Leaf Beetle Larva

Leaf Beetle Larva

Dear Dylan,
We received your submission with three unrelated insects attached to a single, very brief identification request.  Before we could even begin, we needed to research the location of “brisdane moggil” which we quickly learned was a spelling error of Brisbane Moggil, an area in Queensland Australia.  We try to the best of our ability to classify postings correctly on our site and information on the sighting is often very helpful.  With that stated, one of your images is of a Leaf Beetle Larva.  If you want any additional identifications, please submit a single individual, but you may attach as many as three images of that individual as sometimes multiple views assist in our identification process.  Please include any relevant anecdotal information regarding the sighting.

I found this little creature 2 days ago, sitting quietly on a leaf in a park just outside of Taipei, Taiwan. It’s about one centimeter long, and it wasn’t moving; just sitting there minding its own business. A quick image search shows “slug moth” as a possible candidate, but I couldn’t find anything quite like it. Any ideas? Many thanks! :)

Leaf Beetle Larva, we believe

Leaf Beetle Larva, we believe

Dear Robert,
In our opinion, this is most likely a Leaf Beetle Larva, probably a Tortoise Beetle Larva in the subfamily Cassidinae and not a Slug Moth Caterpillar.
  It looks similar to this individual from Belize from FlickR as well as this individual from our archives.

Dear Daniel,
Thank you so much for identifying my photo as belonging to a Tortoise Beetle larva! I think you were spot on, as I took the photo only 2 minutes after I photographed a Mottled Tortoise Beetle only a meter away. The larva is so eye-catching that I didn’t make the connection, but now I can clearly see that the black markings on the adult beetle wings mirror the black markings on the larva. I’ve attached photos that I took of each.
Kind regards,
Robert

Tortoise Beetle

Tortoise Beetle

Dear Robert,
Thanks so much for the update.  We cannot say for certain that the Tortoise Beetle and the larva are the same species, but their proximity to one another is a stronger indication than the similarity in the markings as adults often differ drastically in appearance from the larvae.

I just recently moved in to a new apartment and since the first day I’ve been finding these little bugs. I have no idea what they are. I find them mainly in the living room and by the kitchen and upstairs window. Usually they are dead, or playing dead. I think they can fly by I haven’t seen them do it. But I am really tired of finding them. Is there any way to get rid of them naturally?

Elm Leaf Beetle

Elm Leaf Beetle

Dear bugged out,
This is some species of Leaf Beetle, and we believe the Elm Leaf Beetle,
Xanthogaleruca luteola, which is pictured on BugGuide is a close match and distinct possibility.  According to BugGuide:  “Native to w. Palaearctic(4), adventive and now widespread in N. America (more common in sw US).”

Hello!
Could you tell me what kind of beetle this is? I frequently see them wandering around the garden – when picked up, they grab onto your finger and then cover it in some kind of weird red liquid.
I assume they’re trying to pretend they bit you?
Either way, as such a frequent visitor, it’s a bit annoying not knowing their name!

Darkling Beetle

Leaf Beetle

Dear Kinyonga,
The best we are able to provide at this time is a family name.  This is a Darkling Beetle in the family
Tenebrionidae.  We did a quick search but could not find any matching images with identifications.  Perhaps one of our readers will have better luck with a species name.

Leaf Beetle

Ed. Note:  Thanks to a comment from beetlehunter, we now know that this is actually a Leaf Beetle, Timarcha tenebricosa, which is well represented in online images including these images on Nature Spot and Panoramio.  Nature Spot indicates the common name Bloody-Nose Beetle and states:  “It earns its common name from its peculiar form of defence; when threatened it exudes a drop of bright red fluid from the mouth. The larvae are a metallic bluish colour.”  That is illustrated on Fotonatura.  It is very interesting that the species name in the binomial shares the same root as the family name Tenebrionidae, so the resemblance Darkling Beetles was noted by Fabricius when he named the beetle in 1775.

I took this picture of an iridescent beetle at the Iguacu Falls in Brazil.
Can you please identify it.

Dear Ian,
This is a Tortoise Beetle in the tribe Cassidini, and it is similar to this individual on Insetologia.  We located an image on FlickR of
Cyrtonota cyanea that looks like a very good match to your Tortoise Beetle.  We found an image of a mounted specimen on Cassidinae of the World, but dead specimens of Tortoise Beetles often lose their beautiful coloration.

Hi There, We’re on the South Coast of Western Australia and found this little fella in our kitchen- it’d obviously flown in.
At first we thought it was a Ladybug/Ladybird but after some research now think it’s some kind of Tortoise Bug but don’t know for sure.
After taking a couple pics we let him go outside. :)

Leaf Beetle

Dear Jo,
We agree with you that this is some species of Tortoise Beetle, but we had no luck attempting to identify it to the species level.  We could not find any matching images on the Insects of Brisbane website.
  Perhaps one of our readers will have more luck.

Update:  Cesar Crash provided a comment with this FlickR link of a Leaf Beetle in the genus Paropsisterna that looks like it is correct.
