Afton State Park: Covered in BEES

Finn and I went over to Afton State Park, another metro-adjacent Minnesota gem. They were having bee activities, where you could learn all about bees and make a bee craft. Pipe cleaners and tissue paper to the rescue! As bees, and other pollinators, have been the talk of the environmental world lately due to their apparent decline and phenomena such as colony collapse, I thought this would be a good learning experience for both of us. We have many pollinators in our garden, including honey bees, but our butterfly population was almost nonexistent this summer.

As with much of the non-human natural world, it's easy to put our own cultural biases and observations on top of them, so it won't surprise you to know that I did some mumbling when she said that the Worker bees, who are all girls, do all the work, and can sting. Yeah, it's no wonder they sting, slaving away while the drones, well... The Queen lays all the eggs, and the Drones, who are male, are sex slaves. No stinger. Which is helpful in a sex slave. In the fall, Workers block the Drones from the hive, and they die. (Insert snarky comment here.)

It won't surprise anyone to know that if flowers don't have bees and other pollinators, they don't grow. Other pollinators are wasps, hornets, hummingbirds, and butterflies. Wasps differ from bees in that they don't have hairs, their wings are longer, and their bodies are longer. Also, honey bees can only sting once and then they die; wasps can sting many more times, as we learned to our misfortune one summer and fall when they were nesting under our siding and repeatedly getting into the house.

Currently, honey bees are under threat from colony collapse, mites, fungus, pesticides, and the vast swaths of agricultural monocultures like corn and soybeans that blanket miles and miles of the heartland of the United States.

This was set up at the upper picnic area, and you could come at any time during the designated time frame to learn and make your crafts. Near the parking lot and the picnic area is a nice meadow, and we walked through it looking for butterflies and other insects. We did see a few monarchs and numerous dragon flies. At the beach, we saw common blue butterflies, which over-populated my youth to the point that they became mundane, but now, I rarely see them, so this was a treat.


What you should know: There are pit toilets at the upper picnic area, where this event was staged. They are a few yards down the trail. In them, you can see numerous spider and spider-adjacent species.

There are trails and a beach, but the beach is quite a walk if you have a small child who will refuse to walk after a time. Make sure you have a printed map with you because the signs on the trails were rather confusing, and I wound up making a wrong turn that ended with me walking way too far, eventually in the glare of the hot sun, carrying almost forty pounds of whining child on my shoulders.

Fort Snelling State Park: Storytime & Spiders

I have to say that while Finn does not mind having the lady rangers to himself, come on, caregivers! We were the only ones here again.
This event happens every Monday morning, and you should be here. Indoor story time is for winter. This week, we learned about what to do if you should find a baby Great Horned Owl in your backyard. Personally, I found most of this story to be implausible or all-too-convenient (baby owl is found by the children of a wildlife rehabilitator), but we definitely learned from it, and Finn found it interesting.

Later, after we hit the beach and the playground, we attended a spider talk, and there were other people present for this, which was nice. First we had a presentation from Ranger Amie inside the visitor center, and we found out:

-Birds eat spiders
-A black widow bite will make you sore all over, but you won't die.
-Mites will attach themselves to spiders and feed on them.
-Spiders eat spiders.
-Wasps eat spiders and will lay their eggs in them.


-Spiders eat mosquitoes, which makes them heroes and heroines.
-All spiders have fangs, 2 body parts, eight legs, eight or six eyes, and an innate ability to terrify the majority of humans.
-All spiders have venom and are poisonous, but it's mostly only poisonous to bugs.
-Male spiders have pedipalps, which are a combination of mating organ and arms, and they use them to do stuff, which is truly multi-tasking. And truly gross if you extend that concept to humans.
-Spiders' legs are attached to the head.
-Spiders are arachnids, and so are scorpions, mites, and daddy long legs (shiver)*. Daddy long legs have a single body part and don't produce silk.

Other interesting facts include that in the US, spiders are lone wolves and live by themselves because (see above) spiders will eat other spiders. Tarantulas are not true spiders because their fangs come down, not from the side. You might get bit by a tarantula, but you won't get hurt. Minnesota's poisonous spiders are the Northern Black Widow and the Brown Recluse. (Which didn't live here before, but thank you, climate change!) The Brown Recluse is gray or brown, has no markings on body, but a marking on the head that looks like a violin (or a fiddle, if the spider has attitude). If you are bitten by a brown recluse, the wound will take at least three months to heal. Put an ice pack on it to keep the venom from spreading, and go to the hospital.

