1m Broad-bodied Chaser
Treve Willis
Initially thought to be a Scarce Chaser, this individual was only a worn Broad-bodied Chaser for the following reasons:
- Extensive dark patches at the bases of both the front and rear wings (on Scarce Chaser only rear wings have such extensive dark patches)
- Pterostigma more extended than on Scarce Chaser. Also appear black, not dark brown.
- Small black tip to abdomen - it is more extensive on Scarce Chaser
- Although there are no yellow spots on the sides of the abdomen, there are markings there of the same size and shape.
- Width of abdomen fits better with Broad-bodied.
- The eyes are not clearly blue

Not convinced this is a scarce chaser. More likely a broad bodied chaser - non blue eyes, hint of antehumeral stripe and bold dark patches both wings (although yellow spots on abdomen not visible)
ReplyDeleteThanks Jeremy. I think you could well be right. Although there are no yellow spots there are markings where they normally are. Difficult to see the eye colour though. So maybe a worn Broad-bodied Chaser?
DeleteAgreed - this isn't a Scarce Chaser.
