Carphophis amoenus
Identification · Harmless

Identification

Brown above, pink below, shiny enough to catch the light, and the most committed burrower on this list. Most people who find one assume they have turned up a large earthworm.

Field Note

Held in a hand, a wormsnake presses the hard tip of its tail into your skin to lever itself forward, and people report being stung. It has no sting and no venom; it is trying to burrow through your palm.

Told Apart

What it gets mistaken for.

The short version

Two other small brown snakes share the same rock. The belly settles it every time.

Smooth EarthsnakeSame habitat

A plain cream belly with no contrast. The wormsnake's pink belly stops in a hard line against the brown back.

DeKay's BrownsnakeSame size

Keeled scales and a dark streak on each side of the head. The wormsnake is smooth and blank-faced.

An earthwormThe usual outcome

Scales, a visible eye and a tail that tapers to a point rather than a blunt end. Worms also do not move in an S.

Encounter

When you meet one.

What it does

It tries to burrow. Into soil, into leaf litter, into the gap between your fingers.

Digging the bed

Move it to shade.

Sun and dry air kill this animal fast. Set it under the nearest log or leaf pile rather than on open ground.

Move to cover
It presses your hand

That is not a sting.

The tail tip is a digging brace. There is no stinger, no fang and no venom anywhere on this animal.

No action
In the pool

Net it out.

They fall in and cannot get out. A net and a damp shaded spot is the whole rescue.

Net it out
Under the tarp

Leave the tarp.

Sheet cover left flat on damp ground is prime wormsnake habitat and costs you nothing to keep.

Replace cover

Pack it. Print it. Pass it on.

Most snakes killed in Williamson County are killed by someone who could not name them. Send this to anyone who gardens, hikes, keeps a woodpile, walks a dog off the greenway, or has a teenager who reaches into things. That is most of the county.
