimic:  “This is a walking stick which is imitating a scorpion. It is shiny black and carries the tail end curled up over the abdomen. It is remarkably like a scorpion in general appearance and behavior. However, it is phytophagous and not a predator nor can it sting. It also has extremely long antennae which are banded orange and black and of course, only 3 pair of legs. This is a male.”  There are also images on iNaturalist.  Some Stick Insects can spray chemical defenses, but we do not know if this is one of those species.

Thank you so much!  I am a bit more at ease with the fact that it does not sting!

Stick Insect

Dear AP,
This is a Katydid, and it appears to be a species that mimics bark to help camouflage it from its enemies.  It resembles this Katydid from Panama that Katydid expert Piotr Naskrecki identified as
Acanthodis curvidens.  There is an image on Visuals Unlimited that is identified as that species as well.  We will attempt to contact Piotr Naskrecki for verification.

Piotr Naskrecki provides a correction.
Hi Daniel,
Not only is this not the same species, it is not even the same order. This animal is a phasmid (stick insect) Prisopus sp. (Phasmida: Pseudophasmatidae). These animals are chemically protected and produce a strong, repellant smell when disturbed.

Hello Daniel,
Still a little confused, The Prisopus actually only had 2 legs on each side while ours has 3, does that make a difference? Please advise.
Thank you,

All insects have six legs, but some insects position themselves in such a way as to conceal body parts, including legs.
