The elm sawfly is not considered a problem in forest situations, but can be a defoliator of shade and ornamental elm and willow trees. The elm sawfly is the largest North American sawfly with larvae reaching a length of almost two inches. The larvae pictured here were found feeding on an American elm tree in Bastrop, Texas (near Austin, TX) on May 2, 2002. Larvae are a yellowish-white color and possess a black dorsal stripe. While feeding, the larvae usually coil their posterior around a leaf or twig. At rest the larvae roll into a characteristic tight coil. The larvae spin tough, papery cocoons in the litter or just below the surface of the soil. |

giant bark aphid |
Longistigma caryae |
The giant bark aphid is the largest aphid in North America. During December 2001 and through most of March 2002, an outbreak of this aphid was found covering about the eastern quarter of Texas. They mainly attacked oak trees, especially live oak and water oak. Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002. |

This walkingstick is found in parts of the southern US. The male is much smaller than the female and when they are mating, the female carries the male. In fact the male is so small and well camouflaged, he is hard to see. When disturbed, they will give off a foul-smelling odor in the form of a fine mist. |

In expanding infestations, here stages of attack can be distinguished: stage 1 with green foliage, soft pitch tubes in the bark crevices and with the wood surface having a white color (without bark beetle galleries); stage 2 with fading or yellow crown, serpentine galleries under the bark, and the surface of the wood being brown in color; stage 3 with a red or maroon crown (or without foliage) and with small, circular exit holes in the bark. Olancho Region, Honduras |

Dendroctonus brevicomis |
Based on the open, branching gallery patterns and large exit holes, combined with the pattern of tree mortality (all trees in the same stage of foliage fade), we concluded that the primary bark beetle present was the western pine beetle, Dendroctonus brevicomis. This species is known to frequently kill drought-stressed pines in the Davis Mountains. We were unable to collect any adults to confirm the species. To my knowledge, however, the southern pine beetle has never been collected from the Davis Mountains, although it attacks ponderosa pine in Arizona and New Mexico |

Cimbex americana |
The elm sawfly is not considered a problem in forest situations, but can be a defoliator of shade and ornamental elm and willow trees. The elm sawfly is the largest North American sawfly with larvae reaching a length of almost two inches. The larvae pictured here were found feeding on an American elm tree in Bastrop, Texas (near Austin, TX) on May 2, 2002. Larvae are a yellowish-white color and possess a black dorsal stripe. While feeding, the larvae usually coil their posterior around a leaf or twig. At rest the larvae roll into a characteristic tight coil. The larvae spin tough, papery cocoons in the litter or just below the surface of the soil. |

red oak borer |
Enaphalodes rufulus |
Red oak mortality has been observed for the past several years (2001). Drought, shallow soils, hypoxylon canker, certain insects, and other factors have lead to this decline complex. |

Paracyrtophyllus robustus |
Defoliated post oak trees were found and checked in July 2001 as part of off-plot forest health monitoring. It was determined that an area of about 1000-2000 acres was impacted. |
| 0007057 |
truncated true katydid |
Paracyrtophyllus robustus |
Closer examination of damaged post oak trees revealed that a very unusual outbreak of the katydid was causing the defoliation. The katydids were found on post oak foliage and evidence of their feeding was very obvious |

giant bark aphid |
Longistigma caryae |
As aphids feed, they excrete a sticky, clear liquid known as honeydew that often forms a sticky coating on automobiles, picnic tables, lawn furniture, and plants underneath plants where aphids are feeding. A gray-black, sooty mold soon begins to grow on the sugar-rich honeydew, and it not only blocks sunlight and disrupts photosynthesis, but it can damage the finish on cars, chairs, tables or other objects. |
| 1150143 |
lady beetle |
|
Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002. |
| 1150144 |
Pandora sphinx |
Eumorpha pandorus |
The pandora moth is listed as a minor defoliator of plants in the grape family in Wagner, D. L., V. Giles, R. Reardon, and M. McManus. 1997. Caterpillars of Eastern Forests. USDA, FS. FHTET-96-34. Page 16. The larva occurs in an orange and a green color phase. The mature larva is about three inches long and the large, oval, white spiracle patches make the caterpillar quite showy. |
| 1150126 |
elm sawfly |
Cimbex americana |
The elm sawfly is not considered a problem in forest situations, but can be a defoliator of shade and ornamental elm and willow trees. The elm sawfly is the largest North American sawfly with larvae reaching a length of almost two inches. The larvae pictured here were found feeding on an American elm tree in Bastrop, Texas (near Austin, TX) on May 2, 2002. Larvae are a yellowish-white color and possess a black dorsal stripe. While feeding, the larvae usually coil their posterior around a leaf or twig. At rest the larvae roll into a characteristic tight coil. The larvae spin tough, papery cocoons in the litter or just below the surface of the soil. |
| 1150127 |
walkingstick |
Anisomorpha spp. |
This walkingstick is found in parts of the southern US. The male is much smaller than the female and when they are mating, the female carries the male. In fact the male is so small and well camouflaged, he is hard to see. When disturbed, they will give off a foul-smelling odor in the form of a fine mist. |
| 1150130 |
tersa sphinx |
Xylophanes tersa |
The naked pupa is usually found in the soil. |
| 1150084 |
forest tent caterpillar |
Malacosoma disstria |
The forest tent caterpillar occurs throughout the eastern United States and is a defoliator of a wide variety of hardwood trees. This is the tent caterpillar that does not make a tent! There is one generation per year and the insect overwinters in the egg stage. An unusual outbreak of the forest tent caterpillar occurred in East Texas in the spring of 2002 where some 125,000 acres of bottomland mixed hardwood forest were moderately defoliated. Because they do not defoliate all the trees in mixed deciduous stands, light defoliation may be difficult to see from the air. Moderate defoliation shows up from the air as a gray-green color. |
| 1150085 |
forest tent caterpillar |
Malacosoma disstria |
As the larvae grow, they molt as a group and a concentration of cast larval skins can often be found. |
| 1150086 |
forest tent caterpillar |
Malacosoma disstria |
The larvae don’t construct a characteristic tent like the eastern tent caterpillar. Instead, they construct silk webbing that lies flat on the surface of the tree’s trunk and branches. The colorful larvae are easily identified by the "keyhole" or "footprint" pattern on their dorsal surface. |
| 1150088 |
forest tent caterpillar |
Malacosoma disstria |
The larvae feed on sweetgum, tupelo gum, black gum, and various species of oak. |

giant bark aphid |
Longistigma caryae |
The giant bark aphid is the largest aphid in North America. During December 2001 and through most of March 2002, an outbreak of this aphid was found covering about the eastern quarter of Texas. They mainly attacked oak trees, especially live oak and water oak. Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002. |

twig girdler |
Oncideres cingulata |
Pencil-sized twigs of pecan, hickory, elm, and other tree species are commonly girdled in the fall. It is not unusual to see branches on the ground under attacked trees or to see broken branch "flags" hanging from the crown. |
| 0007067 |
twig girdler |
Oncideres cingulata |
By circling the branch many times, the adult female will cut the branch with a very neat and precise cut. The cuts are so unique that it is easy to tell when a twig girdler has visited the tree. |
