Large Milkweed Bug

Dear KathyG,
This is a Large Milkweed Bug, Oncopeltus fasciatus, and it is part of the rich diversity of insects that are associated with milkweed.  Large Milkweed Bugs will not harm your Monarch Caterpillars nor will they harm the plants, but they will reduce the number of viable seeds the plant produces because according to BugGuide:  “Seeds of milkweed plants.”  Like Monarchs, they benefit from the toxins produced by milkweed plants and like Monarchs, they sport aposomatic warning colors because according to BugGuide:  “In the course of feeding these bugs accumulate toxins from the milkweed, which can potentially sicken any predators foolish enough to ignore the bright colors which warn of their toxicity.”

Your letter to the bugman:  Found this indoors today,  it landed on my face and it smelled. Thought it could be a stink bug, but the red marking on its body remind me of a kissing bug.  Do kissing bugs smell? I don’t think it’s a west conifer seed bug since the head looks round, and I don’t think the legs were barbed but i’m not sure. I crushed it before getting a good luck at it.

Elm Seed Bug

Dear Jen,
This is not a Kissing Bug, but it is a problem nonetheless.  It is an invasive Elm Seed Bug, Arocatus melanocephalus, and according to BugGuide:  “Native to, and widespread in S. & C. Europe, established and spreading in w. NA” and “Can emit unpleasant odor, especially when crushed.”  BugGuide also notes:  “Doesn’t pose a threat to trees, but may show up indoors in huge numbers” and “Invades homes during summer, may stay through the winter.”

Mating Whitecrossed Seed Bugs

Dear Tony,
These are mating Whitecrossed Seed Bugs and according to BugGuide an alternate name is  “Ragwort Seed Bug” which we interpret to mean that it will feed on seeds of ragwort, reducing the subsequent generations of what is widely considered a weed, though according to Wikipedia:  “Although the plant is often unwanted by landowners because it is considered a weed by many, it provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. It also was the top producer of nectar sugar in another study in Britain, with a production per floral unit of (2921 ± 448μg)”.  Since Seed Bugs feed on seeds, they are not normally considered injurious to plants.  We do not provide extermination advice.

Hi Daniel
Hope you are not angry that I am contacting you again.  Why are some of the larger bugs turning white.  See the picture.  I don’t know if it is a young bug getting mature or a mature bug getting older.

Newly Metamorphosed Large Milkweed Bug

No Problem Susan.  The light individual is newly metamorphosed, and once the exoskeleton fully hardens, the color will darken.

Thank you.  I really am afraid of bugs.  this is a whole new experience for me.
Thanks for helping me.
Susan
