What does ERCAL look like? 

The female parasitoid is bright yellow with green eyes. The males are dark yellow to brown. Female antennae consist of five segments and male antennae three. The parasitoid is about 0.75 mm in size. All developmental stages, except the adults, are found inside the host body (larvae or pupae of whitefly). The pupal whitefly skin turns yellow during parasitoid development. The coloration is not affected by whitefly species. Adult parasitoid emerges through a small round hole.
