I took these pictures yesterday of what I originally thought was a Brown Marmorated Stink Bug, but after viewing pictures of them online I was unable to find any comparable color patterns.

Black Stink Bug

Black Stink Bug

Dear Zach,
You are correct that this is a Stink Bug in the family Pentatomidae, but we needed to research its identity.  Relatively quickly we located the Featured Creatures site indicating that this is a Black Stink Bug,
Proxys punctulatus, and this information is provided:  “The biology of the black stink bug, Proxys punctulatus (Palisot), is not well known. It has a broad geographical range in the Americas but does not appear to damage agricultural crops as do other more important pentatomids. Black stink bugs appear to be facultative feeders on plants and other insects.”  The host plants are listed as:  “Black stink bugs have been collected in cotton, soybean and citrus. They feed on plant juices, with some documented association with Commelina (dayflowers) species. Although the black stink bug is a phytophagous species, it can also be predaceous, and has been found attacking insect larvae in cotton.”  Additional information can be found on BugGuide.  It seems the only other image of a Black Stink Bug in our archives is nine years old.

Cocoon found under lid of unused garbage can…..I carefully protected and waited to see what came out. Cocoon was gray/black and I expected a moth with little color. What a surprise! Appears to be big Swallowtail Moth, 4-5 inches tip to tip. I can’t find anything exactly like it searching the Web.
I don’t know if this critter is kind of rare down here – Ivins, Utah.

Two Tailed Swallowtail

Two Tailed Swallowtail

Hi Kent,
This Two Tailed Swallowtail,
Papilio multicaudatus, is a butterfly, not a moth.  According to the Utah Bug Club:  “Two Tailed Swallowtail butterflies are large and gorgeous and can occasioanlly be found patrolling neighborhoods that have ash trees (Fraxinus pennsylvanica) growing along the street. These same ash trees serve as the larval host plant for this butterfly. Adults appear on the wing from mid-May through July with a few fresh adults appearing for a small second flight in September. Although finding adults of the Two-Tailed Swallowtail is somewhat inconsistent in our cities, males can usually be found with much more regularity cruising our canyons and ravines in May and June. Caterpillars can be found on choke cherry (Prunus virginiana) from June through August in the mountains.”  BugGuide provides this information:  “Trivia: This is probably the largest species of Butterfly in North America, with spread specimens sometimes pushing 6 inches in wingspan. However, the Giant Swallowtail – Papilio cresphontes (which definitely averages smaller) is consistently listed as the largest species, and indeed some females of that species can reach very large proportions as well. Occasionally nearly as large is also the Eastern Tiger Swallowtail – Papilio glaucus. So, on an average, everyday basis, P. multicaudatus is largest, but as for the largest specimen recorded, it is probably an open contest.”  By all accounts, this is a early sighting.
