Many coccinellids lay their eggs directly in aphid and scale insect
Form (education) owing to the 4-year college/university system. If there is more than one form for each year group they will normally be differentiated by letters, e.g., "upper four B", "lower two Y". Schools do not follow a consistent pattern in naming forms. Another common identification for form, and one of the most common in New Zealand, is the number of the year they are in, followed by the initials of the teacher who takes the form class.
