The Good Guys

 

Not everything that makes you jump is scary.

When you are sitting in your living room relaxing on your couch and something small and black crawls above you on the ceiling, then drops to the floor and skitters away, what do you do?  If you are my sister, you either jump onto the nearest table or grab a broom and go into attack mode (I have an absolutely hilarious story of a house centipede that visited my sister in the shower).  If you are my son or me, you take the moment to follow the little guy across the floor, teach your mom how to send a video on Snapchat, and thank the eight legged arachnid for its service.   

In my treks in the fields, I not only look for the pests that are harming the crops, I keep my eye out for—and find—critters that are helping the farmers.  These critters are called beneficial insects [although technically, they aren’t all insects—I know, I know; it’s just a technicality, but I just had to mention it].  Most of the good guys are predators.  That means they eat the pests that eat the plants.  Probably not the first thing you think about when you hear The Lion King’s “Circle of Life”, but it’s a mini version of that. 

Here are some critters that I have found in my travels that aid us in our production:

 

***************************************

 

Lady Beetle

This insect is commonly called the ladybug, although it is a beetle, not a true bug.  Most people recognize the different versions of the beetle, or adult form.  I personally love the larvae—they look like miniature gila monsters.  Both the larvae and adults love aphids, and that is usually what brings them to corn fields. 

 

***************************************

 

Praying Mantis

Praying mantises, or mantids, are amazing hunters.  They are known for their front legs, which are held upright together until used to grab their prey, and have triangular heads held on a flexible “neck” or elongated thorax.  

 

***************************************

 

Spiders

Spiders aren’t insects; they have two body sections and eight legs (insects have three body sections and six legs).  Not all spiders build webs.  Some jump on their prey, some build underground tunnels, some use water, and some even use their silk as a trip line.  

 

 

***************************************

 

Daddy Long Legs

Like spiders, daddy long legs aren’t insects, but they aren’t spiders, either!  They are arachnids (and so are spiders) but are called Harvestmen, so are kind of like cousins to spiders.  Their mouth parts are actually closer to a crabs, so they are omnivores—eating prey and “garbage”—and their legs can break off in sections if they are threatened. 

 

***************************************

 

Stink Bug

I’m sorry this photo isn’t great, but these guys just don’t pose well for a photo.  Most stink bugs—and yes, they are true bugs—are pests.  That is, they suck the juices out of plants.  We as agronomists have treatment threshold levels for them just like any other pest.  However, there are some stink bugs who prey on other insects, like this one that I found snacking on a thistle caterpillar in a soybean field.  The nymphs usually eat the same thing as the adults but they may look a little different from their parents. 

 

***************************************

Lacewing

I don’t personally have a photo of this one, and it actually isn’t the pretty adult that we have to thank for the benefits of predation.  The green fly-like adult with lacy wings (called a net-winged insect) feeds on nectar and pollen.  The larvae, sometimes called aphid lions, are clever huntsmen who look similar to lady beetle larvae (without the orange coloring).  They have been known to “dress up” in lichen and dead aphids to disguise themselves in order to get close to a meal! 

 

***************************************

 

So the next time you see something that crawls and you have the instinct to jump, take a deep breath and realize that they are just doing their job, too—good guys keeping your crops safe!

College Chemistry Memories

 

I remember Radiator Hall.

I remember thinking the windows are so small, how can they let the light into the chemistry labs above?

I remember walking into a lecture hall for the first time, the seats stretched out before me, rows and rows of hard plastic and wood beckoning, facing a man that looked both tiny and tall at the same time.

I remember Dr. Carr, who taught me that if you loved someone, you would brew their coffee starting with cold water because the water would be cleaner and there would be less impurities dissolved initially into it.

I remember seeing Dr. Carr always in striped button-down shirts and a bow tie in my mind even though I’m sure that’s not all he wore, with wire rimmed glasses and short light brown hair, almost blonde.  I don't even know if he wore glasses or what his hair color was, but that is how I remember him, these many years later.  

I remember the sticks and balls of organic chemistry molecular models, discovering the intricacies of how the smallest particle of something is put together, how that organization creates properties that makes each piece of matter behave the way it does, freeze and boil and move and bond and react and look the way it does, make it what it is.

I remember the feeling of seeing my preschool sweetheart for the first time in so many years as I walked out of the lecture room after class one day, realizing it had taken college to bring us back together, that we hadn’t seen each other since we were five years old, where holding hands meant going steady and all was innocent and I didn’t know the meaning of hurt in the world and even as my eyes brightened and we talked and reconnected, how little I knew then at twenty of the world than I do now and how I would like to go back and warn myself of what’s coming, what’s out there, what’s yet for her to encounter in this big world she looks at so trustingly yet, walking out of that lecture hall and into the sunlight, holding her hand above her eyes to block the glare.

Funny Looking Critters in Your Field

 

A repost of a fun blog.....

WHAT IS THAT???!!?!?!

