SEASON 4 MONARCH BUTTERFLIES
Tuesday, March 19, 2024
From a lifetime in Yosemite Valley
"A long dark tunnel, with a far away bright light, which after a moment appears to grow larger... and larger until you burst through into a bright and beautiful place that other's say: "Looks like heaven."

"Doc" Ricketts, John Steinbeck, Monterey and the Sea of Cortez
"The tide teaches us to live with mystery and complexity. It lives in the body of a mud shrimp, signaling when to swim and when to burrow. It lives in sandpipers, crabs, and whelks. It lives in the spirit of bores, in the prayers of monks. The tide is vibration, music, time." —Jonathan White, Tides: The Science and Spirit of the Ocean
Waiting for Doc to answer the door, I knock again, but the timing is off (about 80 years.) He's not here, but I more clearly imagine Ed Ricketts and John Steinbeck just inside.
Teaching biology has so many wonderful parts like when students are able to connect the dots, especially when two seemingly different worlds collide. The worlds of literature and biology.
My favorite biologist, Ed Ricketts, and my favorite novelist, John Steinbeck, spent some of the richest moments of their lives, here just inside this door at 800 Cannery Row in Monterey California. Here is where they planned their expedition to the Sea of Cortez.Image credit: Jeffrey M. Banister, Journal of the Southwest, Vol. 62, Number 2, Summer 2020

Monarch Butterflies and Tropical Milkweed Do's and Do Nots.
OE damage takes place during the chrysalid stage. While the infected adults do not survive to migrate, they do spread the protozoan parasite. If you see the sign of infection above, keep this butterfly isolated when it emerges.

NAMING RIGHTS TO SAGAMARTHA (aka Everest), THE HIGHEST MOUNTAIN IN THE WORLD
Everest never saw the mountain and never visited the area, but the mountain was given a colonial name without the consent of the Nepali people.
Nor was Edmund Hilary the first to climb Sagarmatha.
wiki In November 2020, Nepali politicians claimed China had annexed more than 150 hectares of Nepal land. The Nepali government in September 2021 formed a team
This team submitted its report on 26 September which brought the conclusion of claim being truth. It suggested making a joint force for dispute resolution. In early 2022, a Nepali government report was leaked. The report indicated the previously alleged buildings were on Chinese side, but found that China has built fences, a canal, and a road that encroached on Nepali soil.[20]
Sagarmatha (Everest) borders China and Nepal. From it's highest point, the southern slope in Nepalese, the northern Chinese. This view from the south shows the Nepalese view of Sagarmatha.

SEASON 3: MONARCH BUTTERFLY
Tuesday, August 29 of the vivarium six, 1 caterpillar (A) fatality (tachinid) today. The four remaining larvae are simultaneously briefly and unexpectedly pausing their feeding behavior (all are still). (B) missing one antennae is now 10:39 am) on the netted vivarium "ceiling". Is it ready for it's chrysalid stage? No. It has descended back to the wooden deck. 10:45 am now back to the ceiling. 10:50 now at leaf level. 10:53 now at bottom.
Monday, August 28, 2023 Monarch caterpillar census 10 (five on the deck, six in the vivarium). The 6th, too small to be noticed, maybe 1st or 2nd install, was a milkweed stowaway. Idea: this larva too young to be parasitized? Only 5 seeds sprouted from the 40 tropical milkweed seeds from 2021. From a late start*, caterpillar activity is back in full swing.
*Later start because of wet winter, and/or cooler temperature?
Tuesday July 25, 2023 A. I found a monarch caterpillar today on the soil near the base of a tropical milkweed on the front deck (south long planter.) B. Also, planted (in a 4"X10"tray) 40 seeds originally collected between November and December 2021. C. Milkweed trimmed down to 3inches on the south side of the house have not yet come back. 4 containers of tropical milkweed (on or adjacent to the deck) are growing fast.

Sunday, July 23 Paul has 20 monarch caterpillars in Zone 3. They are eating milkweed faster than the plants can grow.
See photo -->
How many caterpillars are in this photo?
Friday, June 23, 2023 5th straight day of sunshine. Paul (Zone 3 on the map) reports that his first monarch caterpillar has just gone to chrysalis stage. Let's check where he is on the map. I bet it's warmer in Zone 3.
Tom and Virginia(Zone 2) report they've spotted monarch adults in the last few weeks, but none seen here is South Laguna. Only 1 butterfly sighting (laying eggs) here in Zone 1 but I only found 1 egg.
Wednesday June 21 Third sunny day in a row following 9 weeks without sunshine here in Laguna Beach, which may explain why we haven't seen monarch butterflies as of this date.
Milkweed has sprouted from last seasons trimmed 3 inch stalks. (See Figure 1 below). So there is plenty of food when they arrive.
Almost Season 3.
Wednesday, Feb. 1, 2023 I have trimmed last season's tropical milkweed down to about 3 inches from the ground. This will reduce Monarch butterfly exposure to the fatal disease known as OE Ophryocystis elektroscirria (See Figure 2 below) Click HERE for more.
Spring temperatures are a few weeks away but good news has been published.(See Winter Count below)
WINTER COUNT SHOWS REBOUND FROM NEAR EXTINCTION
2020 Fewer than 2000 butterflies
2021 247,000.
2022 330,000
OE damage takes place during the chrysalid stage. While the infected adults do not survive to migrate, they do spread the protozoan parasite. If you see the sign of infection above, keep this butterfly isolated when it emerges, Place milkweed florets with blossoms to feed the isolated adult.
To control the dangerous spread of Ophryocystis elektroscirrha (OE), a parasite that infects monarch butterflies, I have cut my tropical milkweed plants down to 4 inch stems without leaves. (see photo below)
