48 Beetle BRITANNICA STUDENT ENCYCLOPEDIA
Many beetles produce light and sound to
attract a mate or frighten an enemy. They
make light by mixing chemicals inside
special organs. They make a high-pitched
sound by rubbing together two hard
body parts.
Beetles hatch from eggs. The newborn
beetles do not look like adult beetles.
Over the course of their lives, their
form changes completely. Their bodies
change in three stages: larva, pupa, and
adult. This process is called
metamorphosis.

Beirut is the capital of Lebanon, a country
in the Middle East. The city spreads
over two hills along the coast of the
Mediterranean Sea. Beirut is Lebanon’s
main port and largest city. It was once
the most modern city in the Middle
East. However, a war in the late 20th
century caused a lot of damage there.
Tourism, banking, and other services are
important to the economy. Trade
through the port also brings money to
the city. Other major industries include
printing and food processing.
Beirut is an ancient city. It has been
conquered, destroyed, and rebuilt a
number of times. Over the centuries it
was ruled by Romans, Christian
Crusaders, and Arabs. Beirut was part
of the Turkish Ottoman Empire from
the 1500s to the early 1900s. After
World War I (1914–18) the French
ruled Lebanon. They made Beirut the
capital. Lebanon became an
independent country in 1943. Beirut
remained its capital.
Groups of Lebanese Muslims and Lebanese
Christians fought each other in a
civil war from 1975 to 1991. During the
war Beirut was divided into two
sections—a Christian East Beirut and a
Muslim West Beirut. After the war the
city remained divided, but it began to
rebuild its damaged buildings and
economy. In 2006 the city was damaged
again in fighting between the Lebanese
Muslim group known as Hezbollah and
forces from Israel.
