Description:

This was seen about four minutes later than H1 of the previous post, and about 20 yards away. There is strong structural similarity but my impression at the time was of two different individuals. This was later reinforced by the appearance of the antennae which seem to be longer and thinner in H1. From the composite image shown, a rough estimate of antennal to body length (excluding ovipositor) comes out at 0.96 for H1 and 0.65 for H2

Antennal length

Are antennae extensible? H1 was vibrating its antennae in full sun while those of H2 were being used in process of active exploration.

The antennae don't extend but

The antennae don't extend but they are very flexible.
