Although this card's effect revolves around Insect-Types, the egg & nest in the artwork looks more like a bird's eggs and nest.
Also, this card's TCG name says Imitation, however its effect does not resembles imitation/copying at all. Alternatively, the "eggs" in the artwork are hatching, indicating that the "insects" inside are growing. This is supported by the fact that you Special Summon an Insect-Type monster that is 1 level higher.
This card works off of the idea of insects imitating another creature's eggs for safety so that their eggs have a greater chance to hatch.
