I bought a pepper tree bonsai and I found this caterpillar attached to it. I believe it is a swallowtail caterpillar but I don’t know what variety. I was hoping to find out what is was since I want to care for it. Can I feed it lemon leaves instead of my poor bonsai?

Probably Giant Swallowtail Caterpillar

Probably Giant Swallowtail Caterpillar

Dear Meena,
This sure looks like an Orange Dog, the caterpillar of a Giant Swallowtail  According to BugGuide:  “Larvae feed on leaves of plants in the Citrus family (Rutaceae), including Citrus (Citrusspecies), Pricklyash(Zanthoxylum species), Hoptree (Ptelea trifoliata), Rue (Ruta graveolens), etc. Adults take flower nectar from a variety of herbaceous plants and shrubs.”
  We do not recognize your particular Pepper Tree and we would be curious to learn if it is in the citrus family.  You can try to feed your caterpillar leaves of an orange tree, but if it rejects those leaves, you may need to return it back to your bonsaii.  Caterpillars are not like dogs or pet fish.  They do not immediately begin eating if food is placed in front of them.  You may need to transfer your caterpillar to a citrus tree to see if it will accept the leaves.  Though lemon is a citrus tree, we cannot recall getting any reports of Orange Dogs feeding on lemon trees, but we have gotten reports of them feeding on lime, tangerine, grapefruit and the always popular orange tree.

Subject: Caterpillar found on my Chili plant
Location: Gauteng, South Africa
April 26, 2016 12:54 am
Hi there, I found a huge caterpillar on my chili plant and tried to google it and find more information about it. I found some images that relate to the one I have – It looks like a Laurel Sphinx caterpillar, but the region and habitat it is usually found in does not correspond with mine.. So I am not sure what it is. Can you please identify this for me?

Death's Head Hawkmoth Caterpillar

Death’s Head Hawkmoth Caterpillar

Dear M Kruger,
The reason your individual resembles the Laurel Sphinx Caterpillar is that your Death’s Head Hawkmoth Caterpillar is in the same family.  Caterpillars of the Death’s Head Hawkmoth are one of our most common identification requests from South Africa.

We found this along a trail in eastern Washington. It was as burrowing a hole in the dry dirt. I tickled its tail with a piece of grass and it turned around, half in and half out of the hole, as seen in the pic. About 3-4 inches long, as big around as my pinky finger.

Pacific Green Sphinx Caterpillar

Pacific Green Sphinx Caterpillar

Dear Jerry,
We are very excited to post your image of a Pacific Green Sphinx Caterpillar,
Arctonotus lucidus, which we identified on The Sphingidae of the Americas site.  Caterpillars of Sphinx Moths are usually easy to identify because they have a caudal horn, but some species lose the horn and only a caudal bump remains, and it is thought to afford some protection as it resembles an eye.  Though we have several images of adult Pacific Green Sphinx Moths on our site including this individual from Lyle, your caterpillar image is a first for us.  David Wikle is quoted on The Sphingidae of the Americas:  “and in the fifth [instar], the ‘eye of God’ is pasted on its arse and the horn is replaced by a raised area like Xylophanes or Eumorpha larvae.”  The larva is also pictured on BugGuide.  Since it was digging in the dirt, and it was quite large according to your description, we can deduce it was going underground in preparation for pupation.  We are going to copy Bill Oehlke as your image is so stunning, he may request permission to post it to his own site.

Location: Florida near pensacola, cantonment. But in a country part called Molino

I was sitting with my mother in our barn in cantonment. when I noticed (What i thought was fuz,) until it started moving. I have never seen anything like it, (Nor had my mom,) and i wanted to know more. It had to large thick, black antenaes. And one identical anteanae like tail. Conecting the anteanaes/tail was a black line down the middle, with little yellow hair covering the sides. It had an orange like headband, and two small red dots near its hind end. What was peculiar was the 4 white dots on its back, with a spiky black line coming out of each. Please help. We have many animals around our farm and would really like to know this type of bug, and if it is dangerous. Thankyou.

Whitemarked Tussock Moth Caterpillar

Dear Aden,
This is a Whitemarked Tussock Moth Caterpillar,
Orgyia leucostigma, and according to BugGuide:  “CAUTION: Avoid handling the caterpillar, as its hair is known to cause allergic reactions, especially in areas of the body with sensitive skin (e.g. back, stomach, inner arms). Seek medical treatment if a severe reaction occurs.”

Hello, hope you are both well.
I discovered this larva living inside one of the blooming apple-blossom amaryllis plants. Its abdomen end looks remarkably like a snake’s face to me, and its body also resembles a bird dropping when curled. It curled up when I moved it gently to the petals, and when moved back it resumed its head-down, posterior snake-face-showing stance. It has gold iridescent spots along lateral (subdorsal?) lines.
As you can see, it’s eating itself out of house and home. 😀
I tried to match it to known moths and butterflies in our county, but had no luck.
Lots of rain this week, upper 60’s and cloudy.
Thank you!

Cutworm

Cutworm

Hi Ellen,
We believe this is a Cutworm, the caterpillar of an Owlet Moth in the family Noctuidae.  We have a difficult time distinguishing different species as so many caterpillars in this large family look so similar.  You can try browsing BugGuide to see if you find any likely candidates.  Many species are not terribly particular about what plants they feed upon, which complicates identification.
