The May beetle is a common type of beetle known for its appearance in late spring or early summer. You might often see these beetles buzzing around outdoor lights during this time. Some characteristics of May beetles include:

  • Brown or dark-colored body
  • Size ranging from 0.5 to 1 inch long
  • Ability to fly and crawl

May beetles are generally harmless to humans, but they can be a nuisance because of their large numbers, and in some cases, they can damage the roots of plants.

Beetle Larvae

When it comes to beetle larvae, these baby insects undergo a process called metamorphosis, turning from larvae to fully-grown beetles. A comparison of may beetles and beetle larvae shows some key differences:

Feature May Beetle Beetle Larvae
Size 0.5 to 1 inch long Smaller, varying by species
Appearance Brown or dark-colored body Whitish or cream-colored body
Mobility Can fly and crawl Limited crawling, mostly burrowing in soil

Beetle larvae are found in soil, feeding on the roots of plants, which can sometimes harm the plants as they grow. As they mature, they will eventually emerge and adopt the flying capabilities of adult beetles.

Letter 1 – Waved Light Fly


Subject: Stumped on fly (?) ID
Location: Galesburg, IL. USA
May 27, 2013 11:55 pm
Haven’t seen one of these in this area, Galesburg, IL, before. Was sleeping with wings open under outdoor lights along with the usual moths, and etceteras. Shot around midnight, Memorial Day. The wing span is close to 1.25” across. Thanks for any assistance.

Waved Light Fly

Hi Susurra,
It took us a bit of searching, but we eventually identified your Waved Light Fly, Pyrgota undata, thanks to images posted to BugGuide.  This is a new species and we do not have a classification for it except “Flies” as a broad order category.  None the subcategories that we could possibly classify it into have common names.  According to BugGuide, it is in the family Pyrgotidae, superfamily Tephritoidea, no taxon “Acalyptratae” and then the order Diptera, the Flies.  So, though the species has a common name, no subcategories have common names.  BugGuide does state this about the life cycle:  “Life history: Female lights on a feeding May beetle, causing it to take flight. Pyrgotid then oviposits into beetle’s back while soft parts are exposed in flight. Flies usually attack female beetles only and may pursue them under lights. Larvae is about 1 cm long, takes about 14 days to kill host beetle and then consumes entire interior. Fly pupates inside host remains and pupates there, emerges following spring.”  Thank you for this interesting submission and for providing a photo of an underrepresented species for our site.  

Thank-you. I’ve photographed a lot of insects, especially insects that geographically
don’t belong in this area, i.e. blue cycad butterflies. Never saw that particular fly before.
The closest ID was in the bee fly family, no exact match & this had no tufts of hair on it’s body.
I’ll forward some other photos of the same fly after I ‘clean them up’ just a bit for clarity, so you
can have some other images for the site.

We will be away for ten days, so we hope your photos don’t get lost in the backlog we expect upon our return.

Perfect time for me to procrastinate. Also, I remember the night I first saw the wave light fly,
there were a lot of ‘June’ bugs then. Maybe that’s what led it to here. Just maybe.

Letter 2 – Waved Light Fly dispatched unnecessarily


wasp,hornet or bee?
Location: hope mills, north carolina
May 10, 2011 7:52 pm
I was watering my flowers in Hope Mills,North Carolina and this bug flew out and tried to sting me in the face, It was very agressive. I looked in flowers for a nest but none. So I was wondering what kind it is?
Thanks Lisa

Waved Light Fly

Dear Lisa,
It took us a bit, but we finally identified your mystery creature as a Waved Light Fly,
Pyrgota undata, after browsing through images posted to BugGuide. This is a new species for our website and it doesn’t fit into any of our existing subcategories of Flies, so we will either archive it generally or create a new subcategory.  We wish you had submitted a photo of a living specimen.  The impression it gave that it was trying to sting you was a misunderstanding as the Waved Light Fly cannot sting nor does it bite, hence it was killed needlessly.  According to BugGuide:  “Life history: Female lights on a feeding May beetle, causing it to take flight. Pyrgotid then oviposits into beetle’s back while soft parts are exposed in flight. Flies usually attack female beetles only and may pursue them under lights. Larvae is about 1 cm long, takes about 14 days to kill host beetle and then consumes entire interior. Fly pupates inside host remains and pupates there, emerges following spring.”

Waved Light Fly

Dear Gary,
This is not a Wasp.  It is a Waved Light Fly,
Pyrgota undata, in the  family Pyrgotidae, and we have one other example in our archives, but it is only classified as a Fly and is not subcategorized.  Thanks to your submission, we are going to create a subcategory for the family Pyrgotidae which does not have a common name.  These flies are parasitoids, and according to BugGuide: “Life history: Female lights on a feeding May beetle, causing it to take flight. Pyrgotid then oviposits into beetle’s back while soft parts are exposed in flight. Flies usually attack female beetles only and may pursue them under lights. Larvae is about 1 cm long, takes about 14 days to kill host beetle and then consumes entire interior. Fly pupates inside host remains and pupates there, emerges following spring.” 

Wow! Thank you so much for the information. What an interesting way to propagate!!
I really appreciate your help and will make a contribution on your website to partially return the favor.
Best regards,
Thanks Gary,
That is very generous of you.

  • One of these landed on my windshield just last week while waiting at the bus stop in northern VA. I thought it was some freak sort of wasp and promptly put all the windows up to keep it out of the car. Apparently, my fear was unnecessary. Thanks for quelling my panic!

    Oh my goodness! Never heard of the Pyrgotidae! Thank you so much for this site- i learn something everytime i visit. Thanks also for all the great links to other sites. You have expanded my world. I am even learning a little Portuguese, courtesy of Cesar Crash.
    Thank you, thank you very much

    • Thanks for the compliment. We are very proud of our relationship with our sister site in Brazil, Insetologia, and Cesar Crash is a frequent contributor to our site, though we do feel a little guilty in that the relationship is somewhat one-sided as we don’t really assist Cesar with any of his difficult identifications.
