Lady beetles


Members of this beetle family are recognized for their characteristic dome shape. Brightly coloured for the most part, lady beetles have black spots when their wing covers are yellow, orange or red, and yellow or orange spots when their wings are black. The short antennae have little knobs on the end.

Lady beetle larvae are usually elongate and have brightly coloured spots or bands as well as spines and tubercles. Some larvae have been described as resembling tiny alligators.

Leaf beetles


Most leaf beetles are small – less than 1.2 cm long – but a few species can reach 2 cm. Their elytra (hardened wings) are often smooth and shiny, but occasionally have distinctive shapes or may be either ridged or pitted. They come in a variety of colours.

The legs are a distinguishing characteristic of these insects: the final heart-shaped segment, just before the claw, is bilobed. This segment is covered with special hairs that allow the beetles to walk along waxy stems and leaves.

Jewel beetles


The elytra (hardened wings) of these beetles often have a smooth glossy surface with a metallic sheen. The brilliant colours range from green to red, blue and yellow, with some species displaying combinations of colours.

Members of this family are recognizable by their torpedo-shaped bodies and heads that partially retract into the prothorax, making it look as though they are wearing a turtleneck.

Yellow mealworms

Tenebrio molitor

Adult yellow mealworms are shiny, sturdy, dark brown to black beetles and measure around 16 mm (14–18 mm) in length. They are the biggest insect pests to infest whole and ground grains. Males are usually smaller and slimmer than females.



Caddisflies look very much like small moths. Depending on the species, they range from 4 mm to 4 cm in length. They have long slender antennae and vestigial mouthparts that enable them to ingest liquid food only.

Two pairs of dark membranous wings, which are folded roof-like over the abdomen when at rest, are located on the thorax. The wings are covered with tiny hairs that give them a downy look.

The cylindrical abdomen usually tapers off to a pair of appendages in females and to at least two pairs in males.



Depending on the species, mayflies range from 2 to 18 mm in length, excluding the antennae and caudal filaments. They are often whitish or yellowish in colour.

Mayflies have vestigial mouthparts and are therefore unable to feed. The membranous and extensively veined wings are held vertically when at rest.

Mayflies have two to three long filaments at the tip of the abdomen. These have a tactile role, stabilize the insect’s flight and, together with the wings, help prevent joined mating couples from falling to the ground.

Bed bugs


Bed bugs belong to the Cimicidae family. This family is composed of more than 100 species that feed on the blood of birds and mammals.

Two species live exclusively off humans: Cimex lectularius, which lives mainly in temperate zones, and C. hemipterus (F.), which is mainly found in tropical areas.

Before eating, bed bugs are brown or yellowish brown. Once they have fed on blood, they become reddish brown and resemble small apple seeds. Their heads include highly specialized piercing-sucking mouthparts. Generally, the tip of the male’s abdomen is pointed and the tip of the female’s abdomen is rounded.



Depending on the species, these elongate insects either have four wings or are wingless. Their long antennae are nearly half their body length. They are easily identified by the well-developed cerci located on the end of the abdomen. Females have long, straight-sided, stocky cerci, while males have narrower and strongly curved cerci.
