- 0:20many species, most notably the monarch butterfly, but what exactly is a
- 0:25Host plants and why do the matter? Let's dive in and find
- 0:27out more. Host plant are specific plants or plant families that insects
- 0:33have coevolved with and rely on for food and shelter. Host plants,
- 0:36are vital for the reproduction of these insects as at least one
- 0:40life stage solely relies on the host plants, for survival. For example,
- 0:45even though milkweed, produces thick, toxic sap, monarch butterflies exclusively lay their
- 0:50eggs only on milkweed plants, and the caterpillars specialize in eating milkweed
- 0:55leaves during their development. Adult butterflies can feed on nectar from various
- 1:00flowering plants, but their caterpillars can only consume milkweed, which in turn
- 1:05gives the caterpillars and butterflies their color and main defense of being
- 1:09mildly toxic and having a terrible taste to predators. In addition to
- 1:13monarch though, several other insects rely on species of milkweed, for their
- 1:17survival as well. Red milkweed beetles Tetraps tetraphalmus are a species of
- 1:23longhorn beetle that are commonly found on common milkweed. Red milkweed beetles
- 1:28only eat Milkweed and do not harm any garden plants. They are
- 1:31also harmless to monarch eggs, caterpillars, and butterflies. Large milkweed bugs, Oncopeltus
- 1:38fasciatus, feed on the seeds and leaves of Milkweed and help disperse
- 1:42the milkweed seeds by opening the pods. They migrate south to the
- 1:46Gulf states for the winter and migrate back north in the spring.
- 1:50Swamp milkweed leaf beetle Libidimera Clivocalis may look like an oversized ladybug
- 1:56at first glance, but these rounded beetles are a type of leaf
- 1:58beetle. They rely on both swamp milkweed and Common
- 2:01milkweed, Milkweed Tussick Moth Caterpillars UK Edis Eagle rely solely on milkweed
- 2:07just like monarchs. They have a distinctive and protective hairy appearance that
- 2:11causes a rash if handled. All of these insects help make up
- 2:16a healthy and biodiverse milkweed ecosystem. They each serve a purpose, they
- 2:21coexist, and they are beneficial to the environment. In our region there
- 2:25are a few species of milkweed that grow well and are recommended
- 2:28for our area. Common Milkweed,
- 2:31Asclepias syriaca has pink to purple flowers that bloom in a 2-3-inch
- 2:36rounded cluster called an umble. They need full sun with well-drained soil.
- 2:40They bloom from June to August. This plant grows All
- 2:44and can be an aggressive spreader, so care should be taken when
- 2:47selecting sites to plant this. Swamp milkweed, Asclepius incarnata, has rosy, purple
- 2:53flowers clustered at the top of tall stems. As the name implies,
- 2:56these prefer medium to moist soil. They bloom from June to October.
- 3:01Horald milkweed Asclepius verticillata is very dainty compared to the other two
- 3:05milkweed species described so far. It has a single stem with wharled,
- 3:10narrow leaves and small white flowers in flattened clusters at the top
- 3:14of the stem. They bloom from May to September in dry or
- 3:17sandy soils. All milkweed is toxic and should be kept away from
- 3:22pets and children. It is also always recommended to wear gloves when
- 3:25working around milkweed and to avoid contact with the sap. Despite this,
- 3:30they are vital to pollinators and serve as important host plants, so
- 3:33they are key native species. If you would like to learn more,
