Heat, Humidity, and Harry Potter

After a brief retreat, during which I completed the seventh installment of Harry Potter, I’m returning to the world of field work, flogging and fun. [The book, by the way, was excellent, and I’m excited and willing to discuss it with anyone who has also read it, or who wishes the ending to be spoiled. Also, I want to give props to my younger sister, who predicted the ending with remarkable accuracy.]

This week we’ve been battling some classic Minnesota summer weather. The whole week has been extremely hot, and exceptionally muggy. To the consternation of some and relief of others, we switched our working hours to be an hour earlier so as to avoid some of the afternoon heat. Driving into work one day, we heard the MPR weathercaster announce that there were going to be “sauna-like conditions” and recommended that people stay inside and avoid strenuous activity. The hardy members of Team Echinacea persevered undaunted however, and we made good progress in the monitoring of the Common Garden and at Jennifer’s plots at Hegg Lake. We welcomed back team members Rachel and Amy Mueller, and also received a visit from Ruth Shaw, who was valuable addition during this hot week, and who also came to Kensington bearing delicious lemon poppy seed cake.

Massive picture update

Now that I’ve gotten a new toy, I’ve gotten several more pictures. Not all of them are with this fun lens though.

Let’s start with the sex. Tittilating thorn hoppers! Mating monarchs! Lusty Lepidopterans!

Then there are the critters I don’t recognize. This looks to me like some beetle larva (but I really have no idea). Shiny beetle on some thistle.

Jameson has just informed me that these are thorn hopper larva. Around the Andes Tower property, we came across a spider having a meal of a dragonfly. Don’t forget tiger beetles.

As for our plant portaits, I’ve got some Asclepias speciosa, showy milkweed. Allium has some pretty neat flowers. Like Earl Grey tea? Then you’ve had some of the tasty wild bergamot, Monarda fistulosa. The common garden has quite a bit of Solidago rigida, or stiff goldenrod.

So You’re Telling Me They’re Not Bees?

Do You Know What Kind of Insect This Is?

Team Echinacea sure didn’t until some crafty web searching informed us that these mysterious holed creatures are the larvae of Tiger Beetles. A frustrating day a few weeks ago was spent trying to figure out what lived in these 1 centimeter in diameter holes. Careful observation seemed to disprove what we had always assumed before; that they belong to the solitary bees that pollinate the Common Garden. You know what they say about when you assume…

What you can see is the underside of its head, as is visible in the diagram below.

The larva at the top is sitting and waiting for something edible to walk by before it attacks. Apparently the bottom one confused the nearby rock with actual prey. This footage was acquired in the common garden with the assistance of excess equipment from Team Video.

Had that rock actually been an ant the larva would pull it to the bottom of its hole (which can be up to 1 meter long) and devour it. Later it will fling the indigestible exoskeleton out. Additional footage captured the larvae flinging dirt out while expanding its home. Simply more information about the inhabitants of the Common Garden.

Orchid Hunting

On July 9th Team Echinacea temporarily became Team Platanthera. That is to say, we journeyed c. 170 miles northwest of our usual study area, around Kensington, to the Nature Conservancy’s Pembina Trail Preserve near Fertile, MN. Here we searched for Platanthera praeclara, the elusive Western Prairie Fringed Orchid. The WPF orchid is a midwestern prairie wildflower that has been listed as federally threatened since 1989. For more information about the WPF, where it persists, and why it is threatened, check out this link .

Gretel has been surveying the population at Pembria for the past several years to track changes over time and to better understand the effect of management techniques such as burning and mowing. Though prone to wide population fluctuations, this year we found an exceptionally low number of orchids – 151 between the two plots (108 and 43).

As usual, the day did not close without Team Echinacea/Platanthera hijinks. While wading in a drainage ditch, Jameson picked up a leech between his toes which Ian subsequently, and stalwartly, removed. We also stopped for pizza on the way home. Not to toot my own horn, but my recommendation (jalapeño and pineapple), though widely scoffed at initially, went over quite well with those who partook.

Finally, I leave you with these few pearls:
When the emotions are strong one should paint bamboo; in a light mood one should paint the orchid. – Chueh Yin

Inspired teachers … cannot be ordered by the gross from the factory. They must be discovered one by one, and brought home from the woods and swamps like orchids. They must be placed in a conservatory, not in a carpenter shop; and they must be honored and trusted. – John Jay Chapman

“When two friends understand each other totally, the words are soft and strong like an orchid’s perfume��? – anon

“A human being isn’t an orchid, he must draw something from the soil he grows in��? – Sara Jeannette Duncan

Andy and the monster plant

We had a long afternoon of monitoring today. Andy and I worked together. On Andy’s turn to measure we got row 35, which just happens to contain the monster plant. This plant has by far the most flowering heads in the garden. This year it has 15 fully developed heads and 2 pipsDSCF002600.JPG

It took about 40 minutes to record all the data on the plant.

The top head in this picture is a dud and the lower head is a pip.

Jennifer told me to take a picture of this inflorescence; so i did

Some more monitoring stuff

Here is a picture of a pupa case on an Echinacea; albeit out of focus

We have been calling these ant nests

Wu-tang cloud

The cameras were over-heating filming under the hot sun all day: so Andy bought hats for all of them to wear.

These pictures are from the afternoon of July 5th. We were taking pictures for fluctuating asymmetry to be analyzed later to see how ray floret shape affects pollination. that afternoon we saw a cloud that bore a strange resemblance to the wu-tang clan symbol

These are thorn hopper larvae. we have been calling them thorn hoppers. In the past they have been called black spikeys.

Here are my daily photos
DSCF1182.JPG
this first one is actually from yesterday

KAP took the kite w/ camera up over the common garden today so they could fine tune the procedure and technique for getting good aerial photos. I took these photos as I was helping put staples in the garden and change camera batteries

The little black speck half-way up the kite string is the camera
DSCF1195.JPG DSCF1196.JPG DSCF1194.JPG Stuart was holding down the kite.
the common garden is kind of half garden half prairie.

these pictures are from monitoring/measuring/demography/demo of the common garden. Basically it means finding each and every plant in the common garden and measuring and recording every aspect of them

Friday the 13th

Kite Aerial Photography is not going well. Friday the 13th was a particularly bad day.

MORNING: In the morning Josh, Julie & I drove to NNWLF. We set out ground markers and got the kite up. After we got the camera up we realized that the remote control wasn’t going to gain us much with the canon S70 because it take about 10 seconds between shots in the RAW mode. The interval on the timer is about 15 seconds. Then the camera battery ran out ARG. So, we went back to lunch.

AFTERNOON: Armed with fresh batteries we went back to NWLF and set out the ground markers, got the camera up, and took a lot of shots. Or so we thought. When we returned I found that there were no photos on the card. We’re not sure what happened. Perhaps the LED didn’t trigger the sensor. The problem was we didn’t check. ARG.

EVENING: Julie & Josh painted the kite line at 10 meter interval, so we could gauge the height of the camera. When the paint dried, I went out the roll up the string and found it was in four pieces. Some animal had chew through the line in several places. ARG.

Well, we are learning a lot. We have a long way to go before we are a well-oiled KAP machine.

Of course there was a fine finish to the day. I was working on the computer and got distracted for a few minutes. Then I heard thunder in the distance and the power went off for a few seconds. I lost the first version of this lament. I then pulled the plug on all computers and went to bed.
