Earthworms are shifting their ranges northwards into forests between 45° and 69° latitude in North America that have lacked native earthworms since the last ice age. [3] Of the 182 taxa of earthworms found in the United States and Canada, 60 (33%) are introduced species, these earthworm species are primarily from Europe and Asia.
Eurema hecabe, the common grass yellow, [1] [2] is a small pierid butterfly species found in Asia, Africa and Australia. [1] [2] [3] They are found flying close to the ground and are found in open grass and scrub habitats. It is simply known as "the grass yellow" in parts of its range; the general term otherwise refers to the entire genus Eurema.
Earthworms are classified into three main ecophysiological categories: (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter e.g. Eisenia fetida; (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal ...
A mustard pour can be created by mixing a gallon of water with one third cup of ground yellow mustard seed. Pouring the solution slowly over the soil will drive worms to the soil's surface without harming the plants. [15] People with invasive worms on their property are advised not to move plants or soil from their property.
Winter temperatures can also reduce activity, while activity in maritime climates can continue through winter. [1] Lumbricus terrestris can strongly influence soil fungi, creating distinctive micro-habitats called middens, which strongly affect the spatial distribution of plant litter and litter-dwelling animals on the soil surface.

Are there risks to eating edible worms and insects? As with any food, there’s always risk involved. Like with animal livestock, insects can harbor disease-causing pathogens, including E. coli ...
In ecosystems, earthworms such as Lumbricus rubellus increase the rate of transfer between trophic levels by making it easier for plants to uptake nutrients. In food chains, earthworms such as Lumbricus rubellus are primary consumers whose role is converting the energy synthesized by photosynthetic plants into food for animals at higher trophic ...
Yellow bear on milkweed. It has a diet of a wide range of low-growing plants, including ground cover like grass and clover. The larvae are defoliators, skeletonizing the leaves they feed on, but only the late summer batch of caterpillars is plentiful enough to do much damage to crops.
