I figured , based on clues, I might see a big fat caterpillar up in our Desert Willow.

1- clues, 💩 about .1” (2.5mm) on the patio under the tree

2- a big fattie, about 3” (75mm) long, if you zoom in it’s nomming on a leaf held by tiny feets.

Soon a chrysalis, then a beautiful Sphinx moth #inverts

Pellets of caterpillar frazz lying on concrete under a tree. The tree is a host for Rustic sphinx moths.

A large green horn worm is hanging upside down as it grips a small branch of a host plant while eating a thin blade-like leaf. The caterpillar is about 3 inches long and as big around as a finger.

For fun, today I will walk through how acarology works, and how I got this mite I found by the Welsh shores down to species. This also applies to many insects. When someone says "Can you tell me what species this is?" is often a hard question to answer.

Close up photo of a tiny mite walking across a wet, muddy brown surface on the shore. This was the underside of a rock near LLanelli. Its body is a smooth, glossy, orange brown oval, longer than it is wide, that shines in the light. Paler orange legs and mouthparts reach forward to the left.

Yes, this is a real butterfly, not AI. Sometimes truth is stranger than fiction. Can anyone find the original source? I could only find this at Instagram here www.instagram.com/reel/DcWiNY3..., but can't find out anything else about Letroncio lean.va.

Black and yellow garden spider, Argiope aurantia, making a stabilimentum in her web. Different Argiopes have different types of these. There are a lot of hypotheses for why they make them, but no consensus yet. Not my video.

Poked around the yard last night after dark and took some #arachtober portraits. This is Say's Armored Harvestman (Libitioides sayi) which by name and appearance would fit in just fine in the Advanced D&D Monster Manual I had as a kid.

Crab-like reddish-brown arachnid with long legs, white markings on body and leg joints, crawling across a green leaf.

An entomobryid springtail enjoying a drying flower head. Needed a break and took this outside of my office. Ended up giving a tour of the tiny things people ignore.
