Frangipani caterpillars, often Pseudosphinx tetrio, can defoliate plumeria quickly because large larvae consume leaves fast. This section focuses on recognizing caterpillar feeding and deciding when control is needed.
Caterpillars and frangipani worms decision path: Confirm the defining evidence before changing care or applying a product. Confirm: Look for fresh chewing, missing leaf tissue, dark pellet-like droppings, and the caterpillar itself. Frangipani caterpillars are large, black with yellow bands, and have a red-orange head and tail horn. Start conservatively: Hand-pick when practical using gloves […]

The frangipani caterpillar, also called the plumeria hornworm or frangipani worm, is the large larva of the tetrio sphinx moth (Pseudosphinx tetrio). It can remove leaves quickly and look alarming, yet a healthy mature plumeria often recovers. Seedlings, cuttings, newly rooted plants, and stressed plants need more protection because they have less foliage and stored […]
Use this section when stems or branches show entry holes, frass, tunneling, soft internal tissue, wilting tips, or sudden collapse. Bore worm and borer problems often require confirmation, clean pruning, disposal, and sanitation more than ordinary surface spraying.
Plumeria borers decision path: Confirm the defining evidence before changing care or applying a product. Confirm: Look for a discrete entry hole, granular or sawdust-like frass, tunneling, localized softness, dieback, or collapse. Do not confuse normal scars or lenticels with an active hole producing fresh debris. Start conservatively: Isolate affected material when practical, mark the […]

The plumeria stem borer is the larval stage of a longhorn beetle that feeds inside branches and stems. Entry holes, frass, tunnels, wilting tips, internal damage, and sudden branch weakness are the important clues. Once larvae are inside the stem, ordinary surface sprays do not reach them. 1. Identify Borer DamageConfirm entry holes, frass, tunnels, […]
Use this section when adult beetles chew leaves or white grubs may be damaging roots in the potting mix or soil. Separate leaf chewing, root chewing, and stem tunneling before choosing treatment because beetles, caterpillars, borers, and root pests need different responses.
May/June beetles and other beetles decision path: Confirm the defining evidence before changing care or applying a product. Confirm: Look for irregular chewing, beetles feeding after dusk, and repeated overnight damage. Confirm the adult when possible because caterpillars, grasshoppers, and snails can leave similar holes. Start conservatively: Inspect after dusk and hand-remove adults when practical. […]

Grasshoppers chew irregular sections from leaves and tender growth, especially during warm weather or in exposed growing areas. This category helps separate grasshopper damage from caterpillar, beetle, and mechanical injury.
Grasshoppers decision path: Confirm the defining evidence before changing care or applying a product. Confirm: Look for large irregular bites from leaf margins and directly observe a grasshopper, especially during morning warmth. Similar chewing without the insect may come from beetles or caterpillars. Start conservatively: Hand-remove when practical, protect young plants with suitable screening, and […]

Use this guide when plumeria leaves, buds, flowers, or tender tips show large irregular chewing. Confirm an active grasshopper or other large chewer before treating because old holes remain after the insect has left. Identify the Damage Choose Treatment Prevent a Return 1. Confirm Grasshopper Damage Clue What it suggests Large irregular holes or missing […]
Root weevils may damage plumeria as larvae feeding in the root zone and as adults chewing leaves. This category helps connect leaf notching, poor root performance, and plant decline when other causes do not explain the symptoms.
Root weevils decision path: Confirm the defining evidence before changing care or applying a product. Confirm: Repeated scalloped notches on leaf edges suggest adult feeding; weak growth plus cream larvae with brown heads around roots strengthens the diagnosis. Leaf notching alone does not prove damaging root larvae are present. Start conservatively: Collect nocturnal adults when […]

Use this guide when plumeria leaves show repeated edge notching or roots contain pale C-shaped larvae. Adult leaf feeding and larval root feeding require different responses, so confirm the life stage before treating. Identify Root Weevils Choose Treatment Prevent a Return 1. Separate Adult and Larval Evidence Clue What it suggests Repeated scalloped notches along […]
Leaf miners tunnel between leaf surfaces and leave pale winding trails or blotches. This section helps identify mining damage so it is not confused with fungal spots, nutrient symptoms, or surface feeding.
Leaf miners decision path: Confirm the defining evidence before treating. Confirm: Confirm winding tunnels or expanding blotches within the leaf, sometimes with a thin dark line of frass. Surface scars, chewing holes, and fungal spots are not mines. Start conservatively: Remove only heavily mined leaves when the plant has enough healthy foliage, seal discarded material, […]

Use this guide when plumeria leaves develop winding tunnels, pale tracks, or irregular translucent blotches. First decide whether the mine is active; old trails remain after the insect is gone.
