Just wanted to share these photos of a Red Spotted Purple caterpillar that was on my wild cherry tree. My husband got me the tree so that I could have the butterflies but we get very few of them. Their survival rate is low on our property due to so many predators. For protection the next ones to show up are going into the habitat with cuttings . They do become gorgeous butterflies.

Red Spotted Purple Caterpillar

Dear Elizabeth,
Thanks so much for sending in your images of a Red Spotted Purple Caterpillar.  We agree that the Red Spotted Purple is a gorgeous butterfly, and sometime back we waxed philosophically that it might be the prettiest North American butterfly.

Hi! I believe I also have an Elephant Hawk Moth larva/caterpillar in my yard – I took these photos last week & compared it to the one posted on August 7th from BC and they appear to be the same.

Yellow-Banded Day Sphinx Caterpillar

Dear Sandy,
While there are some similarities between your caterpillar and the Elephant Hawkmoth Caterpillar, that is a European species that has been introduced to the Pacific Northwest, and to the best of our knowledge, it is not found in Ontario.  Your caterpillar is in the same family, the Hawkmoth or Sphinx Moth family Sphingidae, but it has the unusual characteristic of lacking a caudal horn in its final instar, and possessing a caudal bump where the horn has been shed.  Your caterpillar is a Yellow-Banded Day Sphinx,
Proserpinus flavofasciata, and we verified its identity on BugGuide and Sphingidae of the Americas. where it states ” Larvae feed on willow weed (Epilobium) and possibly thimbleberry (Rubus parviflorus).

Elephant Hawkmoth Caterpillar

Dear PetrH,
This is an Elephant Hawkmoth Caterpillar,
Deilephila elpenor, and according to Learn About Butterflies:  “The caterpillar is brownish-grey, marked with a network of fine dark lines, much like the folds in the skin of an elephant’s trunk. When it walks, the caterpillar habitually sways the front segments from side to side, again reminiscent of the movement of an elephant’s trunk. The anal segment bears a short horn. The first two abdominal segments each bear a pair of pink and black eye-like markings. If the caterpillar becomes alarmed, it retracts its head, which compresses the thoracic segments and causes these ‘false eyes’ to expand. This gives the caterpillar a snake-like appearance, which presumably acts as a deterrent to predators.”

Gallium Sphinx Caterpillar

Dear Adrianna,
This is a Hornworm, the caterpillar of a Sphinx Moth in the family Sphingidae.  According to Sphingidae of the Americas, there are not many species found in Alaska, and we are quite certain because of the black color and red horn, that this is the Caterpillar of a Gallium Sphinx,
Hyles gallii.  More information on the species, also called the Bedstraw Hawkmoth, can be found on Sphingidae of the Americas. 

Thank you very much, the only thing we couldn’t see was the spots and I think that was because it was so dusty.

Also when we touched it with a stick it curled up and stuck the horn out, is that what it does?

If they feel threatened, many Caterpillars will curl up.

Found this little guy (ca 3cm) wandering the road near my house today and wondering what he is/what he’s going to be. Have found a lot of similar caterpillars online in the stinging slug variety, but none that match him perfectly.
Can you help identify him for me?

Stinging Slug Caterpillar

Dear Nina,
This is a Stinging Slug Caterpillar in the family Limacodidae, and as its name indicates, it is capable of stinging if it is carelessly handled.  We have found matching images on the internet with two different genus names.  This FlickR image is identified as
Latoia consocia, and JP Moths identifies it as Parasa consocia.

Hi bugman! My family and I went out for a walk and found this little guy hanging out on a leaf. We though you might like to have this photo!

Paddle Caterpillar

Dear Kristina,
First we need to commend you on your correct identification of a Paddle Caterpillar,
Acronicta funeralis.  The first time we received an image of a Paddle Caterpillar many years ago, we tried unsuccessfully to identify it.  It is quite a distinctive looking species, and not easily confused with any other caterpillar.  Your image is especially beautiful.
