An impressively large species of salamander, possibly in the genus Bolitoglossa, found in the Chiriqui Highlands of Panama.
Prior to reaching the highlands we had been exploring the lowland rain forests and cloud forests of central Panama and I was overwhelmed with all the new and exciting amphibians I was encountering. However and not surprisingly, that diversity and density dropped off sharply as we reached the higher elevations of Cerro Punta and Volcan Baru (6500ft+) in the Chiriqui Highlands.
I did hear a single species of tree frog calling around our lodging at night but the calls were so sporadic and high in the canopy I could never locate the species. I didn't expect to find any salamanders on this trip so while out searching for frogs I was shocked to see a very large black salamander crawling up the side of a small hillock. Further searching revealed two more of the same species moving slowly along in the cool (50F) drizzly weather. The largest of them was found clinging onto a barbwire fence and was a good 5+ inches in length. This species ended up being the only amphibian we found in the Chiriqui Highlands.

If anyone can help me ID this animal down to the species I'd really appreciate it!
The orb web of this baby signature spider or 4 legged spider is glowing in the soft evening sun rays.
These spiders make certain zig-zag pattern on web therefore also known as writer spider or signature spider.
Ran back to my room to grab my camera when I came across this one. I've been trying to capture a spider web since a long time.
Best viewed in full size.
I went outside early one morning to get the newspaper and found this spider web in front of our house.
A restoration of a damaged clip, but showing an interesting perspective on the back (presumably web making) end of the Tholian ship model from The Tholian Web. The ship sits on a stand in the studio. Another shot of the ship, from the side, can be seen here:

where the web making nozzle (if that is what it was intended to be) is just barely visible in side profile.
This relatively simple model was repurposed later in the third season as the Aurora in the episode " The Way to Eden " and can be seen as that ship here:

I'm not kidding, there are webs everywhere...I almost think I need to wear armor to go out in the garden...to protect myself from those biting brats.
A cook at the Weber Grill restaurant in Schaumburg, Illinois loads charcoal into a chimney device in preparation for starting up another grill in anticipation of the dinner rush. The grill next to him was burning pretty hot.
During the process of making an orb web, the spider will use its own body for measurements.
Many webs span gaps between objects which the spider could not cross by crawling. This is done by first producing a fine adhesive thread to drift on a faint breeze across a gap. When it sticks to a surface at the far end, the spider feels the change in the vibration. The spider reels in and tightens the first strand, then carefully walks along it and strengthens it with a second thread. This process is repeated until the thread is strong enough to support the rest of the web.
After strengthening the first thread, the spider continues to make a Y-shaped netting. The first three radials of the web are now constructed. More radials are added, making sure that the distance between each radial and the next is small enough to cross. This means that the number of radials in a web directly depends on the size of the spider plus the size of the web. It is common for a web to be about 20 times the size of the spider building it.
After the radials are complete, the spider fortifies the center of the web with about five circular threads. It makes a spiral of non-sticky, widely spaced threads to enable it to move easily around its own web during construction, working from the inside, outward. Then, beginning from the outside and moving inward, the spider methodically replaces this spiral with a more closely spaced one made of adhesive threads. It uses the initial radiating lines as well as the non-sticky spirals as guide lines. The spaces between each spiral and the next are directly proportional to the distance from the tip of its back legs to its spinners. This is one way the spider uses its own body as a measuring/spacing device. While the sticky spirals are formed, the non-adhesive spirals are removed as there is no need for them any more.
After the spider has completed its web, it chews off the initial three center spiral threads then sits and waits. If the web is broken without any structural damage during the construction, the spider does not make any initial attempts to rectify the problem.
The spider, after spinning its web, then waits on or near the web for a prey animal to become trapped. The spider senses the impact and struggle of a prey animal by vibrations transmitted through the web. A spider positioned in the middle of the web makes for a highly visible prey for birds and other predators, even without web decorations; many day-hunting orb-web spinners reduce this risk by hiding at the edge of the web with one foot on a signal line from the hub or by appearing to be inedible or unappetizing.
Spiders do not usually adhere to their own webs, because they are able to spin both sticky and non-sticky types of silk, and are careful to travel across only non-sticky portions of the web. However, they are not immune to their own glue. Some of the strands of the web are sticky, and others are not. For example, if a spider has chosen to wait along the outer edges of its web, it may spin a non-sticky prey or signal line to the web hub to monitor web movement.
Hard to believe, but a baby spider, just out of it's egg sack, can create a masterpiece just like this.
Early this morning my husband came back from feedingthe neighbor's dog and said, "You should go out there and see the field south of their house. It's full of orb webs covered with dew."
So I did.

This is a wasp tied up in a spider's web. I think that the wasp was still alive here, but I'm not sure. Its mouth parts seemed to move now and then as if it was trying to chew its way out.
The spider was a house spider - quite a lot bigger than the wasp. I had no idea that house spiders fed on wasps, but they obviously do.
I didn't see these wasps (there were two in the web) land in the web. I had been watching the spider for a while and then went away for 20 minutes or so. When I came back there were the wasps all cocooned like this. I wonder if the spider had stored them somewhere and then brought them back to the web where it could handle them and feed on them.
It makes a change for me to feel sadness and sympathy for wasps. A few years ago I watched wasps attacking and then decapitating bees. I felt sorry for the bees then, and no sympathy for wasps. But wasps meet harsh ends too. All part of nature's cycle.