At this point in the talk, I realized that I was spending too much time trying to figure out what kind of spider Shelob is. She makes silk and seems to make sheet webs (flat, convex or concave, only edges are sticky) or irregular cobwebs (no pattern, not sticky, spider sits in the middle), but her silk is definitely sticky, and not all of the 7 types of silk are. (There are four kinds of webs. Funnel webs are like a sheet web but with a hole in the middle, and orb webs are the classic spider webs, the webs that make all other spiders jealous. They have vertical spokes, which are not sticky, and spirals, which are. It takes a spider about 20 minutes to make one, and they rebuild them every day or so.) But spiders that live on webs are almost blind, and Shelob certainly can see. And talk.

I would not be at all surprised if she eats her silk and reuses it, as spiders do. She's an active hunter and jumping spider, but those species do not build webs, only the occasional trip wire to warn them when prey is near. They see well and do a mating dance, which I really can't see Shelob enjoying. For web-building spiders, the male plucks the lady spider's web so she will know he's not food. Active hunters have different silk glands, and they make cottony little, white swabs for their babies.

Speaking of babies, they can't stay in the nest long after they are hatched because their siblings will eat them, so they practice "ballooning," casting one line of silk to get themselves to safety. You've walked through them on your travels in the woods.

Non-mythical spiders live 2-3 years and can have three thousand spiderlings, 2-3 hundred in a single egg sac. Which is something to think about just before you fall asleep.

After the presentation, we went outside to find spiders around and on the visitor center. No Shelob, but as I think she's tarantula-adjacent, she's not a "true spider" anyway.

Don't tell her I said that.

*I have loathed daddy long legs since I was a small child. They used to march through our house at one point every year, and I remember not wanting to walk down the hall to my room because one was hanging out on the wall, in my way.

Fort Snelling State Park: The Beach

We are going to chew the nougaty center out of this urban gem this week; yesterday we dipped our toe into the visitor center and Pike Island. Today, the beach. So far he's mostly playing with his new water pump shooter, which works. He's having fun.

People from states with oceans or even giant freshwater lakes will of course scoff at the following assertion, but they can suck it: this beach rocks. It's wide, sandy, and conveniently located near an international airport. I smell LAYOVER!

No one is going to be surfing on Snelling Lake, but you might be nibbled by fish. Nibbled on, not eaten by, which is something to tell the teenaged girls who were purposefully freaking themselves out with the GIANT FISH in the deeper part of the swimming area. "EEK! A six-inch perch swam by my leg!" Granted, if a 26-inch carp did that, I might EEK as well. And then I would move to the shallow area and let the sunfish stare at my ankles.

It was a transparently gorgeous day with no ulterior motives. We stopped at the Dollar Store on our way there to see about a new beach shovel. Finn has 27 of these, but I could find none this morning. These will last a day or two, but I tell myself the joy they will buy will be worth the dollars. (Parents lie to themselves all the time.) I also bought him a balloon, but that took a trip when I opened his door to fasten his seat belt. I got a face full of shiny, yellow smiley face and off it went, smiling and sailing over the roof of an unfortunate strip mall.

The water is warm and relatively shallow. Finn is 3'6" tall, and he would have to walk out pretty far to get himself into trouble. Still, there are no lifeguards here, so people should be vigilant lest their small child in a colorful innertube scares away all the geese or your 5-year-old buries his new yellow beach strainer in the sand and can't find it (I have no idea who that last example is).

There are two depth levels: sunfish and carp. They are separated by little floaties and the shrieks of adolescence.

Surrounding the beach is a large picnic area with many tables and grills. Trees dot the mown lawn providing some shade most everywhere, ensuring that fistfights don't break out over the prime spot to leave your trash behind when you go home.

There are changing rooms and bathrooms as well as a playground adjacent to the beach.

You can rent a canoe, and there is also a fishing pier, where they do regular "learn how to fish" events.

We went to the beach twice in one day and slipped a doctor's appointment complete with blood test (different blog) in between visits. Finn really enjoyed the sand and shallow, warm water, and the weather was perfection (low 70's, breeze, sunny blue sky). Due, I think, to the breeze, the mosquitoes were not noticeable, but there were some lovely biting flies, so I again recommend bug spray.
