Hypsithocus hudsonae, sometimes called the alpine shield bug[1] or black alpine shield bug, is a species of flightless shield bug endemic to New Zealand.[2] Few specimens have ever been collected and these have come from a relatively narrow geographical range. The New Zealand Department of Conservation classifies this species as 'At Risk,' with qualifiers 'data poor' and 'range restricted.'[3]
Description
[edit | edit source]H. hudsonae are dark brown shield bugs, 7–9 mm in length. Their bodies are oval shaped and flattened.[4] Nymphs appear similar to adults except the margins of their bodies are pale brown.[5] It is the only flightless New Zealand shield bug.[1]
Life history
[edit | edit source]As with many species of Pentatomidae, H. hudsonae nymphs hatch from eggs and pass through five instars before reaching adulthood.[1]
Ecology
[edit | edit source]Specimens have only ever been collected from a small number of mountain sites in Central Otago 1200–1700 m above sea level.[4] Their limited range may be explained by a lack of dispersal ability, as adults are flightless.[1] The species is herbivorous, and has been collected from Veronica odora, so may feed on that species.[4] Mating is likely to occur in summer and the species probably only has a single brood each year.[4]
