"SPIDERS & THEIR PREY".
Am unable to ID the spiders in this series. One of them is as TINY as a pinhead. Have done my best to amplify the images in question. You may ENLARGE them by clicking on the RIGHT BOTTOM CORNERS of the "imports".
There are numerous species of spiders present in the Calgary area. Most of the spiders are harmless and help in controlling other insects. The four most common spiders found around here are: the House spider, Jumping spider, Cellar spider, and Yellow Sac Spider. None of which are considered dangerous to man. The two spiders which are to be considered dangerous, Black Widow and Brown Recluse.
The House Spider - The spider most commonly encountered in the home. Oddly enough the average home is too dry to support this species. Couple the dryness with the small size of new born spiderlings, the mortality rate is about 98%. The house spider selects web sites at random and abandons them if the food supply in the area is not plentiful. The area most common is the ceiling / wall junctures of rooms. Areas that have a high moisture content such as damp crawl spaces etc are likely to be full of these webs. The webs contain the egg sacks of the house spider. Each sack may contain up to 250 eggs. When conditions are favorable two or more egg sacks may be found in the same web. This spider has a body length between 1/4" to 3/8".
The Jumping Spider - This is a hunting spider and is found sitting on walls inside homes. This species of spider is capable of jumping from a few inches up to 6 inches in one leap. They feed on flies and other insects. This species has colorful markings on the surface of the abdomen. Most of these spiders are transported into the home on firewood.
The Cellar Spider - These spiders are quite common in cellars, barns and damp warehouses. Their legs are quite long. Two species are commonly encountered, the long bodied cellar spider, and the short bodied cellar spider. The former has a body length of 1/3 inch, and legs up to 2 inches long. The latter a body length of 1/10 inch and legs about 1/3 inch long.
The Yellow Sac Spider - These spiders build their silk retreats in upper corners and the joints between the wall and ceiling. Females produce several egg masses, each containing 30 to 48 eggs. This spider is pale yellow or pale green. Females have a body length of 3/16" to 3/8", males 1/8" to 5/16" . Entrance to the home is through faulty screens,cracks around doors and windows, gaps around pipes or any other suitable entry point. Once inside it prefers to stay where food is readily available. This spider more than any other species, is responsible for spider bites throughout the United States and Canada. Bites occur when the spider crawls into clothing and is pressed close to the skin. The bite is generally harmless with a slight swelling, localized redness, and a burning sensation at the site.
Please read about the Recluse Spider in this piece.
The Daddy long legs is MOST INTERESTING.
Here they are: Daddy long legs. The EYES are truely beautiful. The UNDERBELLY of the spider. She is EYEYING HER TRAPPED PREY. The tinniest spider I've ever seen. I first thought it to be a small fly. But, then I VERIFIED IT TO BE A TINY LITTLE spider. Here now is the female that had devoured it's Mate. The HOUSE SPIDER was photographed in Vancouver Island. Now, the MOTH I cannot ID it either.
The Collage may also be ENLARGED similarly. |

Hello Mario. Excellent collection of spiders and prey in beautiful display frame. Good sharp focus and all are excellently exposed for clarity. Clever image manipulation and very well done. Best regards. Jusni
Namastay Mario,
A nice collage of all these spider and the unknown moth. Very well composed and good details in every frame. Yes One of them is Daddy long legs and I think the moth is some type of underwing moth, The tiny spider I think is a cross spider. Thanks a lot for sharing.
Sincerely
Haraprasan
Fine collection and lesson Mario. For some reason my son tells me that the daddy long legs isn't a real spider...he brought that up randomly 2 days ago..I put it in the back of my mind but see you ref it today so I did some research. Your images very many times lead me to do research which is what makes your total presentations such a good learning tool.
