I’d really like to know what this bug is, why I’ve been seeing them so often lately, and why I have not seen them before (if that’s possible to answer).
I live in Delaware (the state in the US) and this summer I’ve been seeing these everywhere I go.

Hanging Thief

We just posted a lengthy description of a Hanging Thief.  As to why you have seen them recently, we can only respond that insect populations fluctuate due to weather conditions, food supplies and other factors.  Then again, perhaps you have just gotten more observant.

Ailanthus Webworm

Ailanthus Webworm

Dear Shannon,
This pretty native Ermine Moth is commonly called an Ailanthus Webworm.  It is one of the few insects known to feed on the invasive, exotic Tree of Heaven,
Ailanthus altissimus, which is recognized on the government website Weeds Gone Wild as being a major threat with this statement:  “Tree of heaven is reported to be invasive in natural areas in 30 states across continental U.S. and Hawaii. It is highly adaptable to disturbance and a huge range of soil types and conditions, grows best in full sun and is tolerant of drought.  Ecological Threat  A common tree in urban areas where it causes damage to sewers and structures, ailanthus poses a greater threat to agriculture and natural ecosystems. It is a vigorous growing tree and prolific seeder that establishes dense stands that push out natives. Tree of heaven contains chemicals, including ailanthone, that have been found to have strong allelopathic (herbicidal) affects on the growth of other plants which help it establish and spread.”  Though the native Ailanthus Webworm has adapted to feeding on an invasive plant, it is doubtful that the Ailanthus Webworm will have much of an impact on controlling the spread of the scourge.

Dear c santana,
This impressive, predatory Robber Fly in the genus
Diogmites is commonly called a Hanging Thief because they frequently hang by one or two legs while feeding.

Hello, we were intrigued by this bug spotted on our cedar tree. We wondered what it might be. It’s about an inch long, it’s a dull olive green and has four faint black spots.
We think it’s a beetle because of the elytra?
Cheers and thank you!

Hi, Daniel:
Sure, this is a “Linden Borer,” Saperda vestita.  Nice beetle!

Good morning Bugman.
My son and I were staying at a hotel in Virginia (just outside of Shenandoah National Park), in mid-July. He saw this creature on the wall, and this is one we’ve never seen before. It didn’t move, even after the flash from the camera. Thank goodness, because those mandibles look ferocious.

Female Dobsonfly

Dear Bob M.,
This is a female Dobsonfly, and your timing is perfect as we just posted an image of a sexually dimorphic male Dobsonfly.  Though his mandibles are much more impressive looking, they are unable to bite human skin, but the smaller and more utilitarian mandibles of the female are capable of delivering a painful bite that might even draw blood, so you should handle her with caution.  You can compare this image of a male and female Dobsonfly side by side and also view the courtship process.

Hi i live in northeastern pa . I found this bug outside of my work on the wall and was wondering what it was? Many people were freaking out over it because of the way it looked and its size. It was about 5 inches long . Never saw one before.

Dear lordnikon,
Though you have the spelling wrong, you are correct that this is a male Dobsonfly.
