Long can Insects Live?
Aphids live for up to 3 weeks. Periodical cicadas
can live as long as 17 years. Many people know
periodical cicadas by the name: 17-year locusts
or 13-year locust", but they are not true
locusts - which are in fact a type of migratory
grasshopper; They are flying, plant-sucking insects
of the Order Hemiptera! The queen of a termite
colony may lay 6,000 to 7,000 eggs per day, and
can live for 15 to 50 years. Tarantulas can live
30 years. A queen termite has been known to live
50 years. However, some wood beetles can emerge
from wood where they live after as long as 40
years! The longest life span of any butterfly
is migrating Monarch butterflies (Danaus plexippus),
Mourning Cloaks (Nymphalis antiopa), and some
moths may live for up to 6-12 months.
What is the Shortest Insect Life?
Mayflies live for as little as one hour! Some
butterflies live in their adult state for only
a few days. For example: Copper butterflies and
Small Blue butterflies.
How Much Silk Comes from a Single Silkworm?
Each cocoon of a silkworm can produce a single
thread of silk that is about 1,500 feet long.
More than 25,000 cocoons are needed just to make
a pound of silk. The Asiatic silkworm moth (Bombyx
mori) has been so domesticated over the centuries
that it probably doesn't even exist in the wild
anymore after having been reared in China for
4,000 years. It takes roughly ten pounds of mulberry
leaves to enable silkworm caterpillars to manufacture
one pound of cocoons which can then be spun into
a silk thread more that's more than 100 miles
