Ambrosia beetles
Ambrosia beetles
Curculionidae (Scolytinae)
Ambrosia beetles are tiny wood-boring weevils that farm symbiotic fungi inside stems and trunks. The first sign is often wilting or die-back on a branch that still looks green, paired with fine sawdust or toothpick-like strands at the base. They target stressed, thin-barked trees and shrubs across temperate to subtropical zones. Catching them early matters because galleries disrupt vascular flow and open pathways for decay organisms.

Armadillo
Armadillo
Dasypus novemcinctus
If your garden beds look like something dug random holes overnight — 3 to 5 inches deep, conical, scattered with no pattern — an armadillo was there. They do not eat plants directly. They are after grubs, earthworms, beetle larvae, and soil insects, and they find them by smell, punching through mulch and root zones to get them. A food forest with rich biology and deep mulch is an armadillo paradise. One animal can excavate dozens of holes per night and uproot seedlings, bulbs, and shallow-rooted plants without ever intending to.

Cuban tree frog
Cuban tree frog
Osteopilus septentrionalis
Cuban tree frogs are large nocturnal hylids that climb walls, enter sheds, and colonize downspouts and nursery houses. They eat native tree frogs and small vertebrates, and their skin secretions irritate mucous membranes. In horticulture they are a nuisance around irrigation boxes, shade houses, and porch lights that concentrate insect prey. Where they are invasive, management favors exclusion and humane removal following local wildlife rules.

Cucumber Mosaic Virus
Cucumber Mosaic Virus
Cucumber mosaic virus (CMV)
If leaves show irregular yellow-green mosaic patterns, distorted crinkled growth, and stunted plants despite good care, Cucumber Mosaic Virus is a strong suspect. CMV is the most widespread plant virus in the world — it infects over 1200 plant species including cucumbers, tomatoes, peppers, squash, beans, spinach, and many ornamentals and herbs. There is no cure once a plant is infected. Aphids spread it in seconds while feeding — a single aphid probe transmits the virus before any aphid control can stop it. Remove infected plants immediately to reduce spread to healthy ones.

Cutworms are caterpillars that clip seedlings at soil line, sometimes dragging small plants underground to feed. They feed at night and hide just under the soil surface by day, which makes blame fall on birds or rabbits first. Outbreaks follow weedy fallow, fresh tillage, or thick mulch that gives them cover. They occur on vegetables, grains, and nursery transplants across temperate to subtropical production zones.

Overwatering root rot
Overwatering root rot
Pythium, Phytophthora, Rhizoctonia (complex)
Overwatering root rot is a syndrome where roots sit anaerobic long enough for opportunistic oomycetes and fungi to colonize fine roots, causing wilting despite wet soil, browning at the crown, and sudden collapse of seedlings. It is extremely common in containers without drainage, in heavy clay with poor grading, and in automated irrigation that never dries between cycles. Fixing water first beats chasing pathogens that return the moment media stays soggy again.

Slugs
Slugs
Gastropoda
If seedlings disappear overnight, leaves have ragged irregular holes with no insect in sight, and there is a silvery slime trail on soil or leaves in the morning — slugs were there. They feed at night and hide during the day under debris, boards, dense mulch, and soil cracks. Slugs are essentially snails without shells, which means they dry out faster and are more dependent on moisture and cover. A wet spring or summer night followed by missing seedlings is the classic scenario. They can completely destroy a seedling in one night and will return to the same plants repeatedly until stopped.

If leaves have ragged holes, seedlings disappear overnight, and you find silvery slime trails on soil and leaves in the morning — snails were there. Snails are slugs with shells, which means they survive drier conditions and are harder to dehydrate than slugs. They hide in shells during dry periods and emerge after rain or irrigation. The shell also makes them slightly slower to move than slugs but better at surviving hostile conditions. In warm humid climates like Florida, snails are active much of the year.

