Ladybugs and their Life Cycle



Photo-observations of Ladybugs from larva to pupa to adult beetles



In mid-spring with the greening of the Great Basin Desert, strange tiny alligator-like creatures seem to appear when the Filaree plants begin to grow.  These colorful, fearsome, elongated insects that  cling to walls and scurry along walkways are actually the larval stage of Ladybugs.

Ladybugs are in fact small beetles, Coccinellidae, that only reach from 2 to 10 millimeters in size.  The Ladybugs or Lady Beetles were given their unique name as legend goes, when many hundred years ago European farmers prayed to the Virgin Mary for help to save their crops from a plague of insects. The tiny red beetles arrived in swarms and began devouring the pests, so they were appropriately named Lady beetles.  Lady beetles were introduced to the U.S. from Europe and became known as Ladybugs.

Ladybugs are not harmful to humans and are one of the most beneficial critters to have in the garden because they eat aphids, scale insects and plant mites.  As a defense mechanism and to ward off predators, the adult ladybug displays a vivid red shell.  If threatened small drops of blood with a foul odor are released from the leg joints.

Come spring, the female ladybug lays her eggs on the underside of an especially selected leaf.  In 4 to 10 days, the larvae hatch and begin eating any aphids or other appropriate insects.  They may also eat the egg casing and/or their siblings.

 The ladybug larva continues to grow and will shed the exoskeleton five to seven times in the larval stage.

Continuing to develop and between 10 to 14 days, the larva will find a stable structure and affix itself to begin metamorphosis into a lady beetle; this is the pupa stage of the ladybug's life cycle.

A hard shell protects the pupa during the 7 to 10 day transformation.

When the young ladybug first emerges from pupa, its body is soft and dull in color.  At this stage it is most vulnerable.

As the beetle develops into an adult ladybug, the shell will harden and become more vibrant in color.  The orange-red color of the shell is a defense mechanism that is perceived as a warning for predators to keep their distance.

The diet of ladybugs consists not only of small garden pests but also pollen from flowers and water from shallow surfaces.  

In defense of these beneficial garden allies, I have become much more conscientious with my insect and weed control.  A broom takes care of most unwanted creepy crawlers and a sharp hoe removes the weeds.  I get the exercise while the ladybugs do their work.

With El Nino still in the weather forecast, the Great Basin area of Northern Nevada is getting more rain, so follow my blog and check back often to see where my next photo-adventure takes me.

What an exciting and interesting photo-adventure this day has been.  I love it when I am drawn to an area and not knowing what to expect I get treated to new experiences.

Photography places me in the moment where I can share that moment in time. It becomes a life story as represented by my interaction with the scene. The happiness and beauty or the sorrow and strife; how I focus leaves a lasting impression that might touch the viewer on a spiritual level.

THE LADY BEETLE Harmonia axyridis



Gardening Friends

Early this spring of 2010 while weeding my yard, I noticed a large number of small alligator-like insects crawling all over the ground and plants. After taking photos of the creatures and "Goggling", I discovered that they were lady beetle larvae.



Lady beetles lay their eggs in small clusters on the protected surface of leaves and stems that are close to their food source of aphids. One Lady beetle may lay over 1,000 eggs during the three months in spring and early summer.


The larvae hatches from the egg by biting a hole in the surface. At this first stage, the larvae will have a gray elongated soft body, six legs and no wings. During the next three stages the larvae will continue to grow and shed the old skin, while it eats aphids and other garden pests. At the last and fourth stage, the larvae has almost reached the size of an adult beetle.
 
 
 
When it has eaten enough, it will attach itself to a substrate and molt into a pupa where it continues to develop into an adult lady beetle.
