I don’t know what this bug is and I’m dying to find out. My curiosity is killing me. It’s a very tiny bug supporting a huge shell of some kind of wood shavings , if you will. Hoping for an answer!!

Spanworm

Spanworm

Dear Ruth the gardener,
This is an Inchworm or Spanworm in the family Geometridae, and larvae can often be very difficult to identify to the species level.  One of the most noticeable features on your Spanworm is the red color of the spiracles or breathing openings on the side.  We thought that might lead us to an identification, but alas, it did not.  Knowing the plant the Spanworm was feeding upon might help.  Though we can make out a leaf on the right, we cannot tell the identity of the plant.  If you can supply us with the plant, we might have better luck.

At first we thought this caterpillar was a tomato or tobacco hornworm, but it was too spiky. We found it in an open field, mid-morning on a 75* day in July. The property is on the middle peninsula of Virginia. We’re surrounded by brackish water (Chesapeake bay watershed), but there are many farms (mostly corn) in the area.

Dear Kelli,
Though there is no shortage on our site, we are thrilled to be able to create a new posting of the first Hickory Horned Devil of the year.  Each summer we get numerous identification requests for the largest, and arguably most distinctive looking North American caterpillar.  Despite its fierce appearance, the Hickory Horned Devil is perfectly harmless.  Hickory Horned Devils rarely leave the host trees (hickory, walnut and other trees) where they are feeding on leaves, but this large specimen is getting ready to pupate.  It will seek a location with favorable conditions and it will bury itself before metamorphosing into a naked pupa that will pass the winter with the adult Royal Walnut Moth emerging the following year.

Dear ?,
The moth and caterpillar are both the same species.  Thanks for providing such beautiful images of a Polyphemus Moth and a Polyphemus Caterpillar.  If you are able, we would love to include an image of the cocoon in the posting as well.  You can read more about the Polyphemus Moth on BugGuide where it states:  “Larvae feed on leaves of broad-leaved trees and shrubs, including birch, grape, hickory, maple, oak, willow, and members of the rose family.  Adults do not feed.”

I found this bug on a jalapeño plant this morning. It eat the entire top of the plant overnight. Maybe a giant luna moth?

Tobacco Hornworm

Dear Margaret,
The Luna Moth is not found west of Texas and Oklahoma.  We just finished posting an image of a Tobacco Hornworm like yours.  Your individual in Arizona is eating a jalapeõ pepper plant while the one in Los Angeles is eating the leaves of a tomato plant.

Tobacco Hornworm

Tobacco Hornworm

Dear Sarah,
There are two related, similar looking caterpillars that feed on the leaves and occasionally the fruit of tomatoes.  You have the Tobacco Hornworm,
Manduca sexta, the larva of the Carolina Sphinx, which according to BugGuide, can be recognized by:  ” large green body; dorsal ‘horn’ (usually curved and orange, pink or red) on terminal abdominal segment; up to seven oblique whitish lateral lines, edged with black on upper borders.”  The caterpillar of the similar looking Tomato Hornworm, the caterpillar of the Five Spotted Hawkmoth, can be distinguished from the previous, according to BugGuide, because:  “The caterpillar has eight v-shaped stripes rather than the seven diagonal stripes of the similar Tobacco Hornworm (larva of Carolina Sphinx). The horn is also straight and blue-black rather than orange, yellow red. Unfortunately many images of these caterpillars found on the internet are misidentified. “
