Assassin Bug

Dear Jeff,
Assassin Bugs in the genus
Zelus will bite readily if carelessly handled, and the bite is reported to be quite painful, but it is not considered dangerous to humans.  This is a beneficial predator.

I was hiking in Organ Pipe Cactus National Monument on 2-12-17 and discovered this bug on the top of a peak, elevation 3000 ft.

Blood-Sucking Conenose Bug nymph

Dear Curt,
Because of press coverage, many folks send us images mistaking Leaf Footed Bugs for Blood-Sucking Conenose Bugs in the genus
Triatoma, but you have the real thing.  This is an immature Kissing Bug in the genus Triatoma, a group known to spread Chagas Disease, though most cases are from the tropics.  Here is a BugGuide image for comparison.  According to BugGuide:  “Tetrapod blood, mostly mammalian, but avian, reptilian and amphibian hosts are recorded. The most common wild hosts are wood rats (Neotoma) but other common ones include armadillos, opossums and raccoons (possibly also skunks); synanthropic species may feed on livestock (horses, cattle, chickens), pets and humans.”  BugGuide also states:  “Bite can cause severe allergic reaction in humans. Bite and defecation into bite can transmit Chagas disease, caused by Trypanosoma cruzi, a protozoan, whose most notorious vector is the South American T. infestans. The North American species do not normally defecate at the site of the bite, and thus do not normally transmit the disease, though they can carry the parasite (Vetter 2001). Rare vector-borne cases of Chagas disease have been noted in the so. US. ”

I found this bug near grass in Montgomery, Alabama in February, but the weather has been spring-like. Its body was about 3/4 of an inch. Do you know what it is? Thank you!

Immature Milkweed Assassin Bug

Dear Sheila,
This is an immature, beneficial, predatory Milkweed Assassin Bug.  Though they prey upon many plant feeding insects in the garden, they have been reported to deliver a painful bite if carelessly handled.  Immature nymphs are wingless while adults have wings and can fly.

Thank you!  Such a fast reply.

Hi, im working in australia at the moment and this guy got into my boilersuit and bit my leg! The closest thing i could find on google was a large milkweed bug but it doesnt look exactly like the pictures, and google says they dont bite? Unfortunately my colleague stepped on him before i could take a picture of him and take him outside. I also seen a spider that one of the locals told me is a red back spider, but again it doesnt look like the pictures on google. Just curious as we dont have any of these guys back home and wouldnt want to tell people its the wrong bug!

Assassin Bug

Dear Jon,
We feel confident that this is a male Ground Assassin Bug in the genus
Ectomocoris, but the Brisbane Insect site only has images of wingless females and we only have images of wingless females in our archive.  We located a thumbnail of a male Ground Assassin Bug on the Atlas of Living Australia, but we cannot find the page with the full sized image.  We also located these images of mounted specimens on the Swedish Museum of Natural History.  The Spider is NOT a Redback

Subject: Two insects and Cordyceps
Location: Ecuador, Yasuni adjacent to Napo River
February 4, 2017 8:34 am
During January 2017 I was in the Yasuni area, adjacent to the Napo River of Ecuador. During the hours of darkness I was photographing the very small insect on the top of the plant that had been infected by the cordyceps fungus. When along flew the green insect and settled beside the dead one. Body size of the insect is about 2cm or 3/4 of an inch. Is the green insect an assassin bug and what type? Do you think both insects are the same? There had been a lot of rain at the time I was there. It was very hot and humid and low altitude.

Assassin Bug Nymph and Adult Assassin with Fungus Infection

Dear Moira,
Both insects in your stunning image are Assassin Bugs.  The one with the Fungus Infection is a winged adult and the other an immature, wingless nymph, but we cannot state for certain that they are the same species, but we believe that is a good possibility.  You indicated that the living one “flew” and we suspect you stated that incorrectly as it has no wings.  Again, you image is positively stunning.

I managed to take a picture of this bug that scared the living hell out of me a few years ago and I’ve been wanting to ID it ever since.

Wheel Bug

Dear Joseph,
Predatory Wheel Bugs are not aggressive towards humans, but we would not want to eliminate the possibility that a bite might occur if a Wheel Bug is carelessly handled.
