Luxembourg, one of the smallest countries in the world in area and population, is divided into three districts: Diekirch, Grevenmacher, and Luxembourg. These districts are further divided into 12 cantons and 106 communes. Twelve of these subdivisions are large enough to be labeled as independent cities.

Iphiclides podalirius - Despite its name, the scarce swallowtail butterfly is common throughout Europe, but their numbers have suffered a sharp decrease. This decline is attributed to the clearing of blackthorn bushes, an important food source for the swallowtail larvae. The chrysalids will take on either a green or brown color during the pupae stage for the purpose of camouflage. The larvae will form a green pupae before August when the leaves are green; after August they will form brown pupae to blend in with the decaying leaves.
