Red Ladybird
 |
|
| [Note Guidelines] Photographer's Note |
Ladybird adults are oval, range in length from about 1 mm to over 10 mm depending upon species, and have wings. Females on average are larger than males. Adults of some species are brightly colored. Their mandibles are used for chewing. Adult ladybirds are able to reflex-bleed from the tibio-femoral articulations (leg joints). The blood (hemolymph) is repellent by having a repulsive smell as well as containing (in some species) various alkaloid toxins (adaline, coccinelline, exochomine, hippodamine, etc.). The hemolymph is yellow and its repellency and toxicity are believed to be a defense mechanism against predators. Some people have claimed that the bright (red on black, or black on red) colors of some adult ladybirds are aposematic, which is to say that the colors warn would-be predators that the beetles are distasteful or toxic.
Most species of ladybirds are considered beneficial because they are predators of Homoptera or Acarina, many of which are considered to be pests. |

Hi Gabriel,
This is definitely a leaf beetle (Chrysomelidae), probably of the genus Cryptocephalus.
Best regards,
Dmitry
