Well it’s just a little worm but it’s infesting my sister’s potatoes and tomatoes. I think a hornworm. ‘ b
Sorry, no idea about North American insects. But It doesn't look very good, if all it does is eat up your crop. If it's a caterpillar, then you should be seeing cocoons too. In which case I think some of them should be allowed to be there. Because when they become butterflies, whatever they eat from your garden - They pay back by pollination.
Do not kill caterpillars before properly identifying them. More are helpfull and wanted than dangerous. I'll do some searching tomorrow.
I see those here,, some type of butterfly ! Monarch ? not a hornworm ! https://www.google.com/search?q=tomato+hornworm+pictures&ie=utf-8&oe=utf-8&client=firefox-b this is a hornworm !
http://agriculture.vic.gov.au/agriculture/pests-diseases-and-weeds/pest-insects-and-mites/armyworms I am thinking it is an army worm of some variety or other. destructive! the easiest way to control them is to use Bt also known as DiPel or Spinosad. some is powder some is liquid application. it is a bacteria naturally found in the wild and once the worm/caterpillar munches on the leaf that has the bacteria on it... the worm feels full and does not eat anymore thus eventually starving itself to death.
looks larger than army worm ! dont see any damage on leaf ! is it just on the leaves or is it eating them ? do you have cabbage or cole plants close by ?
