Order: Araneae<\/span><\/p>\n All spiders have two body segments, eight legs, and lack antennae. They typically have six to eight eyes arranged in two rows and modified mouthparts called pedipalps, which are spherical and enlarged on male spiders. Collectively, they range in size and color, depending on family and species. For example, jumping spiders (family: Salticidae) are relatively small, measuring about 4-12 mm (1\/7-1\/2 inch) long, and have abundant body hairs, while wolf spiders (family: Lycosidae) are 1.3-5 cm (1\/2-2 inches) long. Generally, male spiders are smaller than female spiders. Both jumping spiders and wolf spiders are usually black, brown, or grey, though some species of jumping spider are very colorful. Other spiders commonly found in gardens and landscapes include orb weaving spiders (family: Araneidae), funnel-web spiders (family: Agelenidae), crab spiders (family: Thomisidae), woodlouse spiders (family: Dysderidae), and ground spiders (family: Gnaphosidae).<\/p>\n [\/et_pb_text][et_pb_blurb title=”Quick Facts” use_icon=”on” font_icon=”||fa||900″ icon_color=”#F15625″ image_icon_width=”36px” _builder_version=”4.22.2″ _module_preset=”default” header_level=”h1″ header_text_align=”center” background_color=”#FEBD3B” custom_padding=”6%|6%|6%|6%|true|true” global_colors_info=”{}”]<\/p>\n [\/et_pb_blurb][et_pb_blurb image=”https:\/\/agsci.colostate.edu\/divi-agbio\/wp-content\/uploads\/sites\/127\/2022\/03\/16.-wolf-spider-scaled-1.jpg” alt=”Wolf Spider” _builder_version=”4.22.2″ _module_preset=”default” body_line_height=”1.4em” image_icon_custom_margin=”||-22px||false|false” global_colors_info=”{}”]<\/p>\n Wolf spider.

There are many spiders \u2013 wolf spiders, crab spiders, jumping spiders \u2013 that do not build webs but instead move about and hunt their prey on soil or plants. These less conspicuous spiders can be important in controlling insect pests such as beetles, caterpillars, leafhoppers, and aphids.<\/p>\n Female spiders lay eggs in clusters and most species cover their eggs with a protective sheet of silk. Some spiders carry eggs on their back until they hatch. Immature spiders are called spiderlings and often disperse by climbing to the top of a nearby object and produce long silk filaments, which they use to ride wind currents to new locations. This dispersal mechanism is known as ballooning.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.22.2″ _module_preset=”default” background_color=”#FFFFFF” global_colors_info=”{}”][et_pb_row use_custom_gutter=”on” gutter_width=”1″ _builder_version=”4.16″ _module_preset=”default” width=”100%” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”squiggle-left” _builder_version=”4.24.1″ _module_preset=”default” header_font=”||||||||” header_text_align=”left” header_font_size=”22px” width=”75%” module_alignment=”left” custom_margin=”||||false|false” custom_padding=”||||false|false” global_module=”23371″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n \t\t [\/et_pb_text][et_pb_text _builder_version=”4.24.2″ _module_preset=”default” header_font_size=”36px” custom_padding=”|4%|||false|false” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n Spiders are recognized as important biological control agents for managing pests indoors and outdoors. Indoors, spiders can help reduce the numbers of undesirable insects such as flies, mosquitoes, and moths. In landscapes and outdoor gardens, spiders can be important predators of insect pests such as beetles, caterpillars, leafhoppers, and aphids. Research also suggests that spiders are very abundant in grain crops, and they may cause high mortality of certain pests such as the diamondback moth (Plutella xylostella<\/em>).<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.16″ _module_preset=”default” background_color=”#F1F1F1″ global_colors_info=”{}”][et_pb_row use_custom_gutter=”on” gutter_width=”1″ _builder_version=”4.16″ _module_preset=”default” width=”100%” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”squiggle-left” _builder_version=”4.24.1″ _module_preset=”default” header_font=”||||||||” header_text_align=”left” header_font_size=”22px” width=”75%” module_alignment=”left” custom_margin=”||||false|false” custom_padding=”||||false|false” global_module=”23371″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n \t\t [\/et_pb_text][et_pb_text _builder_version=”4.24.2″ _module_preset=”default” header_font_size=”36px” custom_padding=”|4%|||false|false” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n Killing spiders should be avoided if possible. When spiders are found in the home, they can be carefully removed and placed outdoors away from the building. Cultural or mechanical controls can be used against pests to conserve populations of these natural enemies. When insecticides are used, their selectivity and the timing of applications should be considered.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.22.2″ _module_preset=”default” background_color=”#FFFFFF” global_colors_info=”{}”][et_pb_row use_custom_gutter=”on” gutter_width=”1″ _builder_version=”4.16″ _module_preset=”default” width=”100%” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_blurb title=”Full Jumping Spider Fact Sheet” use_icon=”on” font_icon=”||fa||900″ icon_color=”#F15625″ image_icon_width=”36px” admin_label=”Blurb” _builder_version=”4.22.2″ _module_preset=”default” header_level=”h2″ header_text_align=”center” header_font_size=”36px” custom_padding=”4%||4%||true|false” global_colors_info=”{}”]<\/p>\n Download or view the Jumping Spider PDF fact sheet for your reference.<\/p>\n [\/et_pb_blurb][et_pb_button button_url=”https:\/\/webdoc.agsci.colostate.edu\/bspm\/Arachnida%20%28Arachnids%29\/Jumping%20Spiders-1.pdf” button_text=”Full Jumping Spider Fact Sheet PDF” button_alignment=”center” _builder_version=”4.22.2″ _module_preset=”default” custom_padding=”||||true|false” global_colors_info=”{}”][\/et_pb_button][et_pb_text admin_label=”squiggle-left” _builder_version=”4.24.1″ _module_preset=”default” header_font=”||||||||” header_text_align=”left” header_font_size=”22px” width=”75%” module_alignment=”left” custom_margin=”||||false|false” custom_padding=”||||false|false” global_module=”23371″ saved_tabs=”all” locked=”off” global_colors_info=”{}”]<\/p>\n \t\t [\/et_pb_text][et_pb_text _builder_version=”4.24.2″ _module_preset=”default” header_font_size=”36px” custom_padding=”|4%|||false|false” global_colors_info=”{}”]<\/p>\n CSU.
