Common lady beetles l.jpg

Common Lady Beetles


Beneficial attributes of all lady beetles l.jpg

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

Life of a malb l.jpg

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


Color variation of beetles l.jpg

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


Spot variation of beetles l.jpg

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

Good beetle nasty habit l.jpg

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

Key malb factoids l.jpg

Key MALB Factoids

  • Up to 20% of the beetles are 3 years old

  • 3 year old females can still lay eggs

  • Around 50% of over wintering beetles are male (50% are female)

  • MALB’s can fly when temps reach 500F; aggregation flights begin around 650F


Key malb factoids22 l.jpg

Key MALB Factoids

  • Beetles tend to orient toward tall(est) structure in the area, i.e., house, tower, top of a hill, etc.

  • Aggregations in structures tend to be correlated with wooded areas

  • Presence of a sex attractant or aggregation pheromone has not been identified for these beetles

  • Speculated that beetle feces or dead bodies attract live beetles to area


Malb faq l.jpg

MALB - FAQ

Q: Do they bite people?

A: They occasionally do bite. It feels like a severe pinch, but shouldn’t break the skin or draw blood.


Malb faq24 l.jpg

MALB - FAQ

Q: Do they carry disease?

A: No, but there have been indications that either their bodies, hemolymph, or feces can be allergenic.


Malb faq25 l.jpg

MALB - FAQ

Q: Where they were released from helicopters?

A: No. They were ground released at the various locations.


Malb faq26 l.jpg

MALB - FAQ

Q: Do the beetles reproduce in the attic or house over the winter?

A: No. Males and females spend the winter in diapause (resting); the females are unmated.


Malb faq27 l.jpg

MALB - FAQ

Q: Do the beetles feed on wood or other house materials when over wintering?

A: No, they rely upon fat stored up in their body to hold them over for the winter.
