31. A sharp spine is placed on the outer margin of the antennal peduncle near the base of the scaphocerite. 32. Antennal clocks exist in monarchs, and they are likely to provide the primary timing mechanism for sun compass orientation.33. Antennal lobe projection neurons are the source of the cholinergic input, and the GABAergic input is from protocerebral neurons.34. Tetramerocerata has a 4-segmented and scarcely telescopic antennal stalk, 6 tergites, and 8 10 pairs of legs. 35. After the pair has made antennal contact, a courtship period may occur during which the character of the call changes. 36. Sleep in some invertebrates has also been extensively studied, e . g ., sleep in antennal immobility, etc. 37. The head in relation to the eyes is wider than in Lycaenidae, making the antennal bases further away from the eye. 38. In addition, they have reduced setae on the antennal flagellum, but this may be an adaptation bearing little phylogenetic information. 39. The similar representatives of the genus of " Berytinus " are smaller and have a much shorter second antennal segment. 40. In " Bombus vestalis ", the fifth antennal segment will be the same length as the third and fourth together.
