arachnidSoil Mite
A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.
arachnid
Spider Mite
A speck-sized arachnid that spins fine silk webbing across infested leaves as it pierces plant cells for their contents, leaving behind a telltale stippled, bronzed appearance. Populations can explode rapidly in hot, dry weather, making it a familiar garden and greenhouse pest.
arachnid
Two-Spotted Spider Mite
A near-microscopic mite that spins fine silk webbing over leaves as it feeds, leaving foliage stippled and pale.
arachnid
Flour Beetle

beetleBlister Beetle
An elongated, soft-bodied beetle with a distinctly narrow neck, often seen feeding in small groups on flowers, and known for releasing a defensive chemical from its leg joints when disturbed.
beetleTortoise Beetle
A small, flat, disc-shaped beetle whose expanded wing covers and pronotum hide its head and legs almost entirely, giving it the look of a miniature turtle shell crawling across a leaf.
