Wisconsin Pollinator Newsletter-July 8, 2018
Enter To Win Save the Bees t-shirt
Wisconsin roadsides are largely devoid of native plants and the beauty they once engendered as we
travelled our roads. The WI Department of Transportation (DOT) has chosen to replace the natural
flora with non-native grasses and forbs.
Restore native flowers and shrubs along Wisconsin roadways. Ask the Department of Transportation
to stop planting non-native grasses.
Restore the natural beauty of our State by using native plants along roadways and
chance to win this t-shirt
. Contest ends August 31, 2018. Three shirts will be awarded.
Bee Nutrition: Pollen
Pollen provides bees with protein, minerals, lipids, and vitamins. All animals need essential
amino acids, which must be obtained externally and cannot be synthesized by animals.
Honey bees also need the same 10 amino acids as other animals. These amino acids are
obtained from pollen only, because honey bees do not have any other sources of protein.
Pollen collection by a colony ranges from 35 to 75 pounds per year. When honey bees are
provided with insufficient pollen, or pollen with low nutritional value, brood rearing
decreases and workers live shorter lives. Shortages of pollen during rainy seasons
can cause colony decline or collapse.
Pollen is collected either by pollen foragers, which specialize on pollen collection, or
nectar-foragers, which happen to be dusted with pollen. Pollen is brushed off the
worker’s body by the front and middle legs, and transferred to a special structure
in the hind leg called the cubicula, or pollen basket.
Pollen foragers unload their pollen by “kicking” the pollen pellets off their legs into
a cell, which often already has pollen in it, and then the pollen pellets are “hammered”
into a paste-like consistency by other workers. Due to the secretions added by bees,
the pollens in each cell go through a lactic fermentation. The main effects of
fermentation seem to be the reduction of starch, increases in both reducing sugars
and fiber, and reduction of ash and pH.
Attracting Butterflies: Host versus Nectar Plants
Since we’re talking butterflies, there are two terms you need to know, HOST PLANT,
which is the plant on which the eggs are laid and the caterpillars feed and NECTAR PLANT,
which are the primary plants they feed on.
If you want to attract butterflies to your garden, it's important to understand the host and
nectar requirements of the species you want to attract. There are some flowers that have
a broad range of appear to butterflies. Check out the Butterfly Garden Plan for additional ideas.
The most well- known of these is the MONARCH. The host plants for them are the
Common Milkweed and the Swamp Milkweed, while the one plant they prefer for nectar
is the Orange Butterfly Weed..
Field Thistles and Hollyhocks are the host plants for the PAINTED LADY. They
prefer Coneflowers and Tall Verbena for food.
Dill, Fennel, and Queen Anne’s Lace are the host plants for the EASTERN BLACK SWALLOWTAIL.
It enjoys Butterfly Bush and Orange Butterfly Weed for its food.
RoundUp: Is This A Good Choice for You?
RoundUp® is a convenient and effective way to control weeds in your yard. Whether
you want to remove dandelions from your lawn and clear a large area of unwanted plants.
But be aware that there is controversy around the use of this product. At least for the
short -term, RoundUp® degrades the soil community and it takes weeks or even months
to restore bacteria and fungal populations. Here are some of the concerns:
• RoundUp® appears to have an indirect effect on the soil
microbial function and structure in ecosystems.
• Research found a decrease in soil bacteria and diversity
of the bacterial community. Decreases in the abundance of these bacteria over the
long-term could impair the ability of the soil to perform certain functions.
• Research has also demonstrated that a Roundup
formulation (R450) was toxic to soil fungus.
What's the alternative? First, use RoundUp® sparingly and consider applying it with a
fine paintbrush. Boiling water will kill weeds along sidewalks and driveways. Finally,
when you do apply RoundUp®, apply compost to the area 24 hours after application
to begin the restoration bacterial and fungal communities.

In Wisconsin, there are chapters in Stevens Point, Door County, Green Bay,
the Driftless Area, Fox Valley, Kettle Moraine, Madison, Milwaukee and
many others areas in the State.
The interactive Spring Wild Bee Identification Guide
will help you identify the bees you
see in your community by their color, shape, size and habitat. You can
also find a link to download a PDF version of the guide.
The Spring Wild Bees of Wisconsin guide is designed to help you identify wild bees
commonly found in Wisconsin in the spring and early summer.
To begin, you can choose to identify bees using either picture matching or a
dichotomous key.. With picture matching, you will simply select the pictures that
look most like your bee. With the dichotomous key, you will be asked a series of
questions about your bee, which will help you identify the correct type.
