This species is typically brownish-gray in color. The two juga meet and may even overlap each other. Size and range are useful in eliminating similar species.

As might be expected for a species that has been collected many hundreds of times, Brochymena quadripustulata has been found on a great variety of plants. Trees with numerous records include Apple and other fruit trees, Ash, Black Walnut, and various pines.

Adults are most commonly encountered in April and May, and again in August and September. The species overwinters in the adult stage and thus can be found under the bark of logs and dead trees in the winter months.

Brochymena quadripustulata is of mixed economic importance. It does feed on trees such as Peach, and occasionally on other cultivated plants. On the other hand, it also feeds on caterpillars and other larvae, including pest species.
