Fossil records show that beetles were abundant during the Mesozoic meh·suh·zow·uhk period (about 200 million years before present). Beetles were flower visitors of the earliest angiosperms such as Magnolia and rose. Source: https://www.fs.fed.us/wildflowers/pollinators/animals/beetles.shtml
Beetle pollinators are attracted to flowers by the bright orange color. The beetles not only pollinate the flowers, but they mate while inside the flowers. A mutant version of the plant with red flowers becomes more common with the passage of time. A particular variant of the beetle prefers the red flowers to the orange flowers. Over time, these two beetle variants diverge from each other to such an extent that interbreeding is no longer possible. What kind of speciation has occurred in this example, and what has driven it? Sympatric speciation, habitat differentiation.
Ladybug is the official State Insect of Massachusetts
The ladybug was adopted as the official state insect or insect emblem of Massachusetts in 1974 (thanks to a campaign that began with a second-grade class in the town of Franklin). Because this insect benefits agriculture and delights children everywhere, Ohio, New York, New Hampshire, Tennessee, and Delaware also designate the ladybug as an official state symbol.
A ladybug can consume up to 60 aphids per day, and will also eat a variety of other harmful insects and larvae (including scales, mealybugs, leafhoppers, mites, and different types of soft-bodied insects), as well as pollen and nectar.
Also called lady beetle, ladybird, or lady fly, the most common variety of ladybug found in Massachusetts is the two-spotted lady beetle (Adalia bipunctata).
The nine-spotted Ladybug of New York is also in decline at https://statesymbolsusa.org/symbol-official-item/new-york/state-insect/nine-spotted-ladybug
Puerto Rican Insects are declining.
The date includes pollinators. 2 degrees Celcius has already impacted 60 percent of the insect animal pollinators. If it happens in the tropics, think what is happening here. How many bees and butterflies have you seen of late?
Some common butterflies that you will find in the New York State area include Cabbage White, Eastern Tiger Swallowtail, Monarch, and Pearl Cresent and Painted Lady.
Host plant for Pearl Cresent: Several species of smooth-leaved true asters such as New England Aster. The species overwinters in the third instar caterpillar stage.
This spring, May 2, the Pearl Cresent was here when the lilacs bloomed. The butterflies look for native plants as the host plant, including the New England Aster, to reproduce and to obtain nectar. I didn’t see any asters because it was early. Lilac is not native, but first, which usually happens before native plants are out and flourishing. There are two broods, one in May and the other in August. Source: https://libguides.nybg.org/c.php?g=654973&p=4597781
Cabbage white butterfly: Reproduces on Brasilia plants such as cabbage, broccoli, and Brussel sprouts. Yesterday, I saw the Cabbage white butterfly in someone’s garden plot. The butterfly was laying eggs between the leaves of a Brasilia plant. Check the leaves and lightly wash the plant leaves gently with soap and water, and gently hose down afterward.
Painted Lady and the Monarch Butterfly
Summer 2018 – The Saratoga Community Garden was abundant with Painted Lady. The butterfly, along with the Monarch butterfly arrived around the same time. It was migration time toward the end of August.
The Painted lady overwinters in the southern United States. The Monarch journies back home to the Oyamel fir forest in Mexico. Last year both species were drawn to the brightly colored zinnia flowers. The Monarch butterflies flew right to the red zinnia, which they can see.
Monarch Butterfly Update.
The butterfly has seen a significant rise in the winter species surviving the winter. It is estimated that over 100,000 Monarchs are on their way back up north. With the winter habitat down t less than 20 acres, it is remarkable that the Monarch can still turn around their 10 percent survival rate, at least at the moment. The U.S. Fish and Wildlife are watching the numbers to determine if the Monarch is now an endangered species.
