Adult beetles may be visually confused with L. juncta, which is the false potato beetle. Unlike the Colorado potato beetle, it is not an agricultural pest. L. juncta also has alternating black and white strips on its back, but one of the white strips in the center of each wing cover is missing and replaced by a light brown strip. [7]

The spotted cucumber beetle is a serious pest of vegetables and is a very common insect on all sorts of flowers. The Colorado potato beetle, Leptinotarsa decemlineata, attacks potatoes and other members of the Solanaceae. The Asian long-horned beetle is a serious pest of trees where it has been introduced. [citation needed]. It seems almost ...
An adult beetle can eat about twenty three eggs or three third instar larvae of the Colorado potato beetle each day. [4] After mating, the females lay eggs singly in the soil near potato plants. A glandular secretion causes soil granules to stick to the eggs which serves to camouflage them. Each female can lay up to 1300 eggs over the course of ...
The Colorado potato beetle has evolved resistance to 52 different compounds belonging to all major insecticide classes. Resistance levels vary across populations and between beetle life stages, but in some cases can be very high (up to 2,000-fold). [21]

Solanum rostratum is the ancestral host plant of the Colorado potato beetle, Leptinotarsa decemlineata, but this pest adopted the potato, Solanum tuberosum as a new (and more succulent) host, a fact first reported in eastern Nebraska in 1859. It then expanded its range rapidly eastward on potato crops in the next two decades. [10] Can be invasive.
In 1867, farmers in Illinois and Indiana found that Paris green was effective against the Colorado potato beetle, an aggressive agricultural pest. Despite concerns regarding the safety of using arsenic compounds on food crops, Paris green became the preferred method for controlling the beetle.
