| 0007078 | red oak borer | Enaphalodes rufulus | A mating pair |
| 2109025 | harvester ants | Pogonomyrmex spp. | sometimes confused with Texas leaf-cutting ants |
| 1150137 | green lynx spider | Peucetia viridans | |
| 1150087 | forest tent caterpillar | Malacosoma disstria | Egg masses typically encircle a small branch and the larvae hatch in the early spring as the leaves are unfolding from their buds. |
| 0007077 | red oak borer | Enaphalodes rufulus | When adult red oak borers begin to emerge in late June, populations are so high that it is easy to find mating pairs on understory vegetation and on the trunks of oak trees. |
| 1150131 | 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. |
| 0007080 | red oak borer | Enaphalodes rufulus | Larval tunnels of the red oak borer rendered oak lumber basically unusable. |
| 0007053 | cecropia moth | Hyalophora cecropia | near Russelville, Arkansas, on June 26, 2001. |
| 0007054 | cecropia moth | Hyalophora cecropia | near Russelville on June 26, 2001. |
| 0007055 | cecropia moth | Hyalophora cecropia | near Russelville, Arkansas, on June 26, 2001. |
| 0007041 | canna | Canna spp. | Leaves are a good food source for some insects and insect feeding can make the plants unattractive. |
| 2109027 | catalpa sphinx | Ceratomia catalpae | larva can show considerable color variation |
| 0007040 | canna | Canna spp. | A common landscape plant in the southern United States. They are easy to grow and produce showy flowers. |
| 0007076 | red oak borer | Enaphalodes rufulus | It is at outbreak levels in the area and characteristic signs of attack include "wet spots" where young larva are feeding under the bark. |
| 0007069 | poplar petiolegall aphid | Pemphigus populitransversus | Produces characteristic marble-sized galls on the petiole of cottonwood leaves. |
| 0007070 | poplar petiolegall aphid | Pemphigus populitransversus | When a gall is cut open, numerous aphids can be found inside. |
| 0007068 | twig girdler | Oncideres cingulata | The adults will feed or chew on the bark of severed branches causing characteristic "scratch" marks on the twigs. |
| 0007071 | question mark | Polygonia interrogationis | It is a common butterfly in the southern United States. The larva of this brushfooted butterfly is covered with spines and elm is its preferred host. |
| 0007058 | truncated true katydid | Paracyrtophyllus robustus | The katydids were found on many other objects, including the trunks of trees at spot |
| 1150123 | 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. This mature larva was found on the ground, probably searching for a pupation site. |
| 1150120 | 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. |

| 2109023 | starburst needle gall | Taxodiomyia spp. | |
| 0007043 | larger canna leafroller | Calpodes ethlius | Mature larvae are nearly two inches long. Note the network of tracheae that originate from the spiracles and the characteristic dark triangle on the frontal region of the head capsule. |
| 0007075 | 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. |
| 0007059 | common true katydid | Pterophylla camellifolia | Photographed in June 2001. The northern true katydid is green rather than the brown color of the truncated true katydid. |
| 0007060 | yellow garden spider | Argiope aurantia | Large female at truncated true katydids outbreak |
| 0007056 | truncated true katydid | 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 |
| 1150142 | 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.

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. |
| 1150089 | 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 |

| 1150116 | tersa sphinx | Xylophanes tersa | typical emerged adult |
| 1150117 | 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.

| 0007072 | question mark | Polygonia interrogationis | Chrysalis is rather drab and well camouflaged, except for about eight bright silver spots. They usually attach their posterior end to a leaf with silk threads and hang from the leaf until they emerge as adults. |
| 0007073 | question mark | Polygonia interrogationis | A typical anglewing. It is a fast and strong flier and has beautiful markings on the uppersides of the wings. |
| 0007074 | question mark | Polygonia interrogationis | The undersides of the wings resemble a dead leaf and bear the silver comma and dot typical of this species. |
| 0007061 | yellow garden spider | Argiope aurantia | Web with captured truncated true katydids |
| 0007066 | 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. |
| 0007044 | larger canna leafroller | Calpodes ethlius | When a larva is not feeding, it will fold a canna leaf over itself. The folded leaf is secured with silk threads. |
| 0007045 | larger canna leafroller | Calpodes ethlius | After about 10-14 days of feeding, the larva pupates. Notice the silk thread that secures the pupa on a pad of silk inside a folded canna leaf. Also note the characteristic anterior spine (right) and the enclosed proboscis extending beyond the cremaster (left). |
| 0007046 | larger canna leafroller | Calpodes ethlius | After the adult emerges, the empty pupal skin is left behind. |
| 0007047 | larger canna leafroller | Calpodes ethlius | A typical skipper and not particularly showy |
| 0007042 | larger canna leafroller | Calpodes ethlius | A typical skipper larva having the constricted "neck" behind the head. |
| 0007079 | red oak borer | Enaphalodes rufulus | Frass associated with the emergence of adult borers often collects on the leaves of understory vegetation. |
