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)

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.”

Unusual Orthoptera?

August 29, 2010 10:08 am Dear Bugman,
I wonder if you can identify this odd insect that I found on my front porch light. I live in rural Southern Ohio and have never seen any insect like this. Hopefully you can tell by the photo, it appears to be wingless, has extremely long curling antennae, and a large stinger or ovipositor. I believe it is order Orthoptera, and looks similar to the shield back katydid, but not exactly. Any ideas? Thank you!

Thanks for writing back! Attached is a much better picture taken with a digital camera. Hope this helps!

Carolina Leaf Roller

Hi again Hilary,
Thanks for sending a much better image.  Even though some parts of the body are obscured, we cannot imagine that this could be anything other than a Raspy Cricket in the family Grillacridadae known as the Carolina Leaf-Roller,
Camptonotus carolinensis.  You can compare it to this photo on BugGuide. The information page on bugGuide indicates it:  “Hunts aphids at night” and “Bites through leaf in order to form flap. Flap is folded over, edge is pulled down with legs, and then edges are glued together with silk from gland on mouth. Sometimes uses empty Bladdernut (Staphylea) pods in which to hide instead of leaves.”  BugGuide also notes:  “Runs rapidly. Antennae very long, at least five times as long as body. (These do not stick out of leaf shelter.) Ovipositor is upturned and carried over back.

Wow thank you! That is definitely it! I have never seen one of these around my home, so it was great to get info on this unusual cricket! Thanks for your help,

My cousin found an unsual cricket at the backyard. It has wings and the head is black colored. It a little aggressive when I tried to touch it.

Raspy Cricket

After I took the pictures, it hopped liked a grasshopper with its wings still spread and headed towards the plants. I wasn’t able to take the picture with its wings retracted.

Raspy Cricket

Hi Neil,
That is one crazy looking insect.  It is a Longhorned Orthopteran in the suborder Ensifera, and we believe it is a Katydid in the family Tettigoniidae, most likely a predatory species.  We will check with Piotr Naskrecki, an expert in the family, to see if he recognizes this spectacular creature with its aggressive threat posture.

Hi Daniel,
This is not a katydid, but a member of Gryllacrididae, a distantly related
family. Most of them, if not all, are voracious predators that actively hunt
prey by constantly running along branches in search of insects. I cannot say
what genus it is, possibly Gryllacris or Caustogryllacris;  very little work
has been done on this group since the 1920s.

Winged Weta?
I have previously sent you an email regarding this lovely animal. I was in tears as I took the photos (having sprayed it to keep it immobile while I photographed it – sorry). It appears identical to a Weta that you have posted, except that this one has very large wings! Isn’t a “winged Weta” a contradiction in terms? Hope you can help to identify this lovely animal. She was beautiful. Note: It was found on the fringe of the arid lands in South Australia (300 Kilometres North of Adelaide).
Les Clayton

Hi Les,
We hope your tears are an indication that you will not be killing creatures in the future just to photograph them. This is not a Weta. The long ovipositor indicates the specimen is a female. It is a longhorned Orthopteran in the suborder Ensifera, and probably a Katydid in the family Tettigoniidae, but we have not had any luck identifying the species. The Geocities site did not provide any convincing matches. It appears as though the antennae on your specimen have been damaged, either through rough living, or traumatic dying, or possibly post mortem. Grev and Trevor frequently assist us with Australian species, and they may have better luck than we have had with a species identification on this striking specimen.

Update: (07/03/2008) Katydid IDs from Piotr Naskrecki
I have been looking at the page with unidentified katydids (Katydids 2), and thought I could help with some ID’s. From top to bottom they are: Australian Raspy cricket (not a katydid but a member of Gryllacrididae) possibly Ametrus sp.

Katydid or Grasshopper?
Dear Bugman,
I’m eager to know exactly what this guy is. I found him trapped in an umbrella this morning (July 8th) and when I freed him he bit me. I dropped him and he assumed a very angry and threatening pose and even chased me around the street. He either couldn’t fly, or chose not to because he ran everywhere, almost like a cockroach. He was an able climber and scaled a wall to make his escape. It was very ungrasshopper-like behavior, and after reviewing your grasshopper/katydid page, I’m beginning to wonder if he’s the latter. I snapped a few pictures, one with his wings exposed and one without (see links). I live in Fukushima Prefecture, Japan. I hope you can tell me what the hell he is!

Hi Brian,
We don’t have access to information that would identify the species or genus, but this may be one of the Katydids in the family Tettigoniidae. It reminds us of one of the predatory species in the U.S. Neobarrettia spinosa, and could be closely related.

Update: (07/03/2008) Katydid IDs from Piotr Naskrecki
I have been looking at the page with unidentified katydids (Katydids 2), and thought I could help with some ID’s. From top to bottom they are: Japanese “katydid” – not a katydid but Gryllacrididae, Prosopogryllacris japonica
