Found these in our garden on a dill plant, there’s about 10 of them and we don’t know what they are or if they will harm the plants. Thanks!

Black Swallowtail Caterpillars

Black Swallowtail Caterpillars

Dear Marissa
These are Black Swallowtail Caterpillars,
Papilio polyxenes, and they are sometimes called Carrot Worms or Parsley Worms because they feed on the foliage of carrots and related plants, including parsley and dill.  They will eventually mature into gorgeous Black Swallowtail Butterflies.

Hi,
I’m a teacher in Hong Kong and one of my students and I have discovered a sort of caterpillar on campus and we would like to know what kind of bug it is.
We are south of HK, near a beach. The weather is warm and muggy, verging on summer.

Possibly Brush Footed Butterfly Caterpillar

Common Mime Caterpillar

Dear Candice,
We believe this is a Caterpillar of a Butterfly from the family Nymphalidae.  We will check with Keith Wolfe to see if he can provide us with a species name.

Keith Wolfe provides a correction.
Hello Candice 老師 and Daniel,
Don’t let those fleshy projections fool you, Bugman.  This is actually an immature butterfly in the family Papilionidae, specifically a Common Mime (Chilasa clytia) . . .

. . . which is probably searching for a safe place to pupate.
Best wishes,
Keith

Thank you very much! There are indeed many butterflies around here.

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.

Hello,
We found a chrysalis tucked away in a lonely shoe about 3-4 months ago (Sept or Oct). A friend had left her leather dancing shoe under our couch, and when I picked it up, out fell this little guy. It was attached up near the toe by two silk anchors.
Sadly he fell quite a ways, I’m rather tall so he got the brunt of a 3 foot drop to our hardwood. The Chrysalis is currently hanging in a mason jar with ventilation, but I’m rather curious for more information about it. Thank you for your time!

Swallowtail Chrysalis

Swallowtail Chrysalis

Dear FC,
This chrysalis belongs to a butterfly, not a moth.  We believe it is a Swallowtail Chrysalis.  Most Swallowtails produce upright chrysalides, that are held in that position by a silken girdle.  This Tiger Swallowtail Chrysalis from BugGuide looks similar.

Hello bugman,
we just discovered this bug that looks like a reptile/caterpillar with a brown/greenish body with white on it & an orange forked tongue that’s on our little baby orange tree?

Orange Dog

Orange Dog

Dear Cyn & Tony,
This is the caterpillar of a Giant Swallowtail, commonly called an Orange Dog.  Caterpillars feed on the leaves of citrus trees, but they are not known to cause significant damage to a healthy tree.  The orange forked tongue you mentioned is a scent organ called the osmeterium that releases an odor that might help to deter predators.  Adult Giant Swallowtails are the largest butterflies found in Los Angeles.  This is a species native to the eastern portion of North America, but with the cultivation of citrus crops in the west, there has been a significant range expansion.  The Giant Swallowtail was first reported in Southern California in the 1990s.

Today while digging in the dirt in preparation for planting onions, we noticed this Anise Swallowtail Caterpillar munching on carrot greens.  Though we have grown carrots for ten years, and though Anise Swallowtails are relatively common in the area, this is our first sighting of a Caterpillar in the vegetable garden.
