is the Oldest Insect Fossil?
The oldest identifiable insect fossil is a 390-million
year old bristletail, a primitive wingless insect
from the order Thysanura found in Quebec, Canada.
The insect fossil is remarkably similar to modern-day
silverfish. The first flights on earth were undoubtedly
made by insects!
Did Butterflies Live During the Era of
Fossils of butterflies are rare with the earliest
fossils from the early Cretaceous period, about
130 million years ago. The development of the
butterfly species is closely linked to the evolution
of flowering plants (angiosperms) since both adult
butterflies and caterpillars feed on flowering
plants, and the adults are important pollinators
was the Biggest Insect Ever?
Fossils of a prehistoric dragonfly (Meganeura
monyi) in the order Protodonata makes it the largest
insect ever to be found with a full wingspan of
30 inches and a body length of 18 inches. The
Meganeura dragonfly lived about 250 million years
ago until it became extinct at the end of the
What Type of Insect has Been on Earth
The oldest group of insects on Earth are the cockroaches,
particularly those in the Blattaria order, as
this species dates back 300 million years.
What is the Largest Living Insect?
The largest living insects are Giant Walking Sticks
from the (order Phasmida). This bug can grow to
up to thirteen inches in length making it surely
one of the longest insects in the world. The record
holder for the longest insect goes to a specimen
commonly found in Western Malaysia and Singapore
called the West Malaysian Pharnacia Serratipes
and it reaches an amazing length of twenty-two
inches. There are approximately 3,000 tropical
species of walking sticks, with only 10 species
living in North America.
Although principally tropical and Asian in distribution,
walking sticks are also found in the temperate
regions of Europe and North America. One species,
Megaphasma dentricus, is the longest insect in
the United States, attaining 7 inches in length.
The Malaysian Walking Leaf (Heteropteryx dilatata)
is another very large insect to add to that list.
Females of this species can be very large, up
to 6.5 inches long which makes them half an inch
short of being the longest insect. Framed walking
stick insects are available in a variety of species
for the discriminate insect collector.
What is the Largest Insect Egg?
The Malaysian stick insect (Heteropteryx
dilitata) lays the largest insect egg with the
egg measuring .05 inches.
