Pollinator Week 2024

I have been working with European honey bees for almost 13 years now. Some of the things that I love the most are the challenges that present themselves. The dramas of the hive such as queens attacking their sisters, would be invaders being stung to death and then mummified, and the pushing out of the male bees at the onset of the winter for them to starve death are all fascinating. And of course, the sweet, sweet, honey reward. Of course, European honey bees are not native to the United States nor are they even close to our only pollinators. The first hive was brought over on the Mayflower and later spread throughout North America being called the ‘white man’s flies’ by the indigenous communities. 





Virginia is home to over 450 native bees that have co-evolved with our native plants tocontribute greatly to their pollination. They are for the most part not social like honeybees and have a wide range of interesting ways to raise their young independently witheach female making their own nests for their developing brood. Some bees dig holes inthe ground and line their nests with leaves or make a cellophane like substance. Othersuse hollow stems or burrows in logs, and bumble bees re-purpose old mouse burrows.They come in different sizes and colors ranging from bright metallics like the Sweat Beeto dull oranges, browns, and blacks like the Two-spotter Longhorn Bee. Perdita minimais the tiniest bee at only 2 mm in length and our biggest coming in at almost an inch, arethe Common Bumble Bees. None of our native bees make honey, only small packets offood for their young. But they make better pollinators than honey bees for the most partas they have evolved with the native flowers and have different length tongues and have different strategies, like the bumblebee who uses buzz pollination to shake the pollen out of flowers. But wait! You’re sitting and looking at your beautiful ox-eye daisies and you notice something that does not have the body shape of a bee…. Wasps, beetles, moths, butterflies, flies, and even birds pollinate flowers while trying to grab either that sugar fueled nectar reward, using the flower as a base to prowl and eat other insects, or by grabbing up some protein rich pollen. The stink horn cabbage’s bloom smells like rotten meat and blooms in February while the days are still frigid and couldn’t be pollinated by anything other than flies! Scientists are still trying to scout out and count the most likely thousands of pollinators other than bees. I believe I sometimes count as a pollinator as I walk through fields during the summer, brushing past flowers, eventually being covered in yellow from the head down. 


Without this network of a mostly invertebrate, flower loving community, we would be doomed to a life without 75% of our fruits, nuts and vegetables. Over 100 crops in the United States alone depending on pollination. And yet, in a short 5-year study (2008-2013), wild bees declined by 23% across the United States. All over the world, scientists are reporting staggering decline in insect numbers in general. Habitat loss, climate change, and pesticide use are all slowly working against these small but mighty beasts that keep our species going. Although one person, one garden can not reverse what is occurring in our ecosystem, we can do some things that combined, may be the literal life and death of a localized community of insects in your area. Planting native plants of all kinds that bloom at different times of the year allows access to food for these insects during all seasons. Reduce or eliminate pesticide use around your garden. Build brush piles and leave some areas wild. Additionally turning off your outside lights when you go to bed can reduce confusion for night flying insects. There are also a few citizen science projects that are already approved like Budburst and Bumblebee Watch to help count and monitor pollinators so scientists can monitor the changes and declines of our important insects. Either way, go out, find a flower or two, and sit in amazement as something so small that contributes something so important to us all!

Recent Herp Sightings at the Fell Residence

Not a day goes by at my place without a visit from some interesting wildlife!  
Here are some recent visitors from this spring...

This tiny guy must be one of this year's hatchlings.

I also saw two adult turtles in May.

Don't forget to submit any box turtle sightings to the Virginia Herpeteological Society!  


Lizards are a daily sighting here. Here are two of the most common:

This kinky fellow was checking out the bird house off the deck.  
Lucky for the birds, they had all recenlty fledged.

Amphibian Spring - Love In The Rain

By Brian Williams and Dr. Ariana Kuhn 


"It’s February, it’s dark, it’s raining – lets go!”   

While most humans may prefer a warm fire, a glass of wine, and a Valentine’s dinner, herpetologists are pulling on wading boots and rain gear, strapping on headlamps. and heading to the ditches and vernal pools with nets and cameras. So if you see some crazy folks wandering around in the woods on a rainy February night, don’t worry. It's just your local “herpers” out trying to catch the annual nuptial dance of the spotted salamander (Ambystoma maculatum).

The “Liebespiel” only takes place over a few nights in February and you have to be at the right place at the right time to see these magnificent spotted miracles performing their dance. Even if you don’t see the mating ritual, you might still be lucky enough to catch sight of a few of these impressive salamanders with two rows of bright yellow spots along their backs. Every spring, they migrate from the forest to wetland ditches and vernal pools to breed. Males usually arrive first, dropping spermatophores on small underwater vegetation where females will take these packets into their cloacas to fertilize their eggs and redeposit them on the vegetation in a sticky gelatinous mass. Each mass contains 100 to 200 eggs. The egg masses are quite easy to see, clinging to the underwater twigs with little black dots inside each egg sack (often seen together, wood frog egg masses and other salamander masses can look similar). The adults leave the pool after a few days, leaving their eggs behind. The larval salamanders hatch within a month or two and become salamanders in two to four months. The vernal pools are ideal sanctuaries for these eggs and larvae to grow, as they contain no fish predators. The best pools have lots of scuds and other macro invertebrates that the larvae feed on before they metamorphose, loose their gills, and begin the next part of their adult lives on land.

The first week of February saw major rains and it was evident by the road kills that the amphibians were taking advantage of the water levels in the ephemeral pools. Although we could not get out on this first rainfall event, several nights later we did manage to check out several locations and find not only spotted salamanders, but a few of the other amphibian harbingers of spring. The spring peeper (Pseudacris crucifer) is the call that most will recognize, sometimes you can even hear it through the rolled-up windows of your car as you pass by low lying areas with standing water. But this time of year you can also hear the raspy plunk of the wood frog (Lithobates sylvaticus), the resonating croak of green frog (Lithobates clamitans), and the cricket-like trill of the upland chorus frog (Pseudacris feriarum). The eatsern newt (Notophthalmus viridescens) are also common in some of these same locations this time of year, as they are doing their own underwater courtship dance.

Such a brief moment in time between egg deposition and when these “wetland wonders” head back underground for another year. They can live up to 20 years and return to the same pools each year, so it is important that we protect these sensitive areas.

Participating in early spring identification and monitoring of aquatic systems that support vernal breeding amphibians is a valuable resource to conservation, research, and ecosystem health. This data not only helps reinforce accurate geographic ranges and environmental preference of species, but also key information about the timing of biological events, such as breeding and development. Over time, threats like climate change could cause major shifts in these events, which could have serious implications for sensitive amphibians. Additionally, mapping out areas that are essential to many vernal breeders can benefit conservation and restoration projects that provide critical habitat to some of our less frequently seen, but incredible native species, like the spotted salamander.
