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. |

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. |

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. |

| 1255001 |
oak casebearer |
Coleophora lutipennella |
Overwintering larva in its pergamentous whitish case. If opened (case), dark brown caterpillar with shiny black head is found inside. Larva feeds with the bud interior almost completely boring inside the still closed bud. Overwintering loci are always on twigs in sheltered crevices near the buds. Case grows as larva gets bigger and after the pupation moths emerge in late spring - summer. Common pest sometimes causing mild damages on pedunculate oak (Quercus robur) stands in Croatia. |
| 1627006 |

| 1627021 |

There are a few caterpillars that should not be handled because of their stinging spines. Contacting the spines of a saddleback caterpillar is every bit as painful as a bee sting. |

| 1435194 |
hag moth |
Phobetron pithecium |
This dark brown, hairy caterpillar is easy to recognize because of the nine pairs of fleshy appendages protruding from its body. The hagmoth larva is another of the slug caterpillars which have urticarial hairs and can produce serious dermatitis (stinging rash) when handled. Hagmoths are usually found singly feeding on low branches of shrubs and deciduous trees (oaks, other hardwoods, etc.). |

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. |
| 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. |
