Dear Perry,
This is a Metallic Borer or Jewel Beetle in the family Buprestidae.  We cannot say for certain to which species it belongs, but you can see some Spanish Buprestids on the Living Jewels European Buprestidae Blog that were documented in Spain in June 2013.

Black Fire Beetle

Black Fire Beetle

Dear ok,
We immediately recognized this as a Metallic Borer Beetle or Jewel Beetle from the family Buprestidae, and when we researched species in Alaska, we discovered, much to our delight, that this appears to be a Black Fire Beetle or Fire Bug,
Melanophila acuminata, which according to a poster on BugGuide, is “famously known for its habit of flocking to freshly burned and sometimes still smoldering pine trees to mate and oviposit.”  According to the University of Alaska at Alberta Entomology site:  “Evans (Ecology 47:1061-1065,1966) demonstrated that these beetles can detect, infrared sources using paired receptors situated on the mesothorax near the coxal cavities and orientate towards the heat source. The structure of these receptors, are figured in Evans and Kuster (Can. Ent. 112:211-216,1980). Adults continue to be attracted to burned trees in the year following a fire.”  The site also states:  “These beetles may use most any conifer for larval development (Bright 1987). In Alberta it has been reared from white spruce and fire killed jack pine.”  According to the Montana State University site, the host trees include ” Balsam Fir, Grand Fir, Yellow Birch, Monterey Cypress, White Spruce, Lodgepole Pine, Eastern White Pine, Red Pine, Northern White-cedar; adults – various species of spruce, pine, cedar ” and “Size: 8-12mm”  which seems right for your individual if that is a pierced earring in your image.  Was this individual by chance found near a recent fire?

Ah, yes. Crawling up your pants leg and gnawing on your skin is what they excel at! We firefighters just call them Little Bitey B*stards because they show up to every fire by the thousands.

This bug was found on the west coast of the western cape South Africa in mid winter. It doesn’t appear to have wings

Brush Jewel Beetle

Brush Jewel Beetle

Dear Bonnie,
This is a gorgeous Jewel Beetle in the family Buprestidae, and we quickly identified it on iSpot as the Brush Jewel Beetle,
Julodis hirsuta subsp. hirsuta.  Your description of a “hairy bug” is so amusing in that entomologists who determined the scientific name decided that one reference to it being hirsute was not sufficient.  We would not entirely rule out that this might be Julodis cirrosa, also pictured on iSpot, based on this comment on iSpot from BeetleDude:  “Only two (sub)species of Julodis co-occur in the Klein Karoo, namely Julodis cirrosa cirrosa and Julodis hirsuta hirsuta. Their other subspecies are more easily identifiable, but it is really not easy to discriminate between J. c. cirrosa and J. h. hirsuta. But this set of photographs is just great! With specimens in hand, the identification would be clinched by studying sculptural patterns on the cuticle, details of the legs and the internal male genitalia, but these are just not ever visible enough on pictures not taken under a microscope and by a specialist.  Nonetheless, these pictures show lots and lots of character states one needs to take into account. I’ll skip the detail. Here are three important reasons for my identification of this beast as Julodis hirsuta hirsuta.
1. Setal brushes on dorsum confused, not in longitudinal rows, with small setal patches among the larger ones, and the setal brushes covering at least one quarter of elytral surface (different in J. c. cirrosa).
2. Majority of setal brushes on head longer than half the width of the eye (different in J. c. cirrosa).
3. Apex of underside of last visible abdominal segment truncate in the male {which this is} (different in J. c. cirrosa).”  A Brush Jewel Beetle is also pictured on BioDiversity Explorer

Thank you so much for your quick response. It was a very exciting discovery for us.

Jewel Beetle: Buprestis confluenta

Dear Matt,
We believe we have correctly identified your Jewel Beetle on BugGuide as
Buprestis confluenta.  Your Jewel Beetle appeared right on schedule because according to BugGuide, they appear:  “Primarily July (per pix posted here).”  According to Beetles in the Bush:  “B. confluenta is downright stunning! Brilliant green, perhaps with a slight coppery brown to purplish blue hue and with more or less confluent (thus the species name) fine yellow flecks densely scattered over the elytra, it is one of the easiest to identify of any species in the genus.”  We somehow feel your “Yuck!” comment is a tad bit harsh.

The sunlight reflecting off this small little bug is what got my attention. I tried to get a picture before it flew away…the original photo being about 3 feet away. I’ve never seen this kind of bug before, and posted the picture on social media in an attempt to identify it. The only answers I got was that it was a June Bug, which I disagreed. Through your wonderful site, i narrowed it down to a Jewel Bug, or a Golden Flatheaded borer. Any final clarification would be great, but I would also enjoy sharing this picture with others if it is of a quality good enough for you to use.

Golden Buprestid

Dear Yvonne,
Your self-identification is basically correct, but we would like to make a few clarifications.  This is a Golden Buprestid,
Buprestis aurulenta.  The members of the family Buprestidae are sometimes called Metallic Borer Beetles or Jewel Beetles.  Jewel Bug is a common name for a Shield Bug in the family Scutelleridae.

Hi, there are flying beetle like bugs that are eating a tree in our backyard. My dad started to notice them this year and doesn’t remember seeing then before. Please help!

Glassy Winged Sharpshooters

Dear Won Cho,
You have two different insects here, in different orders.  Two of them are Glassy Winged Sharpshooters that feed by sucking fluids from plants, and they do the most damage to new shoots.  According to BugGuide:  “A major vector of Pierce’s disease on grape. Usually not a serious pest within its native range, southeastern US. This species was accidentally introduced into so. California in the early 1990s, probably with ornamental or agricultural stock. There, it has become a serious threat to viticulture.  The biggest problem is that it can spread the disease-causing bacterium Xylella fastidiosa.”  According to the University of California Integrated Pest Management System site:  “The real problem associated with glassy-winged sharpshooter, however, is that it can spread the disease-causing bacterium Xylella fastidiosa from one plant to another. This bacterium is the causal agent of devastating plant diseases such as Pierce’s disease of grape, oleander leaf scorch, almond leaf scorch and mulberry leaf scorch. Other diseases to landscape plants in California include sweet gum dieback and cherry plum leaf scorch. Outside of California, other strains of X. fastidiosa cause phony peach disease, plum leaf scald, leaf scorches in sycamore, elm, maple, and oak,and variegated citrus chlorosis, but these diseases have not been detected in California. It should be noted that the strain of X. fastidiosa that causes oleander leaf scorch will not cause Pierce’s disease in grapes and the strain of X. fastidiosa that causes mulberry leaf scorch does not cause disease in oleanders or grapes. At this time there is no cure for any of these diseases.”  The other insect we can only identify to the family.  It is a Metallic Borer Beetle in the family Buprestidae, and the larvae bore in the wood.  They are generally very host specific.  Telling us what tree is affected may help in further identifications.
