Hi , my name is Justin I collect insects as a hobby and have taken a couple entomology classes, but I can’t ID this insect. It looks like some sort of a longhorn beetle . But I believe this is husk or shell. Is this possibly a nymph stage of an insect? This was found in November 2013 near Gaitlinburg TN USA.

Unknown Katydid Nymph

Fungus Infected female Carolina Leaf Roller

Hi Justin,
WE are having trouble providing you with a definitive identification, but we can tell you this is not a Longhorn Beetle.  This is an Orthopteran in the suborder Ensifera, the Longhorned Orthoptera.  Furthermore, we believe it is an immature Katydid in the family Tettigoniidae, and the presence of an ovipositor indicates it is a female.  This does not appear to be a shed exoskeleton, as there is no evidence of a splitting along the dorsal surface which is where the newly metamorphosed insect would emerge from a cast-off exuvia.  Your image is not as sharp as we would like, and we are uncertain if those are spines on the body, or perhaps the remnants of a fungal infection.  There are several examples on the Field Biology in Southeastern Ohio page of Carolina Leaf Rollers infected with
 Cordyceps fungus that look very similar to your image, and we believe that might be an accurate identification.  The description on the site states:  “Another body invading fungus is Cordyceps. They are known to attack at least a dozen different orders of insects. This is a Carolina Leafroller, Camptonotus carolinensis, a katydid relative.  The dark spot at the base of the abdomen, and the long ovipositor verify this as a female leafroller. Cordyceps fungi may be more familiar to some with regards to ants. This is the same genus that affects the brains of certain ants, turning them into zombies. They climb to high points on vegetation, then the fungal spores spring out of their head. Infected ants are recognized by the colony, and individuals are removed so they won’t cause the entire population to die.”  So, after our research, we are concluding that this is a female Carolina Leaf Roller, a Raspy Cricket, that has been infected by Cordyceps fungus.

Raspy Cricket

Dear GRANNY,
You really don’t need to worry much about this Raspy Cricket in the family Gryllacrididae and likely in the genus
Ametrus.  We identified it from our own archives thanks to the input of a noted Katydid expert, Piotr Naskrecki.  What appears to be a stinger is actually the females ovipositor, an organ used in the laying of eggs.

THANKYOU DANIEL FOR YOUR FAST REPLY…I AM VISION IMPAIRED AND ACTUALLY THOUGHT IT WAS A HUGE SPIDER THAT LANDED ON MY SHOULDER..I SCREAMED SO FRIENDS CAME RUNNING AND FOUND THE INSECT..IT WAS THEY WHO NEEDED IT IDENTIFIED AND TY SOO MUCH…GOOD LUCK WITH YOUR GREAT WORK..GRANNY..

Cricket from India
Location: Agumbe, Karnataka, India

This photo of an unidentified cricket was taken in January by a trip mate on a recent adventure in India. The antennas must have been near a foot long! She was on a fence post with her ovipositor out, so we tried not to disturb her too much. Any ID would be greatly appreciated!

Raspy Cricket

Dear Brian,
We are not certain if this Longhorned Orthopteran is a Katydid or a Raspy Cricket, which is what we are leaning towards.  We will contact Katydid expert Piotr Naskrecki to get his input.

Hi Daniel,
You are correct, this is a raspy cricket. The easiest way to tell them apart is to look at the front tibia: a katydid will have tympanum (or a least a tympanal slit) below the knee, raspy crickets don’t have them. Unfortunately, I will not be able to tell you more about this Indian species other than that it is possibly (with a big question mark) a member of the genus Pardogryllacris.

Tsingy Bemaraha Katydid

Hi there
I recently found this on the Bemaraha plateau at the village of Bevero in Madagascar. Have you any idea if it has been seen before? A designation down to species would be appreciated if possible. What possible advantage could there be in this shocking green and pink combination? Your thoughts please, Thank you. Len

Raspy Cricket from Madagascar

Hi Len,
We will contact Katydid expert Piotr Naskrecki to see if he can identify this species which is possibly an immature specimen since it is lacking wings.  We don’t have a theory on the advantage of the coloration of this Katydid.

Piotr Naskrecki Responds
Hi Daniel,
This is not a katydid but a nymph of a gryllacridid, also known as a leaf-rolling or raspy cricket. But it would be difficult to ID the genus at this stage as this is a very young nymph.
Cheers,
Piotr

Insect from Kilcowera Station

Hi bugman! Love your website, so handy!It’s early summer here in Oz and these insects are all over the place in their little homes growing big, ready to fly.
They live in bricks,small diameter steel pipes and in suitable bits of steel and other things that have a nice cosy hole that they can cover at one end.
Do they bite? They look quite terrifying and I hate the look of them. They start off only a couple of centimetres long and can get to about 8 cm.

Striped Raspy Cricket

Hi Toni,
We identified your insect as a Striped Raspy Cricket,
Paragryllacris combusta, on the Brisbane Insect website which states:  “Striped Raspy Crickets are also known as Tree Crickets. Adults are dark brown to pale brown in colour with fully developed wings. They have very long antenna, all legs are spiny.  They hide in nest on tree during the day. Their nest is usually two board leaves hold together by silky material. They are well known for their ability to find the way home after foraging distance away.”  You indicate that they live in bricks and pipes, and provided a photo of the covering they create at one end.  We did additional research and learned on Bush Craft Oz that they are:  “Large cricket (body up to 45 mm), nocturnal feeder, spends day in tree holes, or, more usually, two leaves stuck together with silk like material. Can navigate home each night. Has been observed nectar feeding. Fully developed wings. Patterns on face.”  Since they spend the diurnal hours in tree holes, they are probably using your bricks as a substitute lair.  We are intrigued with their ability to spin silk.  The sword-like ovipositor on your individual indicates she is a female.

Silken Lair of the Striped Raspy Cricket

Well thank you very much for your speedy response.  I have never seen their nest in trees! I have observed however that it seems it’s the smaller ones hide behind the white silk like stuff and don’t come out for a fee weeks, then one day the white stuff will have been broken or eaten away and the insect is gone.  And they get much bigger than 45ml!!!  Do they bite?????  Regards Toni

Many large Orthopterans can bite, but we have no knowledge of the Striped Raspy Cricket being a biter, though we would surmise that they would only bite if carelessly handled.

Katydid, grasshopper, or cockroach? Please let it be one of the first two…

Hello, My husband found this insect in our northeast Ohio dining room. Our house is bordered by a large wooded area so I am thinking that it may be a katydid. However, I always worry when I see a large bug like this (can’t help myself)

Carolina Leaf Roller

Dear worried in Ohio,
Though your photo is blurry, we believe that, based on this photo posted to BugGuide, this is a female Carolina Leaf Roller,
Camptonotus carolinensis, which is classified as a Raspy Cricket in the family Gryllacrididae.  It isn’t classified in either the cricket family or the katydid family, though all three families are grouped together as Long-Horned Orthopterans in the suborder Ensifera.  According to BugGuide, it is a beneficial insect that:  “Hunts aphids at night.”