If new growth is curling, yellowing, sticky, or chewed, swede midge may already be on the plant. This pest often builds quietly, then damage appears all at once. Feeding stress weakens growth, reduces yield, and opens the door to secondary disease. Early cleanup is much easier than fighting a full population surge later.

Sweet Potato Weevil
Sweet Potato Weevil
Cylas formicarius
If plants are wilting, notching at the edges, or fruit and roots show hidden feeding damage, sweet potato weevil may be the cause. Adults chew above ground while larvae often feed out of sight inside soil, stems, or fruit. Damage builds quietly, then plants crash fast when roots are heavily hit. Act early so a small weevil problem does not become a season-long infestation.

Tea scale
Tea scale
Fiorinia theae
Tea scale is a small armored scale that infests the underside of camellia, holly, and many other evergreen leaves, causing yellow speckling visible from above and premature leaf drop when heavy. Males are narrow and white; females are darker and broader under cover. It thrives in humid subtropical to warm temperate landscapes and greenhouse collections.

Tent Caterpillar
Tent Caterpillar
Malacosoma spp.
If leaves look shredded overnight or fruit has fresh chew holes, tent caterpillar may be feeding right now. These larvae can eat fast and strip a healthy plant in a short window. Young stages are easy to miss, then damage suddenly explodes as they grow. Catch them early to avoid severe defoliation and contaminated harvests.

Texas Citrus Mite
Texas Citrus Mite
Eutetranychus banksi
If leaves look dusty, speckled, bronzed, or curled without obvious chewing, texas citrus mite is a likely suspect. Mites are tiny but can multiply fast, especially during heat and dry air. Plants lose vigor as feeding drains cell contents from leaves and tender growth. Early action matters, because heavy infestations can spread through a bed in days.

Treehoppers
Treehoppers
Membracidae
Treehoppers are bizarrely shaped hemipterans that often sit motionless on stems, sometimes in maternal groups guarding egg masses. They pierce phloem and excrete honeydew that grows sooty mold. Most species are minor alone, but dense aggregations can stress young shoots on legumes, orchard trees, and ornamentals from tropical to temperate climates.

Twig borers
Twig borers
Multiple Coleoptera and Lepidoptera (twig-boring guild)
Twig borers are larvae of small moths or beetles that tunnel inside shoots, causing flagged dead tips, sawdust at entry holes, and weakened scaffold on fruit trees and ornamentals. Damage is often localized to current-year wood. Hosts range from stone fruit to pecan to roses depending on species complex in your region across temperate to subtropical production zones.

Walnut Husk Fly
Rhagoletis completa
If leaves show trails, fruit turns soft, or roots collapse from inside, walnut husk fly may already be feeding. The larval stage does most of the damage, often hidden where you cannot see it at first glance. By the time yellowing or rot appears, feeding may be well underway. Move quickly when symptoms begin to prevent another wave of eggs and larvae.

White grubs
White grubs
Scarabaeidae larvae
White grubs are the soil-dwelling larvae of scarab beetles, creamy white with brown heads and three pairs of thoracic legs in a C-shape. They consume roots of turf, ornamentals, and row crops, producing irregular dead patches and easily lifted sod. Adults may be Japanese beetles, June beetles, masked chafers, or other regional scarabs. Populations cycle with weather and adult feeding and oviposition habits.

White peach scale
White peach scale
Pseudaulacaspis pentagona
White peach scale is a diaspidid armored scale that forms dense white covers on bark and sometimes fruit of stone fruit, pome fruit, and many ornamentals. Heavy infestations cause limb dieback and reduce fruit finish. Crawlers spread to new wood in multiple generations per year in warm climates. It is a global pest wherever hosts are grown in temperate through subtropical orchards and landscapes.

White Rot
White Rot
Sclerotinia sclerotiorum
If leaves, stems, or fruit suddenly look spotted, sunken, or rotting, white rot may already be active. This problem often starts small, then spreads across healthy tissue before most growers realize how serious it is. Warmth, moisture, and crowded foliage usually speed it up. Treat early, because waiting even a few days can turn a manageable infection into major crop loss.
