State one observable difference between the male and female shown in Fig. 3.1.
In the space below, draw the male insect as it appears in Fig. 3.1.
C and D show the length of the female insect. D marks the end of the abdomen. Join C and D with a straight line on the photograph. Measure the length of the line and write it down. Calculate the actual length of the insect and give the answer to the nearest whole number.
Use the key below to identify the insect and write down its name. 1 wings longer than abdomen → $\textit{Oedemera femoralis}$ wings shorter than abdomen → go to 2 2 colour brown → $\textit{Oedemera barbara}$ colour green or grey → go to 3 3 length $5$-$6.5\text{ mm}$ → $\textit{Oedemera lurida}$ length $7$-$11\text{ mm}$ → $\textit{Oedemera nobilis}$