That thought has crossed my mind as I scout crops, when I accompany my son fishing, and as I walk outside along my favorite trail.  I have received that question from producers after I’ve been in their fields.  (And, frankly, insects have always fascinated me.  I wanted to be an entomologist in grade school when all the other girls were dreaming of being fashion designers! ha!)

There are some very interesting looking critters out there!

I will focus on insects in soybeans because that is where I’ve been spending the most of my time when I’m outdoors lately.  Most of the time, these guys do munch on leaves, but they aren’t at a distribution and concentration intense enough to cause worry or warrant treatment; they are either an annoyance to tolerate or novelty to be curious about.  Once in a while—like in 2018 with the thistle caterpillar—an unknown phenomenon creates an unusual proliferation of a certain species, and treatment is needed before the critter eats your livelihood. 

Without further ado, let me introduce to you some peculiar looking creatures.

Green Cloverworm

This insect is almost neon green and has two white “racing” stripes down its sides.  The green cloverworm is the larvae for a bland brownish moth.  When you touch or bother it, the larvae wiggles around.  The soybean looper looks similar, but has one less set of legs in the middle of its body, and it walks in a “loop” like an inchworm. 

Japanese Beetle

This insect is a beetle with a copper colored body and shiny green head.  Its antennae are feathered, and it has six white tufts on each side of its abdomen.  When it feeds on leaves, it doesn’t eat the veins, creating a skeletonized or lacy look.  It also likes corn silks.  They tend to hang out together, so you can find these guys in groups, climbing all over each other.  Japanese beetle larvae are white, c-shaped grubs with orange-brown heads. 

Silver Spotted Skipper

This insect is the larvae to a brown butterfly with a silverish-white spot on its wings, hence the “silver spotted” in its name.  It has a distinctive looking larvae that turns many heads, with the light green body, dark brown head, and orange “cheeks” or “eyes” that make it easy to identify. 

Thistle Caterpillar

This insect is the larvae to the painted lady butterfly, whose wings are a decorative orange, brown, and white.  This year, I’ve heard lots of comments about people seeing these butterflies in swarms, and picking them out of the grilles of cars in great numbers.  The small larvae are darker, almost black, with small “thistles” or spikes on them.  As they grow, they use webbing to wrap themselves in the leaves that they eat, creating a safe “home”.  Here, their fuzzy brownish black heads work quickly to eat the leaves, leaving lots of big black frass (a cool name for poop....or a rock band.....) as they grow into more colorful, spikier caterpillars. 

Gorgone Checkerspot

Okay, I’m not completely sure about this one—I found it south of Wahoo, Nebraska on a sunflower leaf.  But the closest I could find was the larvae to a gorgone checkerspot butterfly, who does like sunflowers and is found in our area.  He was kind of cute and was posing so beautifully that I just had to take his photo. 

Soybean Gall Midge

This one is so tiny there is not a great chance you’d actually see these guys in the field.  But their damage is so terrible they kill the entire plant when the larvae burrow into the base of the stem.  They’re cool because they are a newly discovered species, and I just confirmed them in one of my fields.  So, yeah, this is my photo, and these guys are only known to us for a couple of years now.  They are the orange maggots to a striped midge fly that’s equally as tiny as its larvae. 

Thanks for reading!

Why I Don't Suicide

 

Facing the truth isn’t always easy.

The truth about my mental illness is that with it come thoughts of suicide.  I didn’t choose my illness, and I didn’t choose my brain.  What I can choose is what I do about those thoughts.

Sometimes I don’t do it

because who would take my cat?

Sometimes I don’t do it

because my kids are too young

to sort out my stuff just yet.

Sometimes I don’t do it

because I don’t have the energy.

Sometimes I don’t do it

because I don’t have the brain power

to come up with a plan.

Sometimes I don’t do it

because I couldn’t afford the hospital bills

if I failed.

Sometimes I don’t do it

because I don’t want to have to

explain it to everyone.

Sometimes I don’t do it

because I don’t want to pass my debt

on to others.

Sometimes I don’t do it

because I don’t want others

to have to see the pain I truly am in.

Sometimes I don’t do it

because I can’t

explain it to anyone.

Sometimes I don’t do it

because I can’t afford the therapy.

Sometimes I don’t do it

because I tell myself

I can handle it for just one more day.

Sometimes I don’t do it

because I can convince myself

the voices are monsters in my head

telling me the wrong things.

Sometimes I don’t do it

because my cat comes up to me

and nudges me in a way

that I know he is saying he loves me.

Sometimes I don’t do it

because someone calls or texts

just to say hi.

Sometimes I don’t do it

because the piano music I’m playing

speaks to me in a way that says

just hold on.

Sometimes I don’t do it

because a high school classmate

posts a message describing

their own struggles

and I know I’m not the only one.

Sometimes I don’t do it

because I find a message

my son left a long time ago

on a notebook for me.

Sometimes I don’t do it

because I know my daughter

saved my life once upon a time.

Sometimes I don’t do it

because I can journal my way

through it.
