If you're an entomologist, an agriculturist, a gardener or an insect enthusiast, you've probably seen the life cycle of a lady beetle, aka ladybug: from the egg to the larva to the pupa to the adult.
You may have missed the pupal stage when the adult emerges--or mistaken the pupal case for something dead (what's that carcass?) or something regurgitated.
Fascinating to watch!
Lady beetles, from the family Coccinellidae, are beneficial insects (some 5000 species) that feast on aphids and other soft-bodied insects. Entomologists call them lady beetles because this insect is not a true bug.
Scores of lady beetles visit our little pollinator garden in Vacaville. They especially like the narrow milkweed, Asclepias fascicularis. Want to see a video on the life cycle? Watch The Stunning Life Cycle Of A Ladybug | The Dodo on YouTube.

Picture this during National Pollinator Week: five monarch caterpillars and assorted honey bees sharing tropical milkweed.
It was love at first bite. Or love at first sip.
The 'cats kept munching and the bees kept foraging. Neither species seemed interested in the other.
But the adult monarchs definitely showed more interest in the tropical milkweed (Asclepias curassavica), a non-native, than the other two species, both natives, that we planted: the narrow leaf (A. fascicularis) and showy milkweed (A. speciosa).
They laid eggs only on the tropical milkweed, and so far, have produced five caterpillars.
The score to date:
Tropical milkweed: 5 caterpillars
Narrow leaf milkweed: 0
Showy milkweed: 0
Reminder: Folks planting the tropical milkweed in temperate zones (like here in Vacaville,Calif.) must remove or cut back the tropical milkweed by winter. "A protozoan parasite of monarch butterflies, Ophryocystis elektroscirrha or OE for short, can travel with monarchs visiting the plants and become deposited on leaves," explains the Xerces Society for Invertebrate Conservation.
Yes, indeed. But meanwhile, we're witnessing untold sharing on the wildly popular tropical milkweed by not only monarch caterpillars but honey bees, syrphid flies, bumble bees, carpenter bees, leafcutter bees and sweat bees.
We gardeners and photographers are also drawn to the spectacular red, orange and yellow flowers that add both beauty and color to a cherished pollinator patch in the midst of the COVID-19 pandemic...and National Pollinator Week.
