Chrysalis: Day 2

These photos clearly show the silk button that suspends the final instart prior to and after the fifth shed; the cremaster or hornlike stalk attached to the button; the green pupa inside a clear chrysalis; and the gold "pearls," which give the chrysalis its name from the Greek word chrysos for gold. Our chrysalis should look basically the same for the first 1-8 days. Around day 9-11, the orange and black color of the wings should begin to be evident in the chrysalis. The color should deepen and grow more apparent as we progress through days 12-14, and the butterfly prepares to emerge.

Picnic with Meeting

Violin: Day 1

Allison taught Kallan the names for the parts of the violin and bow, the technique for tensioning the bow, proper position for the violin, bowing, plucking (pizzicato), and the first 4 notes of Twinkle, Twinkle Little Star (twinkle, twinkle or ABCD if you favor the alphabet song lyrics).

Evening Aloft

A grand tour of Emily and Isabelle's new home amid the foliage: a cozy cottage with spectacular view, comfy seating, tasty snacks, and a handy block & tackle for retrieving bounty from the surface dwellers.

The Moral: Shake Out Before the Shake Down

New spreaders, an electrical overhaul, and Asterias sets sail. It is a testimony to how little we have been out in a year, that we (Carl, the kids, and I) thoroughly enjoyed whispering down the Severn under the bimini on a warm, virtually windless August day. We were enjoying the quiet glide until shortly after these photos were shot. I decide to shake out the mizzen for full effect and perhaps another fraction of a knot of speed. The sail cover was 1/3rd off when I was stung 4 times in the face by a paper wasp. No big deal, I rushed below smeared on toothpaste and applied ice while searching the 1st Aid Kit for bite treatment. In a few minutes, I was back in the cockpit marveling that there was very little pain. I grabbed the helm, and Carl went aft to throw off the sail cover and evaluate raising the mizzen. He barely dropped the cover to the deck, before I called him back to the cockpit. My ears were ringing, and I felt dizzy and shaky. I went down below for the medical supplies and returned topside with my heart pounding, my breath short, and my vision severely blurred and closing in from the periphery. I didn't tell Carl, but I couldn't even see the antihistamine he placed in my hand. We cranked the engine and called my parents who were out kayaking, leaving a message to meet us at the dock. We weren't far due to the lack of wind. Carl cranked in the yankee and dropped the main (thank goodness for lazy jacks and roller furling). I concentrated on not passing out: taking deliberate yoga-style breaths; using an ice water on my forehead, neck, cheeks, and trickled down my back; and willed myself to stay conscious. My parents met us at the dock. I was still lightheaded and nauseous, but my vision was clear, my heart had calmed, and breathing was easier. After a few hours relaxing in the air conditioning with ice packs on the bites, I am no worse for the wear.

Success (Stage 1)

One of our eggs has produced a caterpillar. I suspect this happened several days ago. On Wednesday, we noticed holes on the egg leave that none of us remembered seeing before. We did not want to remove the milkweed from the habitat for fear of dislodging the newborn. Judging from the size of the egg, they must be teeny tiny when they hatch. It was impossible for our untrained eyes to focus through the mesh and dissern a wee one . We figured a few days to allow for growth would prove if the holes were the result of caterpillar gorging. Here is the evidence: we have a munching, crunching monarch to be feeding on our waning milkweed supply.

Farmers, Warriors, Builders: Hidden Life of Ants

Visitors get a look at life from an ant's point of view with large-format photographs of ants going about their daily business, a cast of an underground ant city, and a live ant colony. (National Museum of Natural History)
 
The live and photographic displays of the leaf cutter ants were our favorite. The live display clearly showed the fungal gardens the ants cultivate on leaf compost.

Hurray! The Girls Are Back!

Emily and Isabelle have returned from Europe (Germany and France). No amount of rain would have been sufficient to dampen Kallan and Reece's enthusiasm about this home coming.

Mystery Solved!

The evidence is in. We scoured the remaining milkweed plants for new candidates and discovered 2 additional blobs that resemble the first one identified by Monarch Marie. Magnified 400 times and finally in reasonable focus, one of the blobs revealed the ctenophore-like striations evident in the expert's photo and the video clip. The kids recognize the similar patterning because they are quite familiar with comb jellies. We frequently catch them off the dock. We are temporarily basking in this success, but anxious for the next phase. Our stems with the three host leaves are safely in a butterfly habitat awaiting emergence of the caterpillars. Keep your fingers crossed for us.

Butterfly Update

Ok, Kallan, Reece, and I found the photo (left) of a monarch egg on the internet. Unfortunately, ours look as follows: Round: the egg we received on Saturday from Monarch Marie; Oblong: the eggs we identified on the milkweed from PA. The resolution on our $35 Eyeclops Bionicam is clearly inferior to the photographic equipment used to capture the confirmed egg, but the differences among the three are still striking. We thought maybe ours had already hatched, and we were looking at remaining egg cases lacking a developing caterpillar. But, according to internet sources, the emerging caterpillar eats the egg case in the process of hatching (see the video clip below) for immediate sustenance. So we have a mystery, what are these egg-like things? Does anything else lay eggs on milkweed? We will do some more research and continue to wait and see. In the meantime, we will scour our milkweed for other monarch egg candidates.
