Leaf Miner

(I’m BACK!!! Finally. It turned out my blog site problem was my browser. I am of the over-60 club and didn’t grow up with computers. They still intimate me on certain things. Anyway, I am celebrating today!!!)


Leaf miner patterns on leaves always fascinate me — how could a “critter” that small even exists?

The larvae of leaf miners feed on the cells inside the leaf, leaving a “trail” as they go. Feeding in the leaf protects them from predators.

The leaf above is off a lilac bush that I found recently.

I photographed this cottonwood leaf in August.  If you look close, you can see where a tunnel started in the lower left side of the picture. Then you can follow it as the larva ate and grew. Leaf miners can be larvae of moths, sawfies and flies.

Looper Mimicry

This looper caterpillar mimics a dried twig. Look close to see a “tie wire” of silk anchoring its head.

It didn’t like all the attention from me, and changed its position to look like a bent twig. Notice the black spot marking on its back. It shows in both pictures. To me, the spot looks like it was damage done to the “twig.”

Loopers are in a large family of moths known as Geometridae. They can easily be identified by only having a pair of prolegs at each end of their body. Other caterpillars have 4 prolegs in the middle of their body. Loopers move by bringing their hindlegs up near the front of their body. They then  take their front legs forward, giving them the “looping” method of moving.
