In late May and early June bagworms hatch from eggs that lie dormant overwinter in the bag of their mother. The evergreen bagworm has the ability to defoliate evergreen trees and shrubs like spruce, arborvitae, fir, junipers and pine. When given a chance, it will also feed on deciduous trees like maples, honeylocust, and crabapples.
Cliff Sadof, Purdue University professor of entomology and Purdue Extension pest management specialist, and Carrie Tauscher, state community and urban forester at the Indiana Department of Natural Resources, will lead three workshops on invasive forest pests that pose a significant threat to Indiana's urban and rural forests.
Invasive species are said to be the second leading cause of biodiversity loss, after habitat loss. This new lesson teaches students about the significant environmental and economic losses that can be caused by the introduction of invasive plant species. The lesson meets multiple Indiana science, natural resources, math, and social studies standards.
Many of the invasive plant issues we experience in the urban ecosystem is due to improper plant selection when landscaping our homes and businesses. Before you plant checkout alternative options to avoid invasive plant species
In the dead of winter, we occasionally have to pick up dead wasps around our house. The wasps are often found on the carpet in the basement. But not always.

Taking steps to knock out potential mosquito breeding sites can greatly reduce the risk of Zika and West Nile virus in Indiana as the local mosquito season ramps up, says Purdue University medical entomologist Catherine Hill.
