54.005 Zygaena loti (Slender Scotch Burnet) 0167
ws: 25-30mm; fw: 14-16mm; June to early July; common bird's-foot trefoil (Lotus corniculatus); RDB - Mull, Ulva
ID: Spots 5+6 merged, forewing thinly scaled, legs partly yellow.
Note - spot 3 may be divided by vein along costal border of discal cell.
Specimen §2 has confluent spots 2+4
Z.exulans (Scotch Burnet) is 5-spotted due to the absence of spot 6 - so that the spot nearest the termen is much smaller than in Z.loti. Spot 1 is much longer than spot 2. And it is restricted to mountains around Braemar.
Z.viciae (New Forest Burnet) is also 5-spotted due to absence of spot 6 - so that the spot nearest the termen is small; its hindwing has a relatively broad black border
Z.filipendulae (Six-spot Burnet) usually has distinct spots 5 & 6, but they may be merged, in which case it can be distinguished by the more thickly scaled forewing and all-dark legs.
Z.trifolii/lonicerae (Five-spot/Narrow-bordered Five-spot Burnet) are 5-spotted due to absence of spot 6 and the spot nearest the termen is small. In Z.trifolii spots 3+4 are often confluent. Both species have all-dark legs and are more thickly scaled than Z.loti
Z.purpuralis (Transparent Burnet) has 3 longitudinal streaks formed from spot 1, 2+4, 3+5+6.
