There are over 1 million identified species of insects and spiders in the world with many more still awaiting discovery. Spider's don't have feelers (antennae) and insects do. Bees, Ants, Wasps, & Similar The human race maintains a peculiar love-hate relationship with this particular, if utterly useful, insect group. They also have a variation when it comes to senses. Spiders and insects also have a difference when it comes to their major body parts. More detailed information on a greater number of spiders is available in Jennifer Dewey's Spiders Near and Far (Dutton, 1993). Orb Weaver Spider . Relation between sulfur mass and body dry-mass, S µg = 7.2 (body mg), in spiders and insects combined was not allometric. You have seen many of the members such as spiders, centipedes, millipedes, flies, beetles, and crabs. There are many difference between spiders and insects; for example, insects have six legs while spiders have eight, insects eat various foods while spiders primarily eat insects, insects have antennae while spiders do not and insects often have wings and spiders never have wings. Laurence Mound's Insect (Knopf, 1990) offers similar information; however, Johnson's book is more tightly organized and it covers a number of species not included elsewhere. It’s not surprising that people often ask ‘Is a spider an insect?’; both types of animal are small, have thin, jointed legs, and tend to dart about somewhat unpredictably. C. G. Giebel described these spiders for the first time in 1869. Bees, Ants and Wasps are well-represented in their Hymenoptera order as some 18,000 species are recognized in North America alone with … Spiders have 8 legs whilst insects have just 6 legs. Their genus name is a blend of Agelena and opsis, with the former being referred to the Eurasian grass spiders and the latter a Greek word, meaning to have a similar look.
Next, insects have bodies, which are in three parts, while spiders only have two. The similarities between arachnids such as spiders and insects are due to their shared ancestry… Spiders are more closely-related to other arachnids, such as scorpions and solifuges (camel spiders), than they are to insects.

SUMMARY: 1.Spiders and insects have differences in their major body parts. Spiders and insects are still together in this group, as are crustaceans, centipedes, and the famous extinct Trilobite.Arthropods are an incredibly successful group of animals and can thrive in the deep ocean, wet forests, and extremely hot deserts. They lack an insect-like antennae and have one more set of legs than insects, which generally feature six limbs [source: Explorit Science Center]. The main difference between spiders and insects is that the body of spiders is divided into two segments: cephalothorax and abdomen, whereas the body of insects is divided into three segments: head, thorax, and abdomen. Getting more specific, we move into the Phylum of Arthropoda.
