Support Your Local Pollinators


June is For Celebrating! 


There is lots to celebrate this month. Yesterday was Juneteenth, today is the Summer Solstice,  this week is pollinator week and this whole month is pollinator and pride month! It's a great month to celebrate and for this week and month I'll be highlighting pollinators

Why Pollinators are Important

Pollinators run the world. We have them to thank for our morning coffee and the jam on our toast. A whopping 80% of food crops grown for consumption depend on pollinators! Think apples, peaches, blueberries and one of my favorite things ever - chocolate. It's estimated that around 1 in every 3 bites of food we consume is made possible because of animal pollinators. In our natural ecosystems, 75% of plants are animal pollinated. Why do we need pollination? Pollination is the transfer of pollen from one flower to the other which will result in the production of fruit or seed. Pollination helps support and increase biodiversity and ensure plant communities survive. Plants that depend on pollination to produce seed face decline in populations and fertility without the support of pollinators. As I said, pollinators are truly running the world. 
Pollinators also just bring joy. I love seeing the first Monarch of the season or a little bee butt sticking out of a flower. I can count on them to brighten my day and by planting flowers I hope to do the same for their brief but important life.

How can we Support Pollinators?


Plant Something!

I won't go on a long tirade against lawns (but they just stink). A few reasons why lawns aren't good for the environment is lack of biodiversity, need to use chemicals, need for lots of water, and absolutely zero support for pollinators and wildlife. Having some lawn isn't the end of the world but with new developments popping up all over, trees and plants are taken out and replaced with lawns. The plants that are put in are typically not native plants or anything to support biodiversity. We can do our parts by having a garden that benefits not just us but animals as well. Even a small garden can help, heck even having pots of beneficial plants is playing a role to improve our planet. 
An example below is an educational pollinator garden I took from a sterile wasteland to a vibrant and diverse habitat. This little pocket of a garden on a 4 acre organic farm serves to educate the public and support wildlife. We also tried to do our part on the farm by planting rows of perennials that served to support the environment rather than just humans. 

A sterile environment is good for nobody

Lots of work done!

Natives Pack a Punch


Pollinators and plants have relationships that evolved over time. Some evolved together so much they are now in very exclusive relationships - the loyalty is admirable for sure! Monarchs and milkweed is a great example of this type of exclusive relationship. The monarch caterpillar exclusively feeds on milkweed and needs it in order to feed and develop into a butterfly.  Native plants are also adapted to our area and typically fairly easy to maintain and grow. Habitat loss is a great threat to native plants and wildlife and being able to ensure the survival of these species means we must continue to plant them!

Be a Good Host 


Natives are even more important to plant when it comes to supporting the early life of an insect. If you're thinking about ways to support wildlife learning more about host plants is a great start. A host plant supports an animal by providing either food or habitat. These plants in turn support the entire ecosystem by ensuring the insect will grow into adulthood and providing food (caterpillars) to other animals such as birds. Plants that are hosts do not just include perennials but trees, shrubs, vines and grasses as well! Did you know Oaks play an extremely important role in our ecosystem by hosting over 500 species of butterfly and moth caterpillars and providing food and shelter to wildlife? Native grasses also serve as host plants to several species of butterfly, are great habitats for bumble bees and provide food to songbirds. Milkweed as mentioned above is a classic host plant example but some other interesting hosts plants include Lindera benzoin (Spicebush) and Sassafras albidum, which host the Spicebush Swallowtail and Aristolochia (Pipevine) which hosts the Pipevine swallowtail.

Think about the Tough Months 


Early Spring, Late Summer and Fall are often difficult times for pollinators when it comes to food. It's important to plant a garden with varying bloom times especially when food becomes more scarce. Think about Fall when many of our Spring and Summer perennials are gone. Asters, Goldenrod, and Ironweed are a few examples of Fall blooming natives. 
Spring ephemerals are even more important to grow and protect when you think about how early they can provide food. Late Summer is tough on all of us - pollinators included! Plants like Joe Pye Weed, Blazing Star, Cardinal flower and Sunflowers bloom Late Summer into Autumn providing food at a tough time. 

Symphyotrichum oblongifolium (Aromatic aster) is a great fall blooming native for pollinators

Color, Color and more Color! 

Plant several different species in clumps to provide a diverse amount of food. And don't skimp on the color! Flowers evolved to have bright colors for a reason - to get pollinated! Purple, Violet and Blue are some favorite colors to bees. Red and Pink are hummingbird favorites. And for butterflies - who have the ability to see more colors than humans - Orange, Red, Yellow, Pink and Purple really get them going. Planting diverse types of plants - different heights, colors, and flower types - will attract and support a variety of pollinators in your garden. 

I went heavy on color at the Community Center - the more color, the more pollinators!

Fill the Voids...with Annuals


Annuals sometimes have a bad rep for being wasteful or having little impact on the environment. But many annual flowers, herbs and vegetables are also sources of food for pollinators. Including annuals in your garden adds variety and even more food. For example, squash have flowers that need to be pollinated to fruit and who better to do that than our native Squash bee? Squash bees are solitary bees that pollinate the Cucurbitaceae family - squash, cucumber, gourds and zucchini. 
Many members of Apiaceae family that are common in our gardens such as Dill, Fennel, Carrots, and Parsley are larval hosts to Black Swallowtail Caterpillars. These plants will flower as well providing food for the adult butterflies and other pollinators.  Don't be afraid to fill in with some annuals as they can really aid in feeding pollinators!

Praying with an Attitude

   

Let's talk about Mantids!


