Map type:

In the Adults column (Ad) enter a counted number if possible, or the suitable letter code as below. This total includes tenerals and all adults that are engaged in breeding activity, such as tandem or copulating pairs and/or ovipositing females, but does not include emergents. Please attempt to be as accurate as possible with this total count. If a count is not possible, use the code, A = 1; B = 2-5; C = 6-20; D = 21-100; E = 101-500; F = 500+. Similar counts or codes are used to indicate breeding activity such as tandem or copulating pairs (Co), where the number of pairs should be counted. These pairs should also be included as two adults in the 'Ad' count. In the same way, ovipositing females (Ov) are counted separately, but also form part of the overall adult total. Any larvae (La), exuviae (Ex) and emergents (Em) present should be recorded, but these do not form part of the adult total. An emergent dragonfly (Em) is one that is in the process of emerging or has just emerged, but is judged still to be at its emergence site. This should not be confused with 'teneral' adults, which may have flown in from elsewhere and therefore should be included in the adult count. Deformed adults incapable of flight and judged to be still at their site of origin, can be included as emergents.
