Your letter to the bugman:  Dear Bugman, my friend found this moth resting on his window and I got to take some photos. I searched several archives of known moths in the area and I found similar moths but nothing that was quite right. Can you please identify this moth for me? The date is June 15th and the moth was found around 1pm. It has been very wet the past few weeks which has been followed by high 80 to mid 90 degree weather for the past three or four days.

Male Polyphemus Moth

Dear BigMothus,
This impressive creature is a male Polyphemus Moth.  When disturbed, it flashes its large eyespots, often frightening a potential predator with the possibility of getting eaten.

That’s amazing! I had heard of them but I had no idea I was in the presence of such a distinguished creature. Thank you for responding so quickly, not knowing was eating at me!

Tulip Tree Silkmoth

Dear Jan,
This looks to us like a male Tulip Tree Silkmoth,
Callosamia angulifera, and it is pictured on BugGuide.  It is one of the Giant Silkmoths in the family Saturniidae.  Giant Silkmoths only live a few days, long enough to mate.  They do not feed as adults.

Your letter to the bugman:  I don’t need this identified but thought I would share! Found this gem last night attached to my screen door. I was amazed by it’s beauty. After looking online I figured out it is a Luna Moth. Woke up this morning and he was on the wooden door frame of my screen door so I got some better pics of it. The pics I took last night didn’t turn out very good so I was excited when I saw he was still here!

Luna Moth

Dear Gene,
We are so excited that your submission is our first Luna Moth posting of the year, though one can only guess how many Luna Moth submissions arrived between April 21 when Daniel last checked his emails and now.  Canadian sightings are occur around June, and our earliest sightings, sometimes as early as January or February, are generally from Texas and Florida.

Your letter to the bugma:  We have noticed these beautiful caterpillars at the same time each year. This year quite a few of them have “eggs” attached to them. It looks like these caterpillars die. Could this be a parasite wasp?

Cabbage Emperor Moth Caterpillars with parasitoid Wasp Pupae

Dear Jenny,
We believe we already responded to a comment you posted to another posting on our site.  Alas, these Cabbage Emperor Moth Caterpillars,
Bunaea alcinoe, appear to have fallen victim to a parasitoid Wasp, probably a Braconid or Chalcid Wasp.  According to Siyabona Africa:  “The Bunaea alcinoe (common emperor) caterpillars mentioned above, had been discovered by a tiny specie of the large family of parasitoid Braconid wasps (Braconidae). The adult wasp had penetrated the live caterpillar(s) with her ovipositor and laid eggs inside the caterpillar. The eggs had hatched into larvae which fed within the caterpillar.  The larvae, on reaching full size, cut their way out of the caterpillar and formed tiny, white cocoons, within which they pupated, on the outside of the caterpillar. Within a few days the mature wasps cut their way out of the cocoons to repeat the cycle. The caterpillars, denuded of their nutrients and depending on their rate of leaf consumption, slowly shrivel and die.”

Many thanks for this detailed and interesting reply. Much appreciated.
Kind regards
