Can you help identify?
Hi there, I have recently moved from the UK to central Boston and have found several of these flying insects in my city center apartment. Their bodies are generally 0.5 to 0.75 inches long. I am unsure if they are attracted by light or not. Thanks in advance

Hi Mike,
We wrote to Eric Eaton to properly identify your beetle. He wrote back: “Ok, the beetle is the “Wharf Borer,” Nacerdes melanura. It is in the
family Oedemeridae, the False Blister Beetles.” Adults are usually found on flowers or foilage near water and the larvae live in decaying wood. It is common in woodsheds, cellars and lumberyards. Originally European, it has been spread around the world due to commerce.

What is this bug
Hello
I just moved into a new home and there are a few trees that need cut down. I am currently cutting down some Shagbark Hickory trees and this bug is all over the trees. We live in Western Pennsylvania. Could you please tell me what it is and if it is harmful? Please see the attached pictures.
Thank you,
Neal

Hi Neal,
Judging by the mating activity evident in your photo, you might soon have a new generation of Painted Hickory Borers, Megacyllene caryae. They attack hickory, black walnut, butternut, osage orange and mulberry. The female lays eggs after cutting deep pits in the bark. Larva bore inward and pupate under bark. Adults emerge in the spring.

Help!
We have a 7th grade science project due Monday (05-09-05). We have this insect we would like to use in the project, but don’t have any idea what it is. Can you identify it?
Thanks,
Ben

Hi Ben,
This is one of the Click Beetles known as the Eyed Elator or Big Eyed Click Beetle, Alaus oculatus. Adults eat little and larva attack roots and small creatures in the soil. Click Beetles are so called because if they are turned on their backs, they quickly flex their body making a clicking sound and flipping in the air to right themselves.

Thank you so much for your help. Gotta finish that bug project. Love your website!
Ben

Please help to identify bugs
Hi.
We have what seems like a million of these little black bugs, primarily in our finished basement. They are tiny – you can see next to the penny a comparison- but less than 1/8 inch. There are tons of them, though. We find them dead and alive. They have six legs, two antennae and a long, skinny nose/snout thing. They are semi-hard, but not so much that you can’t squeeze them. They are on the carpet (berber) and sometimes on the linoleum and concrete. Our basement is semi-underground. Meaning, if you look out the windows, the ground is a littler higher than waist level. We live in Maryland, so you can get an idea of climate/geography. Please help! We don’t know if they’re good, bad or indifferent. Thanks so much.
(Do we check your website for a reply or will you send it here? Thanks!!!)

Hi there,
We try to answer as many letters as possible. We post on the site and respond directly. You have some species of Grain Weevil, Sitophilus species. They are very small and the larvae, which do the damage in stored grains, are obese pale grubs without obvious legs.

Hi Jason,
This is one of the Long Horned Borer Beetles from the Family Cerambycidae. Larva bore in wood. Perhaps your specimen just emerged after spring metamorphosis aftel living several years in the wood. We wanted to try to be more specific, so we wrote to Eric Eaton who kindly replied: “The borer is a species of Neoclytus in the Cerambycidae. Not knowing anything more, I wouldn’t venture a species guess. They are wasp mimics of course, with those markings and overall leggy appearance, short antennae. Thanks for sharing. It is like Christmas every time I open one of your e-mails.”

black-orange bug?
Hello: your web site is really cool. My son and I found a bug outside and we don’t know what it is. We live in Phoenix, Arizona. The bug is pretty big. Maybe 1 inch long. Black body with an orange head. We found it on a leaf on our Magnolia tree. Just like to know anything about it. Is it harmless? I haven’t seen one of these bugs after living in Arizona for 10 years. So I am curious as to what it is and if it is common around here.
thanks!
Paul Avona

Hi Paul,
You have a photo of an Arizona Blister Beetle, Lytta magister. It is found in deserts in Arizona. Much of the life cycle is still unknown, but adults eat plant tissues of desert shrubs and larvae attacks grasshopper eggs in soil. Blister Beetles secrete a chemical cantharidin which causes blisters on human skin.
