Spiders on the Move




 

One of the earliest signs of Fall is the almost frantic actions of the spiders who seem in a rush to reproduce or prepare to hibernate. Spiders are a most interesting invertebrate in both appearance and habit. All are predators which make them valuable to the gardener as they will eat flies, mosquitoes, grasshoppers, locusts, cockroaches, and aphids. The habits differ among species with some making intricate webs to trap their prey while some lie in wait on flowers and some simply travel about on the ground.

 

Most spiders live one season, however some species live long lives and spend the winter in a semi-hibernation. The Fiddlebacks have hidden in the rafters, behind the books, under the bed, and in other out of the way places ready to begin winter hibernation. Over the Winter they will grow and shed last years 'shell' leaving behind the empty casing... the empty casing is a sign that a more mature one is lurking somewhere nearby. The gentle Tarantula has an extremely long life expectancy and will easily live up to 20 years in captivity. The record has been set by a female who resides in LA and although her age was unknown at the time of her capture, she is now fifty years old.


Spiders are found in every corner of the planet, making them one of the most common invertebrates and they alone have eight legs. True spiders (thin-waisted arachnids) evolved about 400 million years ago, and were among the first species to live on land. There are many references to the spider in popular culture, folklore and symbolism. The spider symbolizes patience for its hunting with web traps, and mischief and malice for its poison and the slow death they cause their prey. (Who could forget the pitiful death sequence in the movie ‘The Fly’?)

Though not all spiders spin gossamer webs, spiders have been attributed by numerous cultures with the origin of basket-weaving, knot work, weaving, spinning, and net making. Lovely pottery artifacts featuring spiders may be found in all ancient cultures, so respect for them is universal.





Any talk of spiders includes the two most dangerous in
North America and they must be addressed. All spiders have venom however the Black Widow and Brown Recluse (Fiddleback) are very dangerous species whose bite may have disastrous affects on humans. The Brown Recluse likes living in quiet corners of the house while the Black Widow universally resides outdoors. A member of the Tangleweb family, the Black Widow makes an untidy web as the name implies and will aggressively guard her egg sac. Tomato baskets are a favorite place for her nest... so collect carefully. Tangleweb spiders have thin legs and a fragile skeletal structure, making them easy to squish... do not hesitate to kill them. You will notice a trace of the deadly 'goo' afterwards. 

 

A favorite spider which comes to mind is the darling fuzzy black jumper.
One summer we had a black fuzzy with emerald green fangs who took up residence in the kitchen. Every morning as the household awoke and greeted her, she would lift her 'arm' and wave... a marvelous trick by any standard.



 

There is an entire psychological phobia named after fear of spiders called Arachnophobia. So popular is this fear that comic book creator Stan Lee embraced it, introducing an irresistible spider hero in 1962. Spiderman instantly became an all time favorite.
