Acacesia Benigna
''Acacesia'' is a genus of orb-weaver spiders first described by Eugène Simon in 1895. It contains six species with a mostly neotropical distribution, ranging from South America to Mexico. One species, ''A. hamata'', is found in the US as well. Description The backs of spiders in this genus are marked with a dagger shape, outlined in black and surrounded by a triangular folium.

Dagger
A dagger is a fighting knife with a very sharp point and usually two sharp edges, typically designed or capable of being used as a thrusting or stabbing weapon.State v. Martin, 633 S.W.2d 80 (Mo. 1982): This is the dictionary or popular-use definition of a dagger, which has been used to describe everything from an ice pick to a folding knife with pointed blade as a 'dagger'. The Missouri Supreme Court used the popular definition of 'dagger' found in Webster's New Universal Dictionary ("a short weapon with a sharp point used for stabbing") to rule that an ordinary pointed knife with four-to-five inch blade constitutes a 'dagger' under the Missouri criminal code.California Penal Code 12020(a)(24):"dagger" means a ''knife or other instrument'' with or without a handguard that is ''capable of ready use as a stabbing weapon'' that may inflict great bodily injury or death. The State of California and other jurisdictions have seized upon the popular-use definition of a dagger to clas ...

Spiders Of Mexico
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Araneomorphae Genera
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...

Cyclosa
''Cyclosa'', also called trashline orbweavers, is a genus of orb-weaver spiders first described by Anton Menge in 1866. Widely distributed worldwide, spiders of the genus ''Cyclosa'' build relatively small orb webs with a web decoration. The web decoration in ''Cyclosa'' spiders is often linear and includes prey remains and other debris, which probably serve to camouflage the spider. The name "Cyclosa" comes from Greek 'to move in a circle', referring to how it spins its web. While most orb-web spiders face downwards in their web when waiting for prey, some ''Cyclosa'' species (e.g. ''C. ginnaga'' and ''C. argenteoalba'') face upwards. Notable members ''Cyclosa argenteoalba'' '' Cyclosa argenteoalba'' builds two types of web, a traditional sticky spider web, and a resting web that consists of just a few strands. When infected with a larva of the wasp '' Reclinervellus nielseni'', the spider switches on the behavior to build a resting web. The larva then eats the spider and uses ...
