phyllocnistis citrella

The citrus leafminer is a very small, light coloured moth that arrived in California from Mexico in 2000 and has now spread throughout most of California. I’ve never seen an adult, but the larval action is very evident in my yard, especially on the young lime trees. They only infest fresh growth, which of course is just about all a little tree has!

I’ve been removing the affected leaves, but today I read that it’s not a good idea, because it just creates even more fresh growth for the larvae to mine. Apparently the insects will die off over the cooler months; here’s hoping, too, that natural predators come along to help create balance.

sharing the love

Twenty 7-12 year olds (and their parents) now know the difference between a valley oak and a coast live oak, though hopefully that’s not the only thing they gained from our time together 🌿💚

lemon tree very pretty

I sketched a kookaburra in the guest book at our lodgings, but forgot to photograph it before we checked out this morning. But here’s a lemon tree instead.

We’re done with north and central Queensland; our last few days in Australia will be spent in southern Queensland.

tropical beauties

I think this Golden Orb Weaver is Trichonephila plumipes, sometimes called a Tiger Spider. Its web glows yellow, and the legs are a light orange colour, black at the joints. Big spiders are so impressive! This type is not confined to the tropics, so I hope to see more when travel to the sub-tropics.

There are some 750 different types of pandanus; I have no idea which one I was sketching! I love their aerial prop roots.

platanus racemosa

I took myself down to a nearby (dry) creek and sat in the shade of a California sycamore for a while. This is my favourite local native tree, with its mottled leopard bark and floppy clown-glove leaves. I’d plant one at our place if we had the water, but alas our block is too dry for a sycamore to thrive here.

psidium cattleyanum

Our strawberry guava tree is busting out all over with fruit in varying stages of ripeness. We usually leave them for the birds to eat, though sometimes I’ll gather enough to extract a cup or two of juice. We preferred the lemon guava, but sadly that tree died after a few spectacular crops.

When looking up its Latin name, I learned that Psidium cattleyanum is (a) named for English horticulturist William Cattley (1788 – 1835) and (b) considered the most invasive plant in Hawaii. So many unintended consequences, when we move biota around the world.
