Your letter to the bugman:  Hi, I have been finding these guys lying on their back in my back garden regularly (4 in the last 2 days). I thought they may have been honey bees.
I flipped them all back onto their feet only for them to roll back over.  It has been unusually warm here.
They are around 20mm in length.
I am a little concerned by the number of them appearing in my back garden because my 2 young children play there regularly.
Thanks in advance.

Horse Fly

Dear Kev,
This sure looks like a Horse Fly to us.  The wing venation pattern matches the diagram posted to BugGuide.

Subject:  Ant/Wasp like creature found on window

Your letter to the bugman:  It was around as big as the tip of my index finger (not including the wings). This wasp/ant like creature was all brown except for its abdomen, which was a darker shade of brown. It had a retractable stinger, I saw it and has black and white wings. I saw it on the opposite side of my window facing outside my house. I saw it on a cloudy hot summer day around dusk time, around the end of June. I am curious to know what kind of species it is, and if it is dangerous or not. I cannot find anything about it on the Internet, maybe it is a new species? Thank you!

Picture Winged Fly

This is neither an Ant nor a Wasp.  It is a Fly.  More specifically, it is a Picture Winged Fly, Delphinia picta.  It is not dangerous.

Your letter to the bugman:  Hello again Mr. Bugman,
I found this mothy fellow hanging out on a noodle bar.  He or She was rather big and rather beautiful and stay lovely and still while I took a few glamour shots.
Would love to know exactly what type of moth he or she is.

White-Edged Hunter Hawkmoth

Dear Adam,
This is a Hawkmoth or Sphinx Moth in the family Sphingidae, and we began our identity search on Farangs Gone Wild, but alas, none of the moths looked correct, so we turned to the Sphingidae of the Eastern Palaearctic where we found what we believe is your species, the White-Edged Hunter Hawkmoth,
 Theretra pallicosta.  We then returned to Farangs Gone Wild and clicked on the orange colored thumbnail for the species which led us to the species page that also included a dark colored individual like the one in your image.  Additional supporting images are on iNaturalist and Sambui Butterflies.

Wasp Moth

Hi Len,
This Tiger Moth in the subtribe Euchromiina, the group commonly called Wasp Moth, has eluded us in terms of a species identification, but we believe based on this image on Revolvy representing the genus
Cyanopepla, and this image on Bold Systems that the genus Cyanopepla might be correct.  We will contact Arctiid expert Julian Donahue to get his opinion.  Your images are gorgeous.

Wasp Moth

Thank you for your response and compliment!  I’d love it if you’d keep me updated on any further identification of the genus.  I have more photos of unique and beautiful insects that I have photographed on my farm in Costa Rica that I’d be glad share with you if you’d like.
Pura Vida!

Julian Donahue provides an identification.
Hi Daniel,
This is Belemnia inaurata, presumably subspecies inaurata. Although Hampson treated it as an arctiid, it has been transferred to the Ctenuchina (now treated as a subtribe of the tribe Arctiini, subfamily Arctiinae of the family Erebidae–my ctenuchids don’t get any respect any more!)
This diurnal moth is frequently encountered in Costa Rica as it visits plants rich in pyrrolizidine alkaloids (PAs), such Ageratum (which this plant may be, if it’s blue) and Eupatorium (the latter has been split into multiple genera, such as Conoclinium and Chromolaena, both of which I have in my butterfly & moth garden).
Nice pics. Thanks for the break from witnessing the cascading collapse of everything our nation stands for.

Ed. Note:  Here is an image of Belemnia inaurata from FlickR.

Ox Beetle

Dear Paula & Milo,
This is at least our third identification request for a male Ox Beetle in the genus
Strategus submitted from the Dominican Republic (see also here) and we still do not have a conclusive species name.  Because it is pictured on a stamp on Conect, our best guess would be Strategus quadrifoveatus, but Scarabaeidae de Hispaniola lists four different species: Strategus barbigerus, Strategus inermis, Strategus oblongus and Strategus syphax without images, and does not include the species pictured on the stamp.

Your letter to the bugman:  Thought it was a Palo Verde but to far east.

Male Tile-Horned Prionus

Your case of mistaken identity is understandable.  This male Tile-Horned Prionus is in the same tribe as the Palo Verde Root Borer.  According to BugGuide:  “Huge longhorn, dark brown and shining. Antennae have 18-20 overlapping segments (male).”
