English: Extreme sharp and detailed microcosmic portrait of a garden tiger moth Arctia caja caterpillar taken with two lenses MC Jupiter-37A, which was made in 1985, and a retro lens Zenitar-M 1,7/50, made in 1982, as one lens, stacked from 202 shots into one very sharp photo. Magnificafion is 2,5x. This photo is a part of a series of macro portraits of butterflies, moths and their caterpillars. "The garden tiger moth or great tiger moth (Arctia caja) is a moth of the family Erebidae. Arctia caja is a northern species found in the US, Canada, and Europe.The moth prefers cold climates with temperate seasonality, as the larvae overwinter, and preferentially chooses host plants that produce pyrrolizidine alkaloids. However, garden tiger moths are generalists, and will pick many different plants to use as larval host plants. The caterpillars of this species are, like many caterpillars of the tiger moth family, “fuzzy” in appearance, leading them to be called "woolly bears" by casual observers.Once the caterpillars reach a certain size, they acquire hollow tubes that often contain irritating compounds. The larvae depend upon the host plant for their toxic compounds, which they convert from plant defense compounds to larval and adult protection compounds. The caterpillars can grow to a maximum size of 6 cm (2.4 in) long." (Wikipedia)
