plant bugs

(Neurocolpus spp.)

Overview

Neurocolpus is a relatively small genus of plant bugs. It occurs throughout the United States, southern Canada, Mexico, and Central America.

There are 19 Neurocolpus species worldwide, 13 species in North America north of Mexico, and at least 3 species in Minnesota.

Adults and nymphs feed on the flowers and developing fruits of their host plants.

Prior to 1934, all reports of Neurocolpus occurring in the eastern United States were recorded as Neurocolpus nubilus. This resulted in a very large range of host plants for that species. Since that time, at least four new species in the east have been separated from N. nubilus.

Little is known of the biology of Neurocolpus species. It is believed that most have a narrow range of host plants, limited to a few species or genera. The nymphs feed only on host plants. When the primary host begins to decline, mature adults disperse onto non-host plants.

Description

Neurocolpus species have many morphological features common to other genera in the subfamily Mirinae. They are best identified by details of the antennae, the mouthparts (rostrum), and the hairs (pubescence); by their overall size; by their geographic range; and by their host plant preferences.

Adults are 3 16 to 516 (4.50 to 8.50 mm) in length. The body is slender to moderately egg-shaped.

The first antennal segment is thicker and stouter than the second segment. It is covered with two types of hair-like processes (setae): flattened, scale-like setae; and slender, pale to black, unbranched, hair-like setae. Segment 2 is longer than segment 1. The setae on segment 2 are hair-like, unbranched, and lying flat (recumbent). Segments 3 and 4 are much more slender than segment 2.

The exoskeletal plate covering the first segment of the thorax (pronotum) has several small tufts of black, erect, stiff, bristle-like setae. It also has typical, unbranched, hair-like setae that may be erect, sub-erect, or reclining. These are intermixed with fine, silky, silvery or golden, hair-like setae.

Glossary

Pronotum

The exoskeletal plate on the upper side of the first segment of the thorax of an insect.

 

Pubescence

On plants: the fuzzy hairs on a leaf, bud, stem, fruit, flower, or other structure. On insects and arachnids: the hair-like processes (setae) on the body.

 

Rostrum

The stiff, beak-like projection of the carapace or prolongation of the head of an insect, crustacean, or cetacean.

 

Seta

A stiff, hair-like process on the outer surface of an organism. In Lepidoptera: A usually rigid bristle- or hair-like outgrowth used to sense touch. In mosses: The stalk supporting a spore-bearing capsule and supplying it with nutrients. Plural: setae. Adjective: setose.
