Dudleya brittonii may encounter various pests during its life cycle. Below are some of the most common pests you might find affecting this succulent:
Aphids are tiny sap-sucking insects that can appear in clusters on new growths and stems. They can be green, black, or even pinkish in color.
Identification: Look for small insects on the undersides of leaves or near flower buds. You may also notice sticky honeydew residue on leaves, which attracts sooty mold.
Mealybugs are small, white, cottony-looking insects that tend to cluster in hidden areas such as leaf joints or stem bases.
Identification: These pests leave behind a waxy coating and can lead to yellowing leaves or stunted growth.
Scale insects resemble small bumps or shells on plant stems and leaves. They are often brown or gray and can be challenging to spot due to their protective coverings.
Identification: If you see tiny shell-like spots on your Dudleya, it might be a scale infestation. Look for discolored patches on leaves as well.
Spider mites are not insects but arachnids that thrive in hot and dry conditions. They feed on plant sap and can cause leaf damage.
Identification: Look for tiny webbing on the underside of leaves and fine yellow speckling on foliage.
While primarily a nuisance rather than a direct threat to the plant’s health, fungus gnats larvae feed on organic matter in potting soil and can damage roots.
Identification: Adult gnats are small black flies that flutter around pots, especially if there’s damp soil present.
