Seed of the Week: Tamarack Larch

Our mystery cones from last week are from the tamarack larch or American larch, Larix laricina.

I was hoping someone would notice that the tree was lacking pine needles or leaves, although it had cones.

Here is the same tree in the summer. I love the soft, lacy foliage.

Larch trees are unusual conifers, because they are deciduous. The trees lose their needles/leaves in the winter.

Tamarack larch trees grow throughout the Northeast. They are very cold tolerant. Related species grow in northern Canada, Russia and northern Europe.

Look at the fall color of this stand of tamarack larch (by Linda Baird-White at Wikimedia)!

Have you ever seen a tamarack larch? Where was it growing?

Bug of the Week: A New Milkweed Bug

You never know when you are going to find a new insect here in Arizona.

Glancing quickly, I thought the read and black bug below feeding on a desert milkweed flower was a large milkweed bug, Oncopeltus fasciatus.

But looking again, I realized it had two black bars across the center of the body, rather than one wide one.

This is an adult Oncopeltus cayensis. I don’t think it has a common name. Check out the sucking mouthparts it is using to feed on the flower.

Have you ever found something new when you took a second look?
