Default beetle ID

I found this guy on one of my plants a couple days back - probably an eggplant but maybe a pepper. Doesn't look like the cucumber beetles I've seen - any ideas?
1/4" long slow mover, climber, reluctant or unable to fly

that bugger is a potato beetle. where there's one there's more. look for clusters of orange eggs on undersides of leaves. pick and squish relentlessly.
the larvae will feed voraciously on any solanacea plant including potato, tomato, eggplant etc although they seem to prefer potato best of all

I have seen both colo potato beetle and false colo beetle here...but they are about 1/2", not 1/4". They also have many more stripes. For example, this page http://www.omafra.gov.on.ca/IPM/engl...adobeetle.html
I like this part-
Often Confused With
This is an insect that is never confused with any other pest.

This little guy is about the size of a striped cucumber beetle, but not a fast crawler and quick flier like cuke beetle.

A couple weeks ago I caught a couple false colo beetles in my home garden and killed their eggs, and saw one regular colo beetle at another garden this year. This guy does not resemble them or any pics of them I have ever seen.

It does not look like the 3 lined potato beetle to me. It has no "neck".

That three lined potato beetle is put together like a cucumber beetle.

The beetle I found has a different thorax. I can't seem to find a pic that matches using google search. I have never paid great attention to bugs over the years, but I when I saw this guy it was one I didn't recognize. The color said "foe". I'll have to see if I can find more. Japanese beetles just started showing up a couple days back so I'll be looking every few days.

Found it, three striped lady beetle. The thorax looks like a ladybug and it acts like a ladybug so on the umpteenth search of google I found a grainy pic. Striped Ladybird Beetle was the magic search term.

http://wiki.eanswers.com/en/Coccinellidae

Of course, now I am trying to find a source other than a wiki because I am seeing the same grayish pic a whole lot of places and some stating this bug is from India. lol

I am not seeing antennae in the pics either so....I don't know. This one died in the cup left outside, so I can't tempt it with aphids or eggplant leaf anymore.

Definitely not a lady beetle.

I think it's one of the Disonchya, i.e., striped flea beetle? Right size and shape, though I don't see the exact coloration of the specimen you found in the available photos here: http://bugguide.net/node/view/4520

They are a pest.

http://durgan.org/2016/June%202016/7...mlineata/HTML/ 7 June 2016 Colorado potato beetle (Leptinotarsa decemlineata)
The Colorado Potato Beetle surfaced in my garden today. Three adults were found and numerous larvae and eggs. Control is by picking and destroying all, usually several times a day. A large infestation requires the application of chemicals. The beetle cannot be ignored, since they multiply rapidly and can destroy a potato crop in a few days. The bug is ubiquitous and few gardens are without them in Canada.
