Beginners Guide to Pollinators




Read the review by Kathy Keatley Garvey at the Bug Squad website, For Beginners, a Guide to Pollinators
So many flowers.  So many pollinators. So many floral visitors.
On every field trip, we see something new and different.
With so much interest in pollinators, it's good to see that biologist Beatriz Moisset has written a downloadable book, "A Beginners Guide to Pollinators and other Flower Visitors." It's meant for young adults and beginners.

Official State Insects

Did you know that most states have an official insect? Probably not. You may have heard of state birds and state flowers, or even state butterflies. But, who would have thought of state insects! Actually most states have an official insect, or, at least an official butterfly. Some even have both. Just for fun, try to imagine which insect you would select to represent your state. Take a few minutes before reading further or checking this complete list. Think harder; are you drawing a blank? I will tell you later my choice for the state of Pennsylvania.

If you picked the honey bee, you are in the majority. Seventeen states made the same decision, not a very imaginative one. That is almost half of all states with an official insect. Tennessee, not satisfied with two state insects, the firefly and the ladybug, added the honey bee as its official agricultural insect. Kentucky did the same.

The notion that the honey bee could represent a state surprises me because it isn't a native insect. Europeans introduced it to this continent in the 1600s. It is an agricultural species, not a member of the local wildlife. Tennessee and Kentucky seem to be the only ones that got it right when making it their official agricultural insect. It shouldn't be so hard to find a useful native insect to represent each state considering that there are thousands of them.

Seven states have chosen the monarch butterfly; not surprising considering that the monarch is so well known and loved. Actually three of those states (Minnesota, Vermont and West Virginia) picked the monarch as their state butterfly, in addition to their official insect. I wonder which is truly well known: the butterfly itself or just its iconic image. Most people can't tell a monarch from one of its look-alikes, the queen, the soldier, or the viceroy butterflies. In fact, many see a fritillary and think it is a monarch despite clear differences in pattern and size. Kudos to Kentucky whose official butterfly is the Viceroy! They really know their insects.

Where this list of official state insects gets amusing is when the "insect" in question refers to dozens or even hundreds of related species. The ladybug has been selected by six states ignoring the fact that ladybugs, better called lady beetles, include around 500 species, not all charming or beneficial. Did you know that a few species eat plants, rather than insect pests? They are pests themselves, like the Mexican bean beetle and the alfalfa beetle. Also, did you know that a couple of dozens were introduced from other lands? North Dakota deserves congratulations for choosing the convergent lady beetle. They, too, know their insects.

In addition to North Dakota and Kentucky, a few other states show their knowledge of insects, for instance, Maryland with the Baltimore Checkerspot Butterfly (Euphydryas phaeton). This handsome creature well deserves its name because of its checkerboard pattern. South Carolina chose the Carolina mantis, another brilliant choice.

I promised to tell you my preference for the state of Pennsylvania. The state insect is the firefly, not bad; but with 150 species of fireflies, later on it was narrowed down to the species Pennsylvania Photuris (Photuris pensylvanica). Did you know that some fireflies are diurnal and have no light?

I would choose a beautiful little metallic green bee. It is small and goes easily unnoticed to the point that it doesn't even have a common name. Its scientific name, Augochlora pura, means "magnificent pure green bee." The public may not know about this little beauty, but it can be quite common. Mountain mint flowers can act as magnets for this hard-working pollen gatherer. Recently I saw as many as a hundred bees on each bush of mountain mint in a garden with more than a dozen such plants.

Would you have any suggestions for the official insect of your own state?

Lady Beetles. Not all are Welcome in the Garden






Asiatic Lady Beetle (Harmonia axyridis).
It poses a threat to native ones and it is a nuisance
when it gathers in large numbers
in winter in human habitations
………
 As I discussed in Native Plants and Wildlife Gardens on July 7th, not all ladybugs or lady beetles are beneficial. Some have been introduced from other lands and create trouble for the native species. Moreover, the sale of lady beetles as biological controls deserves thorough examination. You may be spending money for nothing or, worse yet, doing harm rather than good (Ladybugs,Lady Beetles or Ladybird Beetles. How Good are They?)

 Here are a couple of lady beetles which will surprise you. Not all lady beetles feed on other insects. A few feed on plants and may even be pests. The Mexican bean beetle (Epilachna varivestis) is just as cute as some of the most beloved lady beetles. Sadly it feeds on beans, peas and other plants of the pea family. The only consolation is that it also likes to eat that dreadful Japanese invasive plant, Kudzu.

I also want to mention another pretty one, the Alfalfa Lady Beetle (Subcoccinella vigintiquatuorpunctata). It was introduced from Asia and feeds on alfalfa and an assortment of plants, such as bouncing Bet and campion.
