Beyond Webs – Swimming, Spitting and Other Spider Hunting Methods – Part 2

Deinopis subrufaPlease see Part 1 of this article for a look at the unique hunting techniques employed by Fishing, Trap Door and other spiders.

Orb Webs

I’ve been avoiding “traditional spiders”, but wanted to include an observation I made over 20 years ago in Costa Rica.  I was tossing katydids into the huge orb webs that were abundant near my research station.  The web-owners (Nephila spp.) wrapped the insects in silk and then administered a bite.  Then I offered lubber grasshoppers – the same size and shape as the katydids, but equipped with immensely powerful rear legs.  On several trials, the spiders first pulled off the grasshoppers’ rear legs, then wrapped and bit the insects.  I imagine they were attempting to limit damage to the web.

Beyond Webs – Swimming, Spitting and Other Spider Hunting Methods – Part 1

Trapdoor SpiderSilk webs are amazing innovations, and the “sit and wait” tarantula stategy is remarkably effective…but among the world’s spiders we also find a mind-boggling array of other hunting techniques.  Some of these odd hunters, such as Fishing, Jumping and Trapdoor Spiders, occasionally appear in the trade…all are worth a closer look.

Tarantulas (Mygalomorphs) and Their Relatives

Tarantulas are the best known of the Mygalomorphs (spiders distinguished by, among other things, fangs that strike downward as opposed to side-to-side).  Some relatives stray from the “sit and wait” strategy: Read More »

Insects, Spiders, Other Invertebrates Have Distinct Personalities – New Research

FirebugMost invertebrate keepers have noticed that individuals of the same species often behave quite differently under the same circumstances.  For example, one Giant Bird-Eating Spider might feed in broad daylight and be content to remain in the open, while another refuses to eat unless provided with a deep burrow and complete darkness – I can recall countless similar observations.  Does this mean that these “simple” creatures have personalities?  According to a recent study, the answer may be “yes”…

How Does One Test Insect Personalities?

An article published in the September, 2010 issue of The Proceedings of the Royal Society (B), reveals that individual insects exhibit distinct personality traits, and that these traits remain consistent in different situations. Read More »

Choosing the Ideal Substrate for Reptiles, Amphibians and Invertebrates – Part 1

Western Spade-foot Toad Bark, moss, sand, coconut husk, wood chips …selecting the proper substrate for one’s pets can be a difficult task these days (in contrast to years ago, when we were limited to newspapers, earth or gravel!).  Please check out our extensive line of Reptile and Amphibian Substrates to see examples of what is available.

Factors to Consider

A number of factors – some obvious, some not – must be taken into consideration when deciding upon a substrate.  Some of the most important are as follows: Read More »

Invertebrate Health – Mites in Scorpion, Millipede and Tarantula Terrariums

Goliath BirdeaterI’m often contacted by Arachnid and millipede owners who are concerned about the tiny white “specks” that they notice crawling about their terrariums and on their pets.  In almost all cases, the little beasts turn out to be relatively harmless Mites.  Mites are actually Arachnids, related to spiders and scorpions, and are unique in the incredible diversity they have attained – over 45,000 species have been described, with many more than that likely remaining to be “discovered”.  Read More »
