Identification

This large, colorful insect is the most common soldier beetle in the Midwest.

Adults are to 9 16 long. The body is elongated, soft, and somewhat flattened. The sides are nearly parallel. The underside is black.

The forewings (elytra) are brownish-orange and loose. They are leathery and flexible, not hardened like on most beetles. They are long but do not extend beyond the abdomen. Each elytron has a black, elongated, longitudinal mark. The black mark is usually confined to the posterior half but sometimes extends the entire length of the elytron.

The thoracic shield (pronotum) is brownish-yellow and wider than long. It has a short, black cross band.

The head is black, large, and prominent. It is visible from above, not concealed beneath the pronotum. The antennae are slender, thread-like, black, and more than half as long as the body.

The legs are black, long, and slender. The end segment of each leg (tarsus) has 5 sections. The fourth tarsal segment is lobed.
