I found this bug in my house on a windowsill. I have never seen it before.

Ivory Marked Beetle

Ivory Marked Beetle

Dear Terry,
This is an Ivory Marked Beetle.  According to BugGuide:  “hosts include a wide variety of hardwoods (oak, ash, hickory, locust, chestnut, maple, elm, beech, cherry); larvae bore in heartwood” and “Notorious for emerging from furniture after as many as 10-40 yrs.”  You just need to determine if this individual happened to wander in from the outside or if it emerged from a piece of furniture you have in your home.  We tend to lean toward the former.

Dear Inazuma,
In a sense, you and your friend are both correct.  These are Banded Net-Wing beetles,
Calopteron reticulatum, and based on this Alamy image, the species ranges as far south as at least Costa Rica.  You image depicts quite a mating frenzy.

What is this lovely little guy? He looks like he has dropped in from outer space or a 70s disco party. Will he be staying for dinner? If so, which of my pants will be served up?

Please tell me what this is! I have found 2 so far in my kitchen… July in NJ. They don’t seem to be doing anything wrong but they are so big! I would like to know if they are dangerous in any way. Thank you so much!

Dear TB,
Though we always get reports of Brown Prionids each summer, this year there seems to be more than the usual number of sightings.  We suspect they are being attracted to your kitchen because of lights at night.

Unusual find for our location, and we have no grapevines nearby. Beautiful beetle.

Grapevine Beetle

Grapevine Beetle

Dear Derek,
You are correct that this is a Grapevine Beetle, and according to BugGuide:  “Adults feed on grape (Vitis) foliage and fruit, both wild and cultivated species. Not a serious pest. Larvae host on dead
Acer, Celtis, Juglans, Malus, Platanus, Quercus, Ulmus spp.”  Though we don’t want to take the time to research all genera of larval hosts, they include maple, walnut, oak and elm and we are relatively certain some of those trees are found nearby.  Also, the adult plant host list might be incomplete.  Folks who want to start butterfly gardens quickly learn that if they do not have caterpillar host plants to produce the butterflies, they will not have many visitors to the flowers they plant.

Dear bugman,
Hello old sport was wondering if you could help me I.d. this scoundrel. Only have seen them at night, mostly seen flying into my garage from the outside. My brother says they fly sort of upright rather than parallel to the ground. Summer time in Northern New Jersey Suburbia. Checked numerous bug data bases of new jersey insects and came up empty handed. Thanks!

Dead Brown Prionids

Dead Brown Prionids

Dear Gene,
These are Brown Prionids,
Orthosoma brunneum, and according to BugGuide:  “Breeds in poles, roots(?) in contact with wet ground” so they may be emerging from dead stumps you have in the vicinity.  They are also attracted to lights.  We are tagging this posting as Unnecessary Carnage as these two Brown Prionids do not look like they died of natural causes.
