A slender, fast-running beetle with unusually short wing covers that leave much of its flexible abdomen exposed, often curling its tail upward like a scorpion when alarmed.
beetle
Treehopper
A small, oddly shaped sap-feeding bug best known for an enlarged, often bizarre pronotum extending backward over its body, sometimes shaped like a thorn, leaf, or spike.
true-bug
Lace Bug
A tiny, flattened true bug with delicately sculpted, lace-like wings resembling fine netting, the lace bug feeds in colonies on the undersides of leaves, leaving a stippled, bleached pattern on foliage.
true-bug
Aphid
A tiny, soft-bodied, pear-shaped insect that clusters in dense colonies on plant stems and leaf undersides, feeding on sap through needle-like mouthparts and often coated in sweet honeydew.
