An example of a monarch would be Queen Elizabeth II of Britain.
Both a king and a queen are an example of a monarch.
Monarch
A constitutional monarch, is a monarch whose powers are limited by a constitution. An absolute monarch (for example Louis XIV of France) will rule without a constitution, investing all powers in themselves as a monarch with little or no bureaucracy, and few restrictions on his actions.
Migration
The decisions are the responsibility of the monarch, but usually the monarch has advisors. Talleyrand (France) was one of those advisors, for example.
The best-known example is probably the Monarch butterfly.
Monarch is an example of a word with the suffix "arche."
The best example of an absolute monarch would be Louis XIV.
The United Kingdom has one. They have a monarch and they have a democratically elected parliament. The monarch is the head of state. The prime minister is the head of government.
One example of a lepidoptera insect is the monarch butterfly. This is because the lepidoptera order consists of butterflies and moths.
The "minority of the monarch" is when the monarch of any given nation is too young to rule properly, so a regent is chosen to govern in the name and on behalf of the Sovereign until the monarch comes of age. Most monarchies have their own systems, but to take the example of the United Kingdom, the Regency Acts ensure that there is an appropriate head-of-state through a Regency on the account of the minority of the monarch or if the monarch is incapable of performing royal functions. In the United Kingdom, I believe the monarch has to be 18 or older to govern by themselves.
The monarch butterfly eats milkweed and is so bitter to the taste as a result that birds avoid it. The viceroy butter fly mimics the monarch (looks like it) and receives the same protection.