Does any insect trigger memories for you? For me, when I see mantises I think of being being terrified they would attack me as a kid. I was very convinced these alien looking insects were out for blood, their triangular heads moving slowly, following my every movement. Then WHAM! It jumps on me and goes after my fingers. Yeah - this never happened and never will. But boy was I convinced! Maybe my mom told me a tall tale about them so I wouldn't mess with them, just like my sister told me the stove would blow up if I touched the knobs - that one left me scared of stoves for a long time (sisters are great, am I right?). 

Sometimes it feels like I'm being watched... 

As an adult I don't feel worried a mantis will eat my fingers off - so glad I got over that one. Now, they just fascinate me like many insects do. I get so excited when I stumble upon one while working in the garden. The phone comes out and a photoshoot commences, the mantis just hanging on to the plant, still as always but watching, probably wondering what this crazy lady is doing. Young Julie would be shocked and maybe a little terrified to see Adult Julie willingingly picking one of them up. 

But which mantis is which? And why are some problematic now? 


The Basics


Mantids include insects in the family Mantidae, closely related to grasshoppers and cockroaches. They are considered beneficial ambush predators as they are helpful with pest management - although they are non-selective and will eat the beneficials as well. Mantids are fairly distinct with their unique front legs used for grasping prey, triangular heads and large compound eyes. There are around 2,400 species around the world (wow!) with most living in tropical areas, some in temperate. In the United States there are about 20 species. Eggs are laid in the Fall in frothy masses called an ootheca. You've probably seem one of these egg masses before while working in the garden or hiking. Mantids are generalist predators and eat a variety of insects and spiders, sometimes their own kind even (yikes). Females have even been observed eating the male while mating (double yikes).  While that behavior might be a little questionable  (ma'am, didn't anyone teach you it's rude to eat your mate?) there are many fascinating facts about mantids and some really interesting species! Did you know they are the only insect that can move it's head side to side and not move its body? Pretty wild! You'll often hear them referred to as 'praying mantis' as their folded front legs look like they are in prayer position, I imagine praying for their next meal ("Lord, send me a spider!").  Let's take a look at the commonly encountered species in Pennsylvania. 


Yes this is a mantis! The orchid mantis (Hymenopus coronatus ) is native to tropical forests in Southeast Asia. They are also often bred and kept as pets
 

Carolina Mantis


The Carolina mantis (Stagmomantis carolina) - our native mantis! A Carolina girl like me.  At just around 2.5 inches long, their small size makes them fairly distinct compared to the larger, exotic guys. Colors vary with this species as they are able to camouflage themselves well. Some are a mottled gray, some green and some brown. Color isn't the best way to tell them apart from the other common mantids we have. Check the wing length and  body size! The Chinese and European mantis have wings that extend all the way down their abdomen while the Carolina mantis has wings that do not reach all the way down the abdomen - they go about 2/3 down. They are much smaller than the Chinese mantis but may get mixed up with the European since the sizes are similar. Like all mantises, the Carolina mantis is non-selective with it's diet and will also feed on beneficials but the small size make them unlikely to take a whole bird down - we'll get into the bird eating with the Chinese mantis. Finding one of these in the garden always brings a smile to my face. 

At Chanticleer. The wings do not reach all the way down the abdomen.

Chinese Mantis 


The Chinese mantis (Tenodera sinensis) ended up in the United States the way many exotic species do - in the plant nursery trade. It was actually in the Mt. Airy neighborhood of Philadelphia where the  Chinese mantis was accidently brought over in the late 1800's.  The Chinese mantis is much larger than the Carolina mantis - up to 5 inches in length. Pretty big! And with that size comes their big but not so great reputation. Looking up this species of mantis will bring you to many articles about them being invasive (though they are not on the invasive species list). You'll see pictures of them munching on a Monarch and one horrifying image of a hummingbird in its grasp. Many people are now hunting down their egg masses and disposing of them. Though the hummingbird eating is rare and unnatural, it has definitely stirred the pot and upset many people. There is not a lot of research yet but it has also been said they are outcompeting and even eating the native mantis species and with their large size I wouldn't be surprised if a native mantis became their breakfast. Their eating habits make them a bit of a wild card in the garden but do they deserve all the hate? What are your thoughts? 

Chanticleer. The male is much smaller! 


My hobbies include holding random insects

European Mantis 

The European mantis (Mantis religiosa) is the one mantis I have no photos of yet - where are you hiding? The European mantis has a large and distinct dot on the inside of its front legs which distinguishes it from other species as well as being totally green in color. Their wings are also all green and reach down the entire abdomen. Chinese mantis wings also reach down the entire abdomen but only the forewings (top wings) are green. They are about 4 inches long as adults - a little bigger than the Carolina mantis and an inch or so smaller than the Chinese. As with the Chinese mantis, the European mantis made it's journey to the United States accidentally in the nursery trade - glad we finally learned to quarantine plants. They are generalist feeders as well but not much slanderous information about them was found as with the Chinese mantis.

It's conflicting to know that some of these species of mantis have a bad reputation now, as I find them all so interesting and beautiful. I encounter them often working in gardens and enjoy their presence.  I'm not going to go on a total smear campaign against the exotic species or lead an egg mass murdering spree but I will say it is good to be aware and understand the origin of insects you see often and how to deal with ones that are non-native. If you feel strongly about finding and disposing of an egg mass of an exotic species in your garden or while out and about, then you do your thing! As a community it is simply good to be able to identify an insect and understand different view points. 

I personally believe we have bigger fish to fry (or insects?) with our time and resources when we have the Spotted Lantern Fly and a long list of other species that have made it to the invasive species list before I'm telling everyone to go out and destroy ALL the egg masses.

What are your thoughts on mantids? Do you feel the exotic ones are a huge problem or have potential to become one? Any encounters with them? Share below!
