LADYBUG.

Introduction.
THE ANIMAL I AM RESEARCHING IS THE LADYBUGS. I CHOSE THIS ANIMAL BECAUSE THIS LITTLE INSECT CAN PREDICT THE CLIMATE WITH ANANTICIPATION OF SIX MONTHS, WHICH HELPS THEM TO KNOW WHERE OVERWINTERING AND SEEK REFUGE.
THE SCIENTIFIC NAME OF THE LADYBUG IS COCCINELLIDAE. LADYBUGS ARESMALL INSECTS, RANGING FROM 1 MM TO 10 MM. A LADYBUG WEIGHS APPROXIMATELY 0.021 GRAMS. THE LADYBUGS ARE FOUND WORLDWIDE, IN ALMOST ANY TYPE OF CLIMATE, AND INWETLANDS. A LADYBUG CAN LIVE FROM ONE TO TWO YEARS, BUT THE LIFE CYCLE, FROM EGG TO ADULT, IS ABOUT A MONTH.

LADYBUGS ARE WINGED INSECTS (A TYPE OFBEETLE). WHEN THEY ARE NOT FLYING, THE FLIGHT WINGS ARE COVERED AND PROTECTED BY A PAIR OF MODIFIED WINGS (CALLED ELYTRA). WHEN FLYING, THE ELYTRA OPEN UP,ALLOWING THAT THE WINGS MOVE. THE AREA ABOVE THE ELYTRA IS CALLED THE PRONOTUM (IT IS PART OF THE THORAX). THE PRONOTUM FREQUENTLY HAS GRAYISH SPOTS ON IT. THEHEAD OF THE LADYBUG IS VERY TINY (AND FREQUENTLY CONFUSED WITH THE PRONOTUM).
THE LADYBUGS HAVE:
6 JOINTED LEGS
ONE PAIR OF ANTENNAE
AN EXOSKELETONMADE OF QUERATIN (A TYPE OF STRONG PROTEIN SIMILAR TO THE ONE THAT FORMS OUR HAIR AND FINGERNAILS)
A THREE-PART BODY CONSISTING OF THE:
* HEAD
*THORAX
* ABDOMEN

APHIDS, MEALYBUGS, MITES ARE WHAT LADYBUGS EAT. THEY MAY SUPPLEMENT THAT DIET WITH FRUITS AND VEGETABLES SUCH AS GRAPES, AS IN THECASE OF ASIAN LADYBIRD BEETLES. OR THEY RARELY MAY BE NON CARNIVOROUS, AS IN THE CASE OF THE LADY BEETLE [PSYLLOBORA VIGINTIMACULATA] THAT EAT MILDEW.
