My friend from the garden club took a picture of this beetle. It is quite beautiful, but we don’t know what it is. It’s a very urban area.

Dear LinaJM,
This diminutive beauty is not a beetle.  It is an Ailanthus Webworm Moth.

We are wondering if this is a milkweed bug? Or “other”

Hello,
For the past few summers we have seen these fancy bugs here in North Texas. They are a golden orange with black rimmed white spots. The color is all around their bodies not just the top area. They are slender carrot shaped. Google suggests they may be long horned beetles. And they might be, but I haven’t seen a photo that matches them exactly. My son things they might be some type of moth. They are rather delicate. I’ve attached a photo. Anything you can tell us is appreciated. Thank you very much.
Best regards!

Your son is correct.  This Ailanthus Webworm is a species of Ermine Moth.

Dear Jess and Liam,
These are mating Ailanthus Webworm Moths, a native species that has adapted to feeding on the invasive, exotic, noxious weed tree known as the Tree of Heaven.

Hello What’s That Bug!
I think I photographed an ornate bella moth (or rattlebox moth) but it just doesn’t look right to me. The black and white patterns along the sides are very different from the “normal” rattlebox moths seen in our area and it also appears to have touches of purplish black on the back of the neck. This bug was photographed at Seacrest Scrub Natural Area in Boynton Beach, Florida. What do you think? Is it a rattlebox moth that has just decided to be “different”? Thanks for helping us identify all things creepy and crawly – and in this instance, wildly colorful!

Ailanthus Webworm Moth

Dear Ann,
This is an Ailanthus Webworm Moth, NOT a Rattlebox Moth.

Thank you so much for correcting me on the identity of this bug. I’ll let the natural area land manager know – this may be a new species for Seacrest Scrub Natural Area. Appreciate all you do!

Hi again Ann,
Though this is a native species, it has adapted to eating the invasive, exotic Tree of Heaven,
Ailanthus altissima, which might have gotten established in the Seacrest Scrub Natural Area.  If that is the case, those in charge should attempt to eradicate this noxious tree that is invading native open space across the continent.

Once again, thanks for the additional information about this moth. Our Department works hard to keep the natural areas free of invasive, nonnative plants. However, this particular natural area is surrounded by homes landscaped with lots of exotic plants – so I suspect the adult moths feed in the natural area while the caterpillars feed in the yards adjacent to the natural area.

Hi, This little guy or gal was on the wall outside my door this afternoon. Any ID would be helpful. Far more interesting than the thousands of tropical bagworm moths that have been hanging out of late.

Dear Mark B,
This little beauty is an Ailanthus Webworm Moth, a native species that has adapted so that the caterpillars will feed on the leaves of the invasive, exotic Tree of Heaven.
