The labybug, like all
beetles, undergoes a complete
metamorphosis, 1.egg 2. larva 3.
pupa 4. adult. The life cycle of the ladybug
is between four to six weeks. In the
spring the female adults lay a mass of
eggs The eggs hatch in two to five days.
The larvae that hatches from the egg is small
and long and has 6 legs. The newly hatched
larvae feed on aphids for up to three weeks.
As it rapidly grows, the larva molts (sheds
its skin) several times. After reaching full
size, the larvae attaches itself to a plant
leaf or stem.
The larval skin then splits down the
back, exposing the pupa. and then they enter
the pupa stage. The pupa is about the
size of the adult but is all wrapped up,
protecting the ladybug while the it undergoes
metamorphosis into its adult stage.
The adult ladybug emerges
about a week later. However, they
usually do not have their spots for their
first 24 hours of adulthood. There may be as
many as six generations of ladybugs hatched in
a year.
OUR
LADYBUGS
Day 1
Our ladybug larvae have arrived. They seem
to like their new home.
Day 7 Our ladybug larvae are now sitting quietly in a
head-down position. They are going into
the pupae stage. When we return to school
on Monday they will be in the pupae stage.
We may have adult ladybugs by the end of the
week.
Day 14 Our ladybugs have been in the pupa stage
for a week now. Our first adult emerge
today.
Day 21 We are feeding our ladybugs soaked
raisins. After we observe them for a week, we
will release them to the wild. LINKS
