French’s Longhorn

Hi Guys
I have now found it!  Batocera frenchi
Happy Christmas holidays to you

Ed. Note:  We didn’t realize Stephen had his answer when we prepared this response.
Dear Stephen,
We believe this may be a French’s Longhorn,
Batocera frenchi, and we did considerable research several years ago when we posted a photo of a mating pair.  We found a male specimen for sale on Ebay and Insects & More lists it as rare.

Longhorned Borer Beetle

Hi Sergio,
This is a Longhorned Borer Beetle in the family Cerambycidae.  We will post your photo and continue to try to find a species identification.

Hi Daniel and Sergio:
This may be an Orange Coffee Longhorn (Dirphya nigricornis). These are the only photos I could find that match the Sergio’s beetle. The same photos appear on various sites and give the same taxonomic name, but I am not completely convinced that the identification is correct. Given its distinctive appearance and the fact that it is supposed to be a pest on coffee plants, there is surprisingly little information to be found online. To make it more confusing, the species appears to have a number of generic synonyms (Dirphya, Leuconitocris, Nitakeris, Necydalis, Nitocris, and Oberea) and I can’t figure out with certainty what the currently valid name is. Regards. Karl

Thanks Karl.  You have been busy today.

May 2008 – This was the beast that started it all for me; sheltering from the rain on the underside of a leaf in my garden in, of all places, the Niger Delta on Bonny Island, Nigeria. It certainly wasnt happy when I tried to move it to a better perch for its first photo shoot. It actually sqeeked!
It appears to fall into Longhorn territory but I cant find any other image of it. I would dearly love to know if it has a name. At 50mm long, excluding ”horns”, it is a magnificent creature. You can see how the psyche of science fiction writers would make their imagination run riot. If only I had time to go on a bug hunt here in Thailand.

Hi Bill,
We haven’t had any luck with an identification on this beautiful Longicorn in the family Cerambycidae.  We are posting your photo and we hope to have it identified before too long.
  We especially love the photo where this impressive Longhorned Borer Beetle is attempting to take flight.



Hi Daniel…
Just downloaded the Electronic version of your book to my iPad… thumbs up to that!
Glad the Longicorn is a new animal for the team… and thanks for posting it.
It made several attempts to fly off until I finally let it go.
Some of the locals were showing a bit more white in their eyes as it soared up into the massive Jungle trees on the other side of the perimeter wall.
There are one or two other unidentified “monsters” on my hard drive for you to get your teeth into.
When I find the images of Bert and Jimmy having breakfast, two huge black and orange Assassin bugs, I’ll share them with an amusing story over their sad demise to an Great African Water Diving Beetle.
Which, apparently, is the biggest “bug” in the world –  Can you confirm that?
Very much appreciate the time you devote to it all.
Thanks for doing what you do.

Longhorned Borer Beetle

Hi again Bill,
We hope you enjoy the book and we look forward to your other submissions.  We believe you are mixing up Diving Beetles with Giant Water Bugs or Toe-Biters as they are known in the U.S.  Southeast Asian Giant Water Bugs are reportedly the largest True Bugs on Earth.

Karl provides the identification of Ceroplesis adusta.
Hi Daniel and Bill:
Your longicorn looks like a species of flat faced-longhorns (Lamiinae), probably Ceroplesis adusta. It is widely distributed throughout East Africa, but I couldn’t find out much more about it. Regards. Karl.

Thanks for the assistance Karl.  Your input is always greatly valued.

This giant bug, about 4” long was found this morning in Jarabacoa. Dominican Republic.
Can you please help me identify it?

Callipogon sericeum

Dear Mario,
We know we have seen images of this beetle or a close relative previously, however, we are having problems identifying it, so we decided to post your image prior to an identification.  We do not believe it is in the genus
Callipogon, though we do believe it is in the same subfamily, Prioninae.  We checked several websites with no luck, including Coleop-Terra and the Worldwide Cerambycoidea Photo Gallery where the closest match we could find are the members of the genus Macrodontia. We did not think a beetle this distinctive would be so difficult to identify.  We are going to contact Eric Eaton for assistance.

Thank you.  I’ll await news. Hopefully we’ll be able to identify it.

Hi again Mario,
It seems you were correct with the
Callipogon identification.  Our loyal reader and frequent contributor Cesar Crash from Brazil has provided the name Callipogon sericeum as the species and the Harvard Collection of Caribbean Insects has fourteen images of mounted specimens from the collection.  We also found a matching photo on the Cerambycidae of Cuba website despite our original search of those key words coming up blank.  Perhaps not all males have such well developed mandibles, or perhaps some of the images posted online are actually of different species.  At any rate, all indications are that this species is a rarity that is commanding very high prices on online auctions of individuals nowhere near as impressive as the individual in your photograph.  Congratulations on a gorgeous photograph of a living specimen, especially since we cannot seem to find any other examples of living males with such developed mandibles anywhere online.

Every year i seem to run across this large lady bug looking bettle. They seem to love early mornings. Thats the only time i can catch them out and about. What is it?

Flower Longhorn

Hi again tx Finest,
In our opinion, this is a Flower Longhorn in the subfamily Lepturniae, however, despite finding many similar looking individuals on BugGuide, we cannot provide a conclusive identification.

I’d have to take quite a bit of time to search and find you an answer, but the color of this image is a bit off, too.

No sense searching unless you have nothing else to do Eric.  Like I wrote, there were many similar ones.  The person wrote:  “They seem to love early mornings. Thats the only time i can catch them out and about.”  Since It was early morning, I did not correct the red color of the light.  Here is a color corrected version, though it is still off color.

Flower Longhorn color corrected to remove red, morning light.

Hi, I live in the Dominican Republic and I have this picture of two largish beetles with very long antenna, black and orange striped. The beetles themselves are dark brown with a yellow band across their abdomen. Their legs are lighter brown with black joints. I have an idea they were mating as the larger one was on top of the smaller one. There was a few of them around this tree, apparently attracted to sap (actually there was almost a party going on in this tree with other bugs like butterflies and stink bugs-I think). Also, under these two you can see a quantity of white foam. This was in January and the tree I believe is a Delonix regia(Flamboyán in Spanish, Flamboyant?).
I have not been able to find anything like on the Internet, except it seems to be some kind of long-horned beetle.
Thanks for your help. Just in case, I have more pics, but I think these are best.

Mating Longicorns:  Trachyderes succinctus

Dear MDS,
We were not having any luck identifying your Longicorns in the family Cerambycidae, and the web search that eventually led us to an identification was “longicorn Hispanola.”  We identified your amorous pair as
Trachyderes succinctus on  We confirmed the identification on BioLib.  We believe the butterfly is the Dusky Emperor, Asterocampa i. idyja, based on photos posted to Butterflies of America.  Seems the Longicorns, the Dusky Emperor and the Scarab Beetles in your third photo were all attracted to the sweet, oozing sap.

Mating Longicorns and Dusky Emperor

Thank you! I was so pleased to get your answer.  I was definitely on the wrong track.  And also for identifying the other ones.
I am getting to know your site! So informative and fun at the same time. I love taking nature pics, including bugs, and now I’m going through and trying to identify them. (But I’m going to have to ban it from my work computer if I want to get anything done.)
