Dog-day cicada

English
Neotibicen canicularis

Pages

Dog-day cicadas are large insects with highly characteristic shapes and bodies that are twice as long as they are wide. They are 27 to 33 mm long, with wingspans of up to 82 mm. Their bodies are mostly dark with green and black markings on the upper side of the thorax. The veins at the base of the long transparent wings are also green. Significant colour variations may be related to the geographic origin of different populations. The green form described above is the most abundant.

Masked hunter

English
Reduvius personatus

These black or dark brown bugs measure from 16 to 22 mm long. They have an elongated, oval shape and a small head with sharp mouthparts. They use this beak-like “rostrum” to spear their prey so that they can feed on it.

The nymphs resemble adults but are lighter coloured and have no functional wings. They generally cover themselves in dust, sand or lint similar in colour to their environment. The underside of the nymphs’ body is black or brown, like that of adults.

Small milkweed bug

English
Lygaeus kalmii

Pages

This red and black bug has a distinctive red X-shaped marking on its wings and a red band on the first thoracic segment behind its head. Its slender body is 10 to 12 mm long.

The nymph has a red or orange-red abdomen, with black spots appearing on it as the insect grows. The wing pads are black and become more pronounced with each moult.

Green stink bug

English
Chinavia hilaris

Pages

The adults in this species are 14 to 19 mm long. They have shield-shaped bodies, like all bugs in the Pentatomidae family. They are green, with orange edges, and a few dark spots on the edges of the abdomen. The base of the forewings is leathery, and the tip is membranous. These insects have piercing-sucking mouthparts.

The young bugs, called nymphs, are black when they hatch and turn green, yellow or orange as they grow. They resemble small adults, but without functional wings or reproductive organs.

Stink bugs

English

Pages

Pentatomids owe their name to the fact that their antennae are divided into five segments (from the Greek penta, or five). This characteristic is less obvious than their shield-shaped bodies, which has also earned them the name “shield bugs.” There is a triangle (scutellum) where the wings join. Their heads are generally small.

The shape of the mouthparts of these piercing and sucking insects depends on their diet. In herbivores, the first segment of the rostrum is slender and located under the head. In predatory stink bugs, this segment is larger and projects in front of the head.

Most of these insects give off a very foul odour when they are disturbed. They produce these repellent secretions from glands on the abdomen, near the rear legs.

Leaf-footed bugs

English

Pages

In southern Quebec, leaf-footed bugs are usually small, stocky, dull-coloured bugs. The membrane of their forewings is marked with parallel veins.

In tropical species, the tibiae on the hind legs are sometimes very broad and leaf-shaped, hence their common name of leaf-footed bugs.

When disturbed, some of these insects release a foul-odoured substance similar to that emitted by stink bugs, produced by glands on the thorax.

The adults are 10 to 20 mm long.
