Pacific chorus frog tadpole / Sierran tree frog tadpole
Pseudacris sierra

A friend gave me a bowl of frog eggs attached to some kind of oxygenating plant (Myriophyllum sp., aka milfoil?), duckweed, and a couple of small snails from her barrel pond on 05/21/11. Within a week 2 tadpoles hatched. They were very tiny and extremely good at hiding. I was worried the others wouldn't hatch, but when I shook the bowl, they wiggled inside their egg cluster.

The day after I took the photos above, I transferred the pond water to a 5 gallon aquarium where I had water sitting out a few days to allow the chlorine to dissipate. The agitation from the transfer released the remaining tadpoles from their sacs. There were other miniscule organisms swimming around in the water that I could only see in the sunlight. The aquarium turned green with algae fairly quickly. I siphoned off some of the water and refilled with fresh water. Turns out this may not have been necessary, because as the tadpoles get larger and the duckweed spread to cover almost the entire surface, the water has become clearer on its own.

It's been fun watching the tadpoles grow. By 06/10/11, they already started looking "pregnant" with big round bellies and could no longer cling to the side of the aquarium. Quite honestly, I'm not sure what I'm going to do with these frogs once they metamorphose. My friend collected tadpoles from a pond in Seaside last year and added them to her existing barrel pond here in Pacific Grove. By the first of April, she witnessed 3 sets of frogs mating. She made a video for the sound recording; click here to listen to how loud they are.

ps 07/11/11 - The oxygenating plant the eggs were attached to is rigid hornwort (Ceratophyllum demersum). While this greenery is good for aquaria and is found worldwide, it is not necessarily beneficial out in the wild.

posted 06/19/11 - Sometime around the second week of May, I first noticed my friendly scrub-jay's 3 youngsters. They were pretty awkward flying and mainly watched mom from the branches of this Douglas-fir I'm featuring in the the Tree Year Project. After getting a peanut, she would always fly back to their low nest in a nearby oak tree, I think to encourage the little ones to follow her for food. Then a late night ruckus happened, which sounded too much like a raccoon/scrub-jay fight, and I only saw the one pictured above for almost 2 weeks. Since then, two of the juveniles have been loudly following mom's every move. She chases them away from our balcony and will quickly sound an alarm call if a hawk is in the area. In the past few days they seem to get up before she does, and one quickly snatched a couple peanuts from me yesterday morning. Each one is a little different in voice and boldness of behavior, like stealing mom's stashed peanut from a pine cone. It's been a real joy to observe the mother scrub-jay teaching her young.

posted 06/18/11 - I mainly want to show the color variation of these caterpillars that I'm attempting to raise - from bright white to tan side hairs. These three were munching away at young shoots of Douglas-fir. I collected a third caterpillar from the Highlands the day I took this picture on 05/28/11. Add in the two I found around home, I've had 5 total. They seem to prefer hanging out together; in fact, they'll follow each other along a plate's edge like a caterpillar conga line whenever I switch out food. Except for the Highlands Easter caterpillar, I don't know which individuals came from where.

One successfully pupated and has been tucked in its cocoon since 05/01/11, one died 05/21/11 from what appeared to be parasites, and another one died 06/10/11 from what looked to me like typical Btk poisoning - the body was deflated and limp, like a plant that hasn't been watered, with only the middle sets of prolegs keeping the body attached to the nylon top.

I moved the two remaining caterpillars to a clean container. They now occasionally feed on Monterey pine (Pinus radiata) even though I'm still providing a mix of clippings. They rest most of the time upside down from a new nylon top. Their poop has gotten inexplicably smaller. I'm starting to get concerned because they don't seem to be progressing in their development. I suspect they may need a snack of another plant in order to successfully pupate - this is totally wild speculation after reading about Queen butterflies needing to snack on non-host plants in order for their adult pheromones to be chemically complete. I'm starting to remember all too clearly why I once gave up rearing caterpillars. Click to read a past post about how and why I'm raising these caterpillars.

ps 06/25/11 - As I was changing out the tree clippings, one of the caterpillars had started making a cocoon with hairs from its body and silk. I hope I didn't disturb it too much.

honey bee ~ 05/21/11 ~ J's place

Cordovan Italian honey bee
Apis mellifera ligustica

Pictured above is a top-bar hive a friend recently set-up in her garden. It's different than the typical box hives with frames as it allows the bees to make their own hanging wax comb. What I really liked was the observation window to see inside the hive - so totally cool! She ordered light-colored Cordovan queen and package bees specially bred for their gentleness and hygienic behavior from C F Koehnen & Sons here in CA. She's hoping mites won't be a problem with this hive as she's chosen not to treat her bees with chemicals. Her previous queens were Minnesota hygienic Italians and she's had great success with them.

My friend is quickly becoming the queen of bees herself. She started beekeeping for the first time last year at the beginning of May. I've been most impressed with the amount of research she's done on selecting traits in queens and types of equipment. I posted pictures of her 2 original hives on 07/01/10 and now she has several hives in 3 locations. Check out her pictures and a very loud video of the 2 swarms she had last year. Just a few days after the photos above were taken, another one of her hives swarmed on 05/25/11.

ps 06/21/11 - One of my favorite blogs I follow is Curbstone Valley Farm. Clare has recently redesigned her blog and I love it. To see her series of honey bee posts, click here.
