PROBLEM TO BE SOLVED: To provide an insect counting device and an insect counting system capable of accurately counting insects without being affected by characteristics such as body color, body shape and body length of insects. SOLUTION: An insect counting device 3A receives a three-dimensional shape measurement data obtained by measuring a three-dimensional shape of a collecting surface 40 on which insects are stopped by a 3D scanner 2A, and a third order received by the data receiving section 30. Based on the original shape measurement data, the detection unit 321A that detects the convex portion 100 formed by the insect 10 and the number of the convex portions 100 detected by the detection unit 321A are counted to stop the insect surface 40. And a counting unit 322 that counts the number of insects 10. [Selection diagram]【課題】虫の体色、体形、体長等の特徴に影響を受けることなく、虫を正確に計数することができる、虫計数装置及び虫計数システムを提供する。【解決手段】虫計数装置３Ａは、３Ｄスキャナ２Ａにより虫が止まる集虫面４０の三次元形状を測定した三次元形状測定データを受け付けるデータ受付部３０と、データ受付部３０により受け付けられた三次元形状測定データに基づいて、虫１０が形成する凸状部１００を検出する検出部３２１Ａと、検出部３２１Ａにより検出された凸状部１００の数を計数することにより、集虫面４０に止まる虫１０の数を計数する計数部３２２と、を備える。【選択図】 図１
