    3. Beneficial attributes of all Lady beetles Adults & larvae are generalist predators Feed on aphids, scale insects, mites, and other insects (some pollen & nectaries) All of the above pests damage agricultural crops, home, garden, and landscape plantings One form of biological control MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.

    7. MALB Adults Eggs to Adult ca. 30 days More diversity in color, spotting patterns and pronotum “M” marking.More diversity in color, spotting patterns and pronotum “M” marking.

    8. Life of a MALB… Spring-Awake from winter nap (diapause), actively move from shelter to outside Summer-Find food, find a mate, reproduce. There may be several generations per year with a larger proportion of later generations predisposed to over wintering. Fall-Triggered by shorter days and cooler temps., aggregation behavior toward structures begins on warmer days, diapause

    9. Color variation of beetles Red color due to high quality of food eaten as larva, i.e., lots of tasty aphids Yellowish color due to fewer aphids consumed but more pollen as a larva MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.

    10. Spot variation of beetles More spots, lower temperature and a longer duration of pupa stage Fewer spots, higher temperature and a shorter duration of pupa stage MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.

    17. Good beetle, nasty habit In Asia, they over winter in cracks and crevices of rock faces and cliffs In America, where rock faces and cliffs are not readily available, they congregate and over winter in houses and other man made structures MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.MCALBs collected using the vacuum cleaner with a half hose inserted in the tube.
